Lake Superior frozen over in cold winter

Hancock - There hasn't been much snowfall in the Houghton/Hancock area recently, and according to Steve Fleegel, that's due in large part to the condition of Lake Superior.

"It's pretty much frozen over," said Fleegel, who is a meteorologist at the National Weather Service office in Negaunee Township. "There's a few little breaks here and there."

Because the lake is frozen, Fleegel said when cold air passes over it, lake effect snow isn't created as when the relatively warmer water is open.

Despite the colder-than-normal December and January, Fleegel said there was an area of open water east of Marquette. After the colder-than-normal temperatures in the last week of February and so far in March, that area finally froze over.

"(December and January) kind of set the stage," Fleegel said.

Comment: Three of the Great Lakes are frozen over. While this happens once or twice a decade it is still shows the strength of this current winter's severe cold.

US: Blizzard Coming Early Next Week

The eastern half of the country is experiencing warmer than normal temperatures, and there will not be any snow the next 24-36 hours east of the Mississippi River. The exception is northern New England where there can be just a few snow showers Friday night.

It will be a wild scene for sure. And let's not forget the potential for a large outbreak of severe thunderstorms through the Mississippi River Valley.

UK: Commuter chaos as forecasters caught out by heavy snowfall

Snow Britain March 2009

A worse-than-predicted shower of snow left motorists stranded in parts of South West England today, while heavy frost caused commuter chaos in the South.

Forecasters admitted being caught unawares after up to 3in (8cm) of snow landed overnight near Okehampton, in Devon, while parts of Somerset and West Dorset also experienced heavy flurries.

However, the travel chaos spread beyond the areas affected by snow this morning, with several train services from the south coast to London being suspended, disrupted or cancelled due after heavy frost froze power lines.

In the West, forecasters admitted being taken by surprise by the suddenness of the snowfalls affecting the region, which led to drivers being stranded for an hour near Okehampton while the main A30 road was cleared, and other parts of Somerset - in particular Taunton - and West Dorset also being hit.

Volcano Erupts in Indonesia

The tallest volcano on Indonesia's Java island erupted on Friday, spewing smoke and ash high into the sky and coating a nearby town in black dust, an official said.

The 3,676-metre Mount Semeru burst into life shortly after midnight but officials said it posed no danger to people living in the area, 35 kilometres southeast of Lumajang.

'We recorded that it erupted after midnight on Friday but luckily we have had rains so the ash isn't causing serious respiration problems for the residents,' volcanologist Agus Budianto told AFP.

4.7 Earth Tremor Shakes Melbourne, Australia

Residents across Melbourne have been rattled by an earth tremor that struck about 100km south-east of the city.

The United States Geological Survey reported on its website the tremor measured 4.7 on the Richter scale, about 96 kilometres from Melbourne, and Geoscience Australia says the tremor was centred near Korumburra.

There have been no reports of injury and police are urging people not to call 000 unless they have been injured or suffered property damage.

Victoria Police and the State Emergency Service also say there has been an earth tremor but said there are no reports of any damage so far.

California: 3.1 Earthquake Recorded in Geysers

An earthquake was felt on Cobb Mountain Thursday afternoon.

The quake, measuring 3.1 on the Richter scale, occurred at 3:06 p.m., according to the US Geological Survey.

It was centered two miles north northeast of The Geysers, three miles west of Cobb and six miles northwest of Anderson Springs, the US Geological Survey reported. It occurred at a depth of three-tenths of a mile.

Residents of Cobb, Middletown and even distant Fresno reported to the US Geological Survey that they felt the quake.

Chilean extremophile bacteria thrive in Mars-like conditions

The Atacama desert lies on the western edge of South America, covering much of northern Chile and parts of Argentina. It is the closest one can get to Mars while remaining grounded on Earth. High atop the Socompa volcano on the Eastern edge of the Atacama desert, the atmosphere is thin, the ultraviolet radiation is intense, and the climate is dry. Nevertheless, the improbable has been found: life. Near the rim of the 19,850-foot-high Socompa volcano, researchers from the University of Colorado at Boulder's Alpine Microbial Observatory found a thriving, complex microbial community that appears to be supported by gases emanating from volcanic vents around the rim.

Alaska: Okmok Volcano warning level raised to yellow

Unalaska - The Alaska Volcano Observatory raised the warning level for Okmok to yellow, or advisory, on Monday after a series of seismic bursts that lasted for six hours. The tremors repeated again Wednesday but have since subsided. AVO coordinating scientist Steve McNutt said these seismic signals could mean anything.

"Signals like this sometimes precede eruptions on the scale of hours to days, sometimes weeks or longer. And then sometimes the volcano just goes back to sleep," he said. "So you have to be cautious and assume that it may erupt and it could do so quickly, so that's the basis for our treating it with caution and changing the color code. On the other hand it could represent a new physical state of the volcano in which case it could do something different and then go back to sleep."
