PLAGUES & PESTILENCES: The Alarming Spread Of The Zika Virus - Dominican Republic Confirms 10 Cases, 17 Others Suspected!

This 2006 photo provided by the Centers for Disease Control and Prevention shows a female Aedes aegypti mosquito in the process
of acquiring a blood meal from a human host.

January 24, 2016 - DOMINICAN REPUBLIC
- The Dominican Republic said it has 10 confirmed cases of the mosquito-borne Zika virus, the ailment suspected of causing serious birth defects in newborns.

Altagracia Guzman, the Caribbean country's health minister, said lab testing of samples sent to the United States had confirmed Zika in 10 out of 27 suspected cases.

"In light of this finding, it is imperative to adopt strict measures across the nation to prevent and contain this illness," Guzman said.

Zika has been linked to a birth defect known as microcephaly, when babies are born with malformed and abnormally small heads.

It is also associated with a higher incidence of miscarriages.

Proposed measures to contain the illness include stepped-up mosquito eradication, including eliminating standing water that can be breeding grounds for the insects. - Yahoo.





OMEN: Plagues & Pestilences - Baby Girl Born With Only Half A Head And Bulbous Eyes In India?! [PHOTOS]

The baby, born at Sai Nursing Home clinic, did not have a fully developed head and died shortly after birth

 January 24, 2016 - INDIA - A baby girl has been born in India without a head that has left her with shockingly protruding eyes.

Savita Rani, 32, from Amroha district of Uttar Pradesh, in northern India, gave birth to her 'miracle baby' on Tuesday after a natural birth.

But soon after the birth she became the talk of the town due to her shocking features. A large number of people started to even gather outside the at Sai Nursing Home clinic in the hope of seeing the 'miracle child'.

Two days later, however, the baby girl tragically died of heart failure.

Dr Kusum Lata, 30, a gynaecologist at Sai Nursing Home, said: 'These complications occur due to incorrect and irregular eating habits of the mother during pregnancy.

'This is why we as doctors keep emphasising on regular check ups of the women during pregnancy so we can try to guide the mother and hope to avoid such birth abnormalities.


According to doctors, the abnormalities occurred due to 'incorrect and irregular eating habits of the mother during pregnancy'

The mother, who already has three very healthy children, faced extreme difficulties during labour and lost a lot of fluid and blood



'The baby's eyes were so large that she was born with them already open because her head had not formed properly.

'She didn't have normal movements like other babies when they are born - she wasn't crying or moving.'

Dr Lata added it was a miracle both mother and child survived as long as they did.

The mother, who already has three very healthy children, faced extreme difficulties during labour and lost a lot of fluid and blood.

He explained that the baby girl's brain had not formed properly in the womb and her heart had kept her alive.

The mother has now been discharged from hospital and is trying to come to terms with her loss. - Daily Mail.

MONUMENTAL DISASTER IMPACT: Time To Dig Out - Historic Snowstorm Comes To An End; Caused Transport Chaos And Heavy Coastal Floods, Turning Once Busy Streets Into Ghost Cities; At Least 19 Dead On U.S. East Coast; ALL-TIME SNOWFALL RECORD Broken In Several Cities; The SECOND BIGGEST Snowstorm In New York Since 1869; 40 INCHES At Glengary, West Virginia; Snowstorm To Hit Great Britain On Tuesday! [PHOTOS]


January 24, 2016 - UNITED STATES - The Huge snowstorm, ‘Jonas’, which hit and paralyzed the US East Coast has moved away, leaving at least 19 people dead.

A travel ban has already been lifted for New York, but not for Washington – and 700 flights are not expected to take off on Monday.

The deadly blizzard killed at least 19 people, according to officials. Most of them – 13 – died in car crashes in Arkansas, North Carolina, Kentucky, Ohio, Tennessee and Virginia. In Virginia, two more died of hypothermia.

One person also died in Maryland.

In New York City three people also died while shoveling snow, CBS News reported, citing police.


Jonas became the second biggest snowstorm in New York since 1869 with the snow dropping at a level of 26.8 inches (68.1 centimeters) in Central Park.

It was just 0.1 inches short of the record heaviest New York blizzard which occurred in February, 2006.


The all-time record was registered in Baltimore, Maryland, with 29.2 inches (about 74 centimeters) of snow, as well as in Harrisburg, Pennsylvania with 28.6 inches (about 71 centimeters) of snow, according to the Weather Channel.

The biggest amount of snow was registered at Glengary, West Virginia – 40 inches (101.6 centimeters).

