US: 15 hurt as storms, possible tornadoes hit Mississippi, Louisiana

Severe storms ripped through central Mississippi, bringing further misery to an area already decimated by a line of tornadoes that killed 12 people in April. Tornado watches were posted across southern Louisiana, much of Mississippi and Alabama and into Tennessee as the storms moved east Tuesday.

Authorities in Mississippi reported 15 people hurt and homes and businesses badly damaged, but no deaths. On Battle Street in Yazoo City, a twister late Monday ripped the tarp off 63-year-old Clarence Taylor's roof, which had been damaged by the April tornado.

"It looks like a war zone now," he said Tuesday morning, pulling a slow drag off a cigarette, then looking around at the power lines dangling from broken poles and pieces of tin scattered about from nearby buildings.

Scientists Fear Mass Extinction as Oceans Choke

Australian scientists fear the planet is on the brink of another mass extinction as ocean dead zones continue to grow in size and number.

More than 400 ocean dead zones - areas so low in oxygen that sea life cannot survive - have been reported by oceanographers around the world between 2000 and 2008.

That is compared with 300 in the 1990s and 120 in the 1980s.

Professor Ove Hoegh-Guldberg, of the ARC Centre of Excellence for Coral Reef Studies (CoECRS) and from the University of Queensland, says there is growing evidence that declining oxygen levels in the ocean have played a major role in at least four of the planet's five mass extinctions.

"Until recently the best hypothesis for them was a meteor strike," he said.

"So 65 million years ago they've got very good evidence ... all the dinosaurs died because of smoke and stuff in the atmosphere from a meteor strike.

"But with the four other mass extinction events, one of the best explanations now is that these periods were preceded by an increase of volcanic activity, and that volcanic activity caused a change in ocean circulation.

Eruption Alert: More Indonesian Volcanoes Getting Restless

As if things weren't already bad enough in Indonesia, another volcano may be about to blow.

Indonesia straddles the Pacific Ring of Fire - and lately, this nation of islands has been living up to the region's fiery reputation. A number of so-called minor ash explosions from Mount Bromo on Sunday (Nov. 28) caused a nearby airport to close as scientists upgraded the volcano to its highest alert level, according to the Indian newspaper The Hindu. On the same island, Java, Mount Merapi's recent eruptions killed hundreds and prompted mass evacuations.

The eruption watch also continues in the straight just west of Java where Anak Krakatau has also been increasingly active lately.

Still want to visit Indonesia? Try virtual tourism.

The heightened eruption alerts come just a couple weeks after Mount Merapi's relentless erupting killed more than 300 people.

Mount Merapi's devastation has been estimated at $611 million and pyroclastic flows have destroyed huge swaths of forest (and one unfortunately placed golf course), according to the People's Daily Online.

US: 21 earthquakes strike Reno over 3 days

An area southwest of downtown Reno has been shaking with earthquakes.

According to the U.S. Geological Survey, 21 temblors were reported in the area since midday Friday.

The latest measured 2.1 in magnitude and was reported at 10:22 a.m. Monday.

The largest measuring 3.0 came at 1:47 a.m. Sunday and was felt throughout the Reno area.

Ken Smith is a seismologist with the University of Nevada, Reno.

He tells the Reno Gazette-Journal that the area of quake activity is about 5 miles west of the intersection of U.S. 395 and the Mount Rose Highway.

In 2008, a cluster of more than 1,000 small earthquakes shook the region for three months before subsiding.

Philippines: 'Explosion-type' earthquake reported at Bulusan Volcano

Legazpi City -- An "explosion-type" earthquake was recorded by the Philippine Institute of Volcanology and Seismology in in Sorsogon Friday night.

In its latest bulletin, Phivolcs said that the quake occurred at around 7:27 p.m. and lasted for about 11 minutes. Clouds, however, prevented state volcanologists to visually observe it.

The statement did not say what distinguished an "explosion-type" earthquake from any other volcanic tremor.

Sulfur dioxide emission rate was measured at 13 tons per day.

About 11 volcanic quakes were also recorded by the seismic network around the volcano during the past 24-hour observation period.

Phivolcs said Bulusan's status remained at alert level 1 and the public was reminded not to venture into the four-kilometer permanent danger zone as sudden steam and ash explosions may occur.

Eyewitnesses Watched as China Earthquake Ripped Ground

The devastating earthquake that hit the heart of China in 2008 caught the region unguarded, and left tens of thousands of people dead.

Because the destruction was so widespread, many people witnessed the ground rip apart, which along with other observations and studies, is helping geologists piece together exactly what happened - and how to prevent future catastrophes.

The area of Wenchuan, China, was crippled by the 7.9-magnitude earthquake that struck on May 12, 2008. The temblor killed more than 70,000 people, injured about 374,000, and left approximately 18,000 missing and presumed dead, according to the U.S. Geological Survey (USGS). More than 45.5 million people across 10 provinces were affected by the quake. Four million people lost their homes. Several cities were almost completely destroyed.

Before the 2008 quake, the region was downgraded to a low seismic risk, so the massive temblor caught many scientists by surprise, which isn't uncommon even in areas known to have frequent earthquakes.

Five Rare Sumatran Elephants Found Dead in Indonesia

Five endangered Sumatran elephants have been found dead in Indonesia, and conservationists said Sunday that they suspect farmers poisoned the animals to stop them from damaging crops.

The elephants - four females and one male all under the age of 5 - were found dead late Friday in Riau province on Sumatra island, said Edi Susanto, a government conservationist.

Susanto suspects that owners of nearby palm oil plantations used cyanide to poison the animals, which are known for damaging crops. He said an investigation is under way and samples from the dead elephants have been sent for analysis.

"We have told the district heads in Riau province to ban farmers from tending crops in the woods where the elephants search for food," Susanto said.

Only 3,000 Sumatran elephants are believed to remain in the wild, a number that dwindles each year with poaching and killing by farmers angry over crop losses.

Temperatures plummeted to the coldest on record for November in parts of the UK overnight.

Northern Ireland reached a new low of -8.6C (17F) at Aldergrove, in Belfast, and in Wales, a record minimum of -18C was recorded at Llysdinam.

Heavy snow is still falling in much of Scotland and north-east England, bringing travel disruption, and is set to last until Tuesday.

Forecasters says Siberian winds from Monday will make it feel even colder.

Met Office severe weather warnings for heavy snow and widespread ice remain in place for eastern Scotland, and north east England, down to Yorkshire and Humber.

Although there will be some sunshine in many parts of the UK, including East Anglia and North Wales later on Sunday, Northumberland, Durham, Nottingham and the Chilterns are set to get further snow showers.

Israel's warm and dry winter: Lack of winter rains even worse than predicted

November set to be worst ever for Kinneret, forecasters predict dry spell to continue into December; cabinet to discuss emergency water plan.

With no significant rainfall thus far, the dire predictions about this winter have become a reality, the Water Authority said on Thursday.

With November nearing its end, Lake Kinneret will likely receive the least water since records started being kept in 1927.

No rain, the lack of humidity, and warm temperatures have increased the evaporation of the lake such that it is losing about half a centimeter a day. It is already a meter below the bottom red line. The lake is expected to break the record set in 2001 for least amount of drinking water available in the month of November.
