US: Moderate Quake Hits Silicon Valley; No Reports of Damage

A moderate earthquake rattled parts of Silicon Valley Monday, but there were no immediate reports of damage.

The U.S. Geological Survey said the temblor had a preliminary magnitude of 4.3 and struck at about 10:40 a.m. PDT. It was centered 11 miles north of the city of Morgan Hill, or about 16 miles southeast of San Jose.


Strong 6.0 earthquake hits Indonesia: USGS

A strong 6.0-magnitude earthquake shook Indonesia's Papua region early Sunday, the US Geological Survey said.

The quake, which hit at 2:59 am (1759 GMT Saturday), was centred 135 kilometres (85 miles) southwest of the Papuan provincial capital of Jayapura at a depth of 53 kilometres, the USGS was quoted by AFP as saying.

There were no immediate reports of casualties or damage.

The Indonesian archipelago sits on the so-called Pacific Ring of Fire where continental plates meet, causing frequent seismic and volcanic activity.


Gorging on omega-3 fats lets birds get fit without exercise: study

Bobwhite quails are typically poor fliers and "not really endurance athletes at all," said researcher Jean-Michel Weber.
It's a pity you're not a quail. Ottawa researchers have found that quails can boost their aerobic fitness just by sitting around and eating fats, provided they're the right kind.

The right kind happens to be omega-3 fatty acids, the same fats shown to reduce the risk of cardiovascular disease and lower blood pressure in humans.

After sedentary bobwhite quails were fed a supplement of omega-3 fatty acids for six weeks, their muscles showed a huge boost in the activity of enzymes that improve endurance compared to quails that didn't get the supplement, said a research paper published Friday in the Journal of Experimental Biology.

The same enzymes get more active and improve endurance in human athletes who train very hard for weeks, said University of Ottawa biologist Jean-Michel Weber, who conducted the study with his student Simba Nagahuedi.


US: Urban coyote attacks on rise, alarming residents

This is an undated file photograph taken in November of 2008 of a pair of coyotes roaming through a housing subdivision in the south Denver suburb of Littleton, Colo., that was taken by a member of the Colorado Division of Wildlife. After a handful of recent attacks by coyotes in suburban Denver enclaves, officials are trying to keep the animals away from residents.
Denver - A coyote ambling into a Chicago sandwich shop or taking up residence in New York's Central Park understandably creates a stir. But even here on the high plains of Colorado, where the animals are part of the landscape and figure prominently in Western lore, people are being taken aback by rising coyote encounters.

Thanks to suburban sprawl and a growth in numbers of both people and animals, a rash of coyote encounters has alarmed residents.

Wildlife officials are working to educate the public: Coyotes have always been here, they've adapted to urban landscapes and they prefer to avoid humans.

"Ninety-five percent of this problem is a human problem, and we really need to focus on that 95 percent to solve it," said Nicole Rosmarino, wildlife program director of the environmental group WildEarth Guardians.

Earthquake rattles northern Peru

A moderate earthquake has occurred near the city of Piura in northern Peru but there were no immediate reports of casualties or damage.

The magnitude 5.8 quake struck at 1235 local time (1735 GMT), 85km (55 miles) to the south-west of the city of about 400,000 people.

The US Geological Survey estimated its depth to be 15.6km (9.7 miles).


Strong earthquake strikes off Japan

A strong 6.0-magnitude earthquake has struck off Japan's southern island of Okinawa, the US Geological Survey says.

The quake struck at 4:19am (local time), 165 kilometres north-west of Okinawa's capital Naha at a depth of 138 kilometres.

There were no immediate reports of casualties or damage.

About 20 per cent of the world's most powerful earthquakes strike Japan.


Another volcano in Alaska erupts?

This time it appears to be Mount Gareloi. Something big is going on there seismically. The webicorder is going nuts.

Update: I double checked the webicorder to see if it was still operating, and it appears to be. Still no word on the AVO website about the status of Gareloi.

Major Eruptions Continue at Mt. Redoubt

Alaska's Mount Redoubt continued its volcanic explosions Friday, sending ash clouds as high as 60,000 feet above sea level and prompting drivers to head to the auto parts store for new air filters. The National Weather Service said most of the ash was expected to fall to the north, but trace amounts of ash from eruptions on Friday and smaller ones overnight could fall on Anchorage itself.

Since the series of eruptions began Sunday night, the volcano has had several (actually closer to a dozen) bursts. One on Thursday sent ash 65,000 feet high. 5 eruptions followed Friday sending ash as high as 51,000 and 60,000 feet. The last time the volcano had erupted was during a four-month period in late 1989 and early 1990.


Drowning in the snows of Kotzebue Alaska

It's March now, how March should be-blue and sunny, twenty to thirty below in the morning with daytime highs rising to zero. Winter is slipping into memory, but we still have the drifts around Kotzebue to remind us.

January brought a longer-than-usual stretch of 30 and 40 below weather. We got restless, on the verge of cabin fever. We thought we deserved a break. Then the storms came, blizzards after blizzard--so often that we might as well have painted our windows white. Not that the paint would have stayed on.

Kotzebue is supposed to be stormy, but this year was more like drowning-we'd get a blow, and if we were lucky have a day to come up for air and shovel out, and then get hit with it again.