“This is kind of a Top 10 snowstorm,” weather service winter storm expert Paul Kocin told CBC.


The US East Coast is to return back to normal life. New York has already lifted a travel ban imposed on Saturday while Baltimore Mayor Stephanie Rawlings-Blake asked residents to remain off the road in order not to disturb crews clearing the streets.


WATCH: YouTuber snowboards through NYC.




Airports around Washington DC are likely to remain closed on Sunday. Moreover, around 700 Monday flights have already been canceled – in addition to about 7,000 cancellations at the weekend.


The snowstorm struck the US on Friday evening causing transport chaos, heavy coastal floods in New Jersey and Delaware as well as strong winds 120 kilometers pro hour – a wind speed registered in at Dewey Beach, Delaware, and Langley Air Force Base, Virginia, AP reports citing weather services.



The storm turned always busy New York and Washington DC into ghost cities with empty streets.According to weather forecasts, snowstorm Jonas, which urged 11 US states to declare emergency, is to cross the Atlantic Ocean and to hit Great Britain on Tuesday causing heavy rains. Warnings have already been issued for most of Wales, north-west England, and south and west Scotland, Sky News reports. - RT.

January 24, 2016 - JAPAN - Two people died and more than 100 were injured Sunday as a cold air mass gripped Japan, with record-breaking heavy snowfall in western and central areas of the country.

With a bitterly cold air mass in place above the Japanese archipelago, heavy snow fell and strong winds blew in Sea of Japan coastal areas from the central to southwestern regions on Sunday, disrupting air and land traffic.

The first snowfall in almost 115 years was recorded on Amami-Oshima island, a subtropical island located some 380 km (235 miles) southwest of the city of Kagoshima, while temperatures fell to record lows in western and southern Japan.

In usually warm Naha in subtropical Okinawa Prefecture, temperatures plummeted to 8.9 degrees Sunday morning, far below January's average low. The temperature in the town of Kunigami, in the north of the main island, it dropped to a record-low 4.2 degrees Celsius at 6 p.m.

The Meteorological Agency called for vigilance against strong winds and high waves across much of the country as well as heavy snow and snowstorms in the Hokuriku region and in western Japan through Monday.

The bad weather caused delays in high-speed train services on Central Japan Railway Co.'s Tokaido Shinkansen Line, West Japan Railway Co.'s Sanyo Shinkansen Line and Kyushu Railway Co.'s Kyushu Shinkansen Line, as well as cancellations and delays on the Hokuriku, Sanyo, Sanin, Dosan, Nagasaki and Kagoshima lines.

All Nippon Airways and Japan Airlines had canceled a total of 286 domestic flights by 5 p.m.

Most sections of expressways in the Kyushu region were closed to traffic. Parts of the Tokushima Expressway and the Matsuyama Expressway in Shikoku, as well as the Hokuriku Expressway, were also closed.

Sleet was observed intermittently at Naze observatory on Amami-Oshima island soon after 1 p.m. As sleet is included in the category of snow, it marked the first snowfall on the island since Feb. 12, 1901.

In the Chugoku region where the snowfall was heaviest, the town of Kita-Hiroshima in Hiroshima Prefecture recorded 142 cm (55 inches) of snow, while Suzu, at the north end of the Noto Peninsula in Ishikawa Prefecture saw 59 cm (23 inches) of snow.

Nagasaki had 15 cm (5.9 inches) of snow, Kagoshima 10 cm (3.9 inches) and Saga 6 cm (2.3 inches).

With the cold air mass in place above the archipelago, temperatures hit record lows in many western locations.

The mercury remained below freezing in Fukuoka, Kumamoto and other cities in the Kyushu region throughout the day, while the temperature dropped to minus 9.4 degrees Celsius in the town of Kami, Hyogo Prefecture, and minus 5.8 degrees at Tottori Airport in Tottori. Both were the lowest on record.
In Aomori Prefecture, a woman died after she fell from a roof as she was trying to remove snow, and in Tochigi Prefecture, a man died in a weather-related traffic accident.

Around the country, over 100 people suffered injuries due to weather conditions, with 65 cases recorded in Kyushu as of 5 p.m., according to a Kyodo News tally of reports from local authorities.

Shortly after midnight Saturday, 11 cars and other vehicles were involved in pileups on a road in Fukuoka Prefecture in freezing condition amid snowfall, injuring two men, police said.

