NEW YORK — The U.S. Geological Survey is reporting a powerful undersea earthquake off the South Pacific island of Vanuatu.

The U.S.G.S. says a magnitude 7.0 earthquake struck at 5:19 a.m. Sunday local time (1819 GMT) at a depth of 28.5 kilometers (17.7 miles). Its epicenter was 69 kilometers (42 miles) south-southwest of the Vanuatu capital of Port-Vila.

 

 

The Pacific Tsunami Warning Center says no tsunami warning is in effect.

Vanuatu is part of the Pacific “Ring of Fire,” an arc of earthquake and volcanic zones stretching from South America through Alaska and down through the South Pacific. Read more…

Sunspots spawn solar flares that can cause billions of dollars in damage to satellites, communications networks and power grids.

But Stanford researchers have developed a way to detect incipient sunspots as deep as 65,000 kilometers inside the sun, providing up to two days’ advance warning of a damaging solar flare.

Viewed from the technological perspective of modern humans, the sun is a seething Read more…

Three young Americans have died this year from a rare water-borne amoeba that swims up through the nose and infects the brain, the Centre for Disease Control (CDC) said.

Naegleria fowleri – an amoeba found in warm freshwater lakes and rivers and occasionally in poorly treated swimming pools – causes a “rare, but severe” brain infection and kills around three people a year, the CDC said.

In the first week the disease causes major headaches, fever, vomiting and a stiffening of the neck, eventually leading to confusion, seizures and Read more…

In a bid to track future sea-level increases from climate change, researchers at NASA have come out with the first complete map of the speed and direction of ice flow in Antarctica.

The map, which was created by using integrated radar observations from a grouping of international satellites, shows glaciers flowing thousands of miles from the continent’s deep interior to its shore.

NASA-funded researchers at the University of California (UC), Irvine, used billions of high-resolution radar data points of the continent’s ice flows provided by European, Japanese and Canadian satellites between 2007 and 2009 to extract the clouds, solar glare and land features covering the glaciers.

The researcher’s team, with the help of NASA technology, carefully joined the shape and velocity of glacial formations. The map even includes Eastern Antarctica – an area that, while comprising Read more…

HANOI Vietnam is battling to control an unusually severe outbreak of Hand, Foot and Mouth Disease (HFMD) that has killed 81 children this year and infected tens of thousands more, health officials said on Thursday.

About three-quarters of the more than 30,000 reported HFMD cases so far this year have occurred in children younger than three, said Graham Harrison, the World Health Organisation’s acting representative for Vietnam.

“It’s a challenge to deal with it,” he said. “It’s certainly a significant increase on the previous two or three years.”

All of the dead were children, Vietnam’s health ministry said.

HFMD is a common viral illness of infants and children that causes fever and blister-like eruptions in the mouth, according to the US-based Centres for Disease Control and Prevention, which are Read more…

The T-50 resembles Russia’s best-selling Su-30 fighter jet but will have all its weapons hidden inside its body and wings to avoid radar detection and will fly at supersonic cruising speeds. The aircraft will also boast ultra manoeuvrability and high-technology avionics.

The Russian Air Force will begin testing the Perspective Frontline Aviation Complex, as the plane is called in Russia, in 2013 and will start inducting its mass-produced version from 2014, said the Russian Air Read more…
