Beijing - Chinese authorities warned Thursday of more travel misery to come as millions of people struggled to get home for China's most important holiday amid savage winter weather.
Across the country, millions of travellers have been stranded or delayed in the transport chaos wreaked by freezing conditions and the worst winter snow storms in 50 years.

Buffalo, N.Y. - Lake Erie surged over its eastern shore Wednesday, adding flooding to the headaches delivered by a windy storm that tipped tractor-trailers, disrupted flights, and toppled trees and power lines across a wide swath of the nation.
Earthquakes occurring at the edges of tectonic plates can trigger events at a distance and much later in time, according to a team of researchers reporting in today's (Jan. 31) issue of Nature. These doublet earthquakes may hold an underestimated hazard, but may also shed light on earthquake dynamics.
"The last great outer rise earthquakes that occurred were in the 1930s and 1970s," said Charles J. Ammon, associate professor of geoscience, Penn State. "We did not then have the equipment to record the details of those events." The outer rise is the region seaward of the deep-sea trench that marks the top of the plate boundary
In late 2006 and early 2007, two large earthquakes occurred near Japan separated by about 60 days. These earthquakes took place in the area of the Kuril Islands that are located from the westernmost point of the Japanese Island of Hokkaido to the southern tip of the Kamchatka Peninsula. The first event took place on Nov. 15, 2006 when the edge of the Pacific plate thrust under the arc of the Kuril Islands, initiating a magnitude 8.3 event and causing some damage in Japan and a small tsunami that caused minor damage in Crescent City, California. About 60 days later, on Jan. 13, 2007, a magnitude 8.1 earthquake occurred in "the upper portion of the Pacific plate, producing one of the largest recorded shallow extensional earthquakes."

Tropical Cyclone Gene, which battered the South Pacific island nation of Fiji killing at least seven, has moved west towards the southern Vanuatu island, local media said Wednesday.
Winds gusting up to 150 k/ph (93 m/ph) hit Fiji's main islands of Viti Levu and Vanua Levu, causing floods, blackouts and damage to homes and buildings.
Two people were electrocuted by collapsed power lines and another man died in a house fire, while others were killed by the storm.

Aggression, testosterone and nepotism don't necessarily help one climb the social ladder, but the support of a good female can, according to new research on the social habits of an unusual African species of fish.
The study, published today in the journal Proceedings of the Royal Society, highlights the complex relationship between social status, reproductive physiology and group dynamics.
"We found that changes in social status were regulated by the most dominant female in a social group," says John Fitzpatrick, lead researcher and a graduate student in the Department of Biology at McMaster University. "In fact, dominant females seemed to act as gatekeepers, allowing only males larger than themselves to move up in status and become dominant."

A heavy snowfall blanketed Jerusalem and the surrounding areas Tuesday night and was continuing to fall Wednesday. As expected, the Jerusalem Municipality decided to cancel school in the capital for the day due to the slippery streets. University classes were also canceled, as well as kindergartens and preschools. There were also no classes in Gush Etzion, Ofra, Kochav Ya'acov, Tel Zion, Ma'ale Levona, Eli, Shilo and Beit El.

New information is leading to a controversial shift in thinking on the impact of global warming on ocean circulation, partly due to the work of a UA researcher.
Athens - An 5.0 magnitude quake shook Greece on Tuesday without causing injuries or damages.
"The epicentre of the earthquake was 50 km south of Athens, in waters off the coast of the island of Aegina," an Athens Geodynamic Institute official said. It was also felt in the capital Athens.
There were no immediate reports of injuries or damages, the fire department said.

DENVER - A powerful storm system raced across the nation Tuesday, spawning everything from heavy snow and numbing cold to thunderstorms and possible tornadoes, and forecasters warned more bad weather was on the way.
High winds associated with thunderstorms may have killed two people in Indiana, authorities said. Snow forced the closure of schools and highways in many areas, and avalanche warnings were issued for some Western regions.

QUITO -- Volcano Tungurahua in central Ecuador has remained highly active in more than three weeks after it first began showering the nearby region with ash, the National Polytechnic's Geophysics Institute said in a statement Monday.
The 5,029-km mountain emitted a new burst of gas and columns of smoke earlier Monday, extending its increased activity starting on Jan. 5.
In 2006, the volcano killed six people and destroyed thousands of hectares of crops during eruptions of hot ash that lasted through July and August.