Around 6 a.m. Sunday, six teenagers who had climbed 847.5-meter-high Mount Kusembu, which straddles Fukuoka and Saga prefectures, called for help, saying they were unable to descend due to snow. Local firefighters found them near the peak of the mountain and rescued them about 90 minutes later.

For the 24 hours to 6 p.m. Monday, maximum snowfall is forecast to reach 70 cm (27.5 inches) in Hokuriku, 60 cm (23.5 inches) in the Tohoku region, 50 cm (19.5 inches) in the Kanto-Koshinetsu, Tokai, Kinki and Chugoku regions, 40 cm (15.7 inches) in northern parts of Kyushu, and 20 cm (7.8 inches) in southern parts of Kyushu and in Shikoku.

Through Monday, winds are expected to mark maximum speeds of 30 to 35 meters in many parts of Japan. - The Japan Times.

ANIMAL BEHAVIOR: Migratory Patterns And Disaster Precursors - 3 More Sperm Whales Wash Up Along The North Sea Coast At Skegness Beach, UK; And Whale Calf Washes Up On Marbella Beach, Spain?!

Two of the dead sperm whales

January 24, 2016 - EARTH - The following constitutes the latest reports of unusual and symbolic animal behavior, mass die-offs, beaching and stranding of mammals, and the appearance of rare creatures.

3 more sperm whales wash up along the North Sea coast at Skegness beach, UK

Whales are thought to be part of same pod as another discovered on the Norfolk coast on Friday

Three dead sperm whales have been discovered washed up on the Lincolnshire coast.

One of the whales was found dead on Skegness beach at about 6.30am on Sunday morning, while the two others were discovered a few miles south at about 8.30pm on Saturday evening.

Coastguard rescue teams from Sekegness and Chapel St Leonards were called to cordon off the area and members of the public are being advised not to come close to the dead animals.

Natalie Emmerson, from Hunstanto Sealife Sanctuary, told ITV News: "It is entirely possible that these whales at Skegness are from the same pod. If all have washed up dead it is too much of a coincidence.

"It is possible that they were on the rocks and injured themselves as they managed to free themslves."

The whale calf is the latest in a succession of dead or sick marine animals washed up on Marbella beaches.

Passersby on the beach at Los Monteros on Tuesday came across a dead whale calf on the shore. The two-metre long sea mammal showed no sign of injury leading experts to believe it was suffering from some kind of disease. The calf was removed from the beach and incinerated after an autopsy had been carried out.

The whale calf is the latest in a succession of dead or sick marine animals washed up on Marbella beaches. A few weeks ago, a dead giant turtle appeared in El Alicate. - Surin English.





FIRE IN THE SKY: Bright Fireball Lights Up Evening Skies In Finland!

January 24, 2016 - FINLAND - There were many of reports of a large, bright fireball that lit up skies over towns across southern Finland at about 8 pm on Saturday. Some eyewitnesses of the phenomenon said it looked like lightning or a camera flash. Still others reported they also heard a thunder-like rumbling afterwards.

The website of astronomy magazine Tähdet ja avaruus, which uses the assistance of astronomers from across Finland, says that there were some 200 reports of sightings of a bright flash of light in the dark skies of southern and western areas at about 8 pm Saturday.

According to Tähdet ja avaruus the flashing light was likely a meteorite but said they had not yet seen Saturday night's incident captured in a photograph.

If the suspected meteorite was photographed, it might be possible to determine its trajectory and possibly learn if the object may have reached the Earth's surface.

Large, bright meteorites are regularly seen in the skies of Finland several times a year.

PLANETARY TREMORS: Powerful 7.1 Magnitude Earthquake Hits Southern Alaska - Is Widely Felt In Anchorage; Shake Buildings In The Region; Reports Of Power Outages; No Tsunami Expected! [MAPS + TECTONIC SUMMARY] UPDATE: Video - Earthquake Shakes Alaskan Home!

USGS earthquake location.

January 24, 2016 - ALASKA -  A magnitude-7.1 earthquake hit southern Alaska early Sunday morning, awakening residents and shaking buildings in this earthquake-prone region.

The earthquake struck about 1:30 a.m. Alaska time and was centered 30 miles east of Pedro Bay and 160 miles southwest of Anchorage, according to the U.S. Geological Survey.

The earthquake was widely felt by residents of Anchorage, and there are reports of scattered power outages. But the Anchorage and Valdez police departments say they have not received any reports of injury or significant damage.


USGS shakemap intensity.


Anchorage resident Ron Barta says his house shook about 1:34 a.m. when the earthquake hit. Barta, 55, says the pictures on the walls started moving, but there was no damage to his house and no one was hurt.

