Eruption of 3 volcanoes has scientists asking questions

How likely is it that three neighboring volcanoes would all erupt at the same time -- as the Kasatochi, Okmok and Cleveland volcanoes in the Aleutians did this summer?

About as likely as a storm that only appears once in a thousand years, says Anchorage volcanologist Peter Cervelli, who'll deliver a paper on the subject this winter to the American Geophysical Union.

In other words, seldom enough that Cervelli is now exploring the question of whether Alaska's triple eruption was only a coincidence involving three independent volcanoes or whether it was triggered by some common mechanism.

Trouble In The Pipeline For Grey Whales

The fate of the world's few remaining Western Grey Whales now rests on the outcome of appeals to Russian authorities and courts following the refusal of an oil consortium to consider alternatives to a proposal to lay an oil pipeline through a shallow lagoon crucial to the whales' food supplies.

Last month the Russian government ignored an outcry over project impacts on Piltun Lagoon to grant approval for the pipeline, part of the Sakhalin-1 project which includes oil giant Exxon and Russian, Japanese and Indian oil companies.

Only around 130 Western Gray Whales are left worldwide, including some 20 females able to reproduce. They gather in the seas around Sakhalin in Russia's far east for four months to feed and build up the fat to survive the rest of the year.

Piltun Lagoon produces organic matter crucial for benthos such as as sea stars, oysters, clams, sea cucumbers, brittle stars and sea anemones which form the Grey Whale's main food source.

Hurricane Bears Down on Mexico's Baja California

Hurricane Norbert's winds strengthened to 165 kilometers (105 miles) per hour today as it continued on a track to strike Mexico's Baja California peninsula tomorrow. To the south, Tropical Storm Odile churned up Pacific waters off the Mexican coast.

Norbert, which again became a Category 2 hurricane after weakening yesterday, may produce a storm surge of as high as 1.5 meters (5 feet) when it makes landfall, the U.S. National Hurricane Center said on its Web site. The system was 395 kilometers southwest of Baja California shortly before 5 p.m. Miami time, and moving north at about 17 kph.

Fishing boats are anchored under cloudy skies in Puerto San Carlos' dock as Hurricane Norbert approaches in Mexico's southern Baja California.
Norbert, with winds of up to 105 miles, was expected to hit land along a sparsely populated stretch north of the resort of Cabo San Lucas and then make a second landfall Saturday night in northwestern Mexico's mainland -- possibly as a hurricane, the U.S. National Hurricane Center said.

At least five dead as quake rattles Caucasus

A strong earthquake reverberated through the Caucasus mountains on Saturday, killing at least five people and disrupting power supplies in Russia's Chechnya region, reports said.

The quake, measuring 6.3 on the Richter scale according to Strasbourg observatory estimates, was felt in five regions of the Russian north Caucasus and neighbouring Georgia and Armenia.

The dead were found in Chechnya's east, four of them killed in the Kurchaloy district and the other in Gudermes, said Itar-Tass news agency, citing Chechen vice emergency situations minister, Akhmed Dzheirkhanov.