"I was sitting here with the dogs getting ready to go to bed about 1:34 local time. ... I felt a little rumble that didn't quit for about 30 to 45 seconds. It felt like the house moved," said Barta, who is married to an Associated Press reporter.

The violent shaking woke up Associated Press reporter Mark Thiessen, who had been asleep for about two hours when then quake struck.





"I remember the bed swaying back and forth, and loud noises, enough to wake me up even after taking sleeping pills," said Thiessen, 53. "My husband came into the bedroom forcefully saying, 'Get up! Get up!' " he said. "But I was already awake, trying to figure out what was happening."

Barta, who has lived in Anchorage for about 10 years, says Alaskans on social media say the earthquake woke them up.

People were saying on social media that the earthquake "was the biggest I ever felt as long as I have lived here," Barta said.









A tsunami is not expected as a result of the earthquake, the National Weather Service said.

Seismotectonics of Alaska

The Aleutian arc extends approximately 3,000 km from the Gulf of Alaska in the east to the Kamchatka Peninsula in the west. It marks the region where the Pacific plate subducts into the mantle beneath the North America plate. This subduction is responsible for the generation of the Aleutian Islands and the deep offshore Aleutian Trench.

The curvature of the arc results in a westward transition of relative plate motion from trench-normal (i.e., compressional) in the east to trench-parallel (i.e., translational) in the west, accompanied by westward variations in seismic activity, volcanism, and overriding plate composition. The Aleutian arc is generally divided into three regions: the western, central, and eastern Aleutians. Relative to a fixed North America plate, the Pacific plate is moving northwest at a rate that increases from roughly 60 mm/yr at the arc's eastern edge to 76 mm/yr near its western terminus. The eastern Aleutian arc extends from the Alaskan Peninsula in the east to the Fox Islands in the west. Motion along this section of the arc is characterized by arc-perpendicular convergence and Pacific plate subduction beneath thick continental lithosphere. This region exhibits intense volcanic activity and has a history of megathrust earthquakes.


USGS plate tectonics for the region.


The central Aleutian arc extends from the Andreanof Islands in the east to the Rat Islands in the west. Here, motion is characterized by westward-increasing oblique convergence and Pacific plate subduction beneath thin oceanic lithosphere. Along this portion of the arc, the Wadati-Benioff zone is well defined to depths of approximately 200 km. Despite the obliquity of convergence, active volcanism and megathrust earthquakes are also present along this margin.

The western Aleutians, stretching from the western end of the Rat Islands in the east to the Commander Islands, Russia, in the west, is tectonically different from the central and eastern portions of the arc. The increasing component of transform motion between the Pacific and North America plates is evidenced by diminishing active volcanism; the last active volcano is located on Buldir Island, in the far western portion of the Rat Island chain. Additionally, this portion of the subduction zone has not hosted large earthquakes or megathrust events in recorded history. Instead, the largest earthquakes in this region are generally shallow, predominantly strike-slip events with magnitudes between M5-6. Deeper earthquakes do occur, albeit rather scarcely and with small magnitudes (Magnitude less than 4), down to approximately 50 km.

Most of the seismicity along the Aleutian arc results from thrust faulting that occurs along the interface between the Pacific and North America plates, extending from near the base of the trench to depths of 40 to 60 km. Slip along this interface is responsible for generating devastating earthquakes. Deformation also occurs within the subducting slab in the form of intermediate-depth earthquakes that can reach depths of 250 km. Normal faulting events occur in the outer rise region of the Aleutian arc resulting from the bending of the oceanic Pacific plate as it enters the Aleutian trench. Additionally, deformation of the overriding North America plate generates shallow crustal earthquakes.

The Aleutian arc is a seismically active region, evidenced by the many moderate to large earthquakes occurring each year. Since 1900, this region has hosted twelve large earthquakes (Magnitude greater than 7.5) including the May 7, 1986 M8.0 Andreanof Islands, the June 10, 1996 M7.9 Andreanof Islands, and the November 17, 2003 M7.8 Rat Islands earthquakes. Six of these great earthquakes (M8.3 or larger) have occurred along the Aleutian arc that together have ruptured almost the entire shallow megathrust contact. The first of these major earthquakes occurred on August 17, 1906 near the island of Amchitka (M8.3) in the western Aleutian arc. However, unlike the other megathrust earthquakes along the arc, this event is thought to have been an intraplate event occurring in the shallow slab beneath the subduction zone interface.

The first megathrust event along the arc during the 20th century was the November 10, 1938 M8.6 Shumagin Island earthquake. This event ruptured an approximately 300 km long stretch of the arc from the southern end of Kodiak Island to the northern end of the Shumagin Islands and generated a small tsunami that was recorded as far south as Hawaii.

The April 1, 1946 M8.6 Unimak Island earthquake, located in the central Aleutian arc, was characterized by slow rupture followed by a devastating Pacific-wide tsunami that was observed as far south as the shores of Antarctica. Although damage from earthquake shaking was not severe locally, tsunami run-up heights were recorded as high as 42 m on Unimak Island and tsunami waves in Hilo, Hawaii also resulted in casualties. The slow rupture of this event has made it difficult to constrain the focal mechanism and depth of the earthquake, though it is thought to have been an interplate thrust earthquake.

The next megathrust earthquake occurred along the central portion of the Aleutian arc near the Andreanof Islands on March 9, 1957, with a magnitude of M8.6. The rupture length of this event was approximately 1200 km, making it the longest observed aftershock zone of all the historic Aleutian arc events. Although only limited seismic data from this event are still available, significant damage and tsunamis were observed on the islands of Adak and Unimak with tsunami heights of approximately 13 m.

The easternmost megathrust earthquake was the March 28, 1964 M9.2 Prince William Sound earthquake, currently the second largest recorded earthquake in the world. The event had a rupture length of roughly 700 km extending from Prince William Sound in the northeast to the southern end of Kodiak Island in the southwest. Extensive damage was recorded in Kenai, Moose Pass, and Kodiak but significant shaking was felt over a large region of Alaska, parts of western Yukon Territory, and British Columbia, Canada. Property damage was the largest in Anchorage, as a result of both the main shock shaking and the ensuing landslides. This megathrust earthquake also triggered a devastating tsunami that caused damage along the Gulf of Alaska, the West Coast of the United States, and in Hawaii.

The westernmost Aleutians megathrust earthquake followed a year later on February 4, 1965. This M8.7 Rat Islands earthquake was characterized by roughly 600 km of rupture. Although this event is quite large, damage was low owing to the region's remote and sparsely inhabited location. A relatively small tsunami was recorded throughout the Pacific Ocean with run-up heights up to 10.7 m on Shemya Island and flooding on Amchitka Island.

Although the Aleutian arc is highly active, seismicity is rather discontinuous, with two regions that have not experienced a large (Magnitude greater than 8.0) earthquake in the past century: the Commander Islands in the western Aleutians and the Shumagin Islands in the east. Due to the dominantly transform motion along the western arc, there is potential that the Commander Islands will rupture in a moderate to large strike-slip earthquake in the future. The Shumagin Islands region may also have high potential for hosting a large rupture in the future, though it has been suggested that little strain is being accumulated along this section of the subduction zone, and thus associated hazards may be reduced.

East of the Aleutian arc along the Gulf of Alaska, crustal earthquakes occur as a result transmitted deformation and stress associated with the northwestward convergence of the Pacific plate that collides a block of oceanic and continental material into the North America plate. In 2002, the Denali Fault ruptured in a sequence of earthquakes that commenced with the October 23 M6.7 Nenana Mountain right-lateral strike-slip earthquake and culminated with the November 3, M7.9 Denali earthquake which started as a thrust earthquake along a then unrecognized fault and continued with a larger right-lateral strike-slip event along the Denali and Totschunda Faults.

January 24, 2016 - APONTE, COLOMBIA - What started with a small fissure in early 2015 is today a giant mysterious earth crack nearly a kilometer in length that crosses the village of Aponte, Colombia. The crack has caused enormous damage to roads and houses in the village of Aponte in Nariño. At least 210 families are affected by this geological anomaly.

The gigantic crack is growing and devastating Aponte, Colombia, but nobody knows its origin.

The unexplained crack in the ground is 1,200 meters long and 50 centimeters wide. At some points its depth reaches up to four meters.

The enormous crack has caused large damage to roads in Nariño. Only in Aponte 170 houses are cracked and have to be evacuated.

At least 210 families are currently affected by the growing fissure.
Since December 2015, ten families are monitoring the changes along the crack.

Results show that since December 24th the the fissure increases by 20 to 50 millimeters.

Some days, rumblings similar to wind blowing out of the ground are heard. On such days, the separation sometimes reach one centimeter.

An engineering battalion was sent by Bogota to investigate the failure.

According to the ancient Inga indians living on that ancestral land, Earth is looking for ways to draw attention to the damage it is currently suffering.
