Earth Changes
Ice-covered streets were deserted in Super Bowl host city Dallas. Whiteouts shut down Oklahoma City and Tulsa. And more was on the way. Chicago expected 2 feet of snow, Indianapolis an inch of ice, and the Northeast still more ice and snow in what's shaping up to be a record winter for the region.
The system that stretched more than 2,000 miles across a third of the country promised to leave in its aftermath a chilly cloak of teeth-chattering cold, with temperatures in the single digits or lower.
Winds topped 60 mph in Texas. The newspaper in Tulsa, Okla., canceled its print edition for the first time in more than a century. In Chicago, public schools called a snow day for the first time in 12 years, and both major airports gave up on flying until at least Wednesday afternoon.
Researchers call this a "coronal hole." Solar rotation is turning the coronal hole toward Earth. The stream of solar wind pouring from it will swing around and hit our planet in early February, possibly sparking polar magnetic storms. High-latitude sky watchers should be alert for auroras between Feb. 2nd and 4th.
The U.S. Geological Survey says a temblor with a magnitude of 3.0 struck early Tuesday about 25 miles northwest of the ghost town of Jeffrey City.
The quake comes almost a week after another minor earthquake struck Wright. A 3.2 magnitude earthquake struck at 10:16 p.m. Thursday. It happened just 7 miles northeast of Wright, about 5 miles underground.
At first the USGS thought it might be a mine blast, but later deemed it a genuine earthquake.
David King, Campbell County's emergency management coordinator, said the county sits on several fault lines which have caused 10 recorded earthquakes since 1967.
Thursday's quake is the county's fourth quake since 2000. Quakes in 2009, 2008 and 2004 all occurred about 17 miles underground away from Gillette at a magnitude of about 2.5.
The county's largest earthquake occurred in September 1984 west of Gillette by the Johnson County line at a magnitude of 5.1. There were two other earthquakes in the county that year - a magnitude 5 and 2.5.
There are no recorded earthquakes in Gillette.
The U.S. Geological Survey reports a quake with a magnitude of 3.1 was detected Tuesday at 4:25 a.m. in rugged, mountainous terrain 29 miles west of Salmon near the former mining town of Cobalt.
The quake was first detected by staff at the Earthquake Studies Office at the Montana Bureau of Mines and Geology. Director Mike Stickney says a 3.1 magnitude is barely enough to cause people to notice and it's not likely the tremor caused any serious damage to the landscape.
Stickney says it's not uncommon for small quakes to jolt the vast, mountainous backcountry north of Salmon and Challis.
The weather bureau says Cyclone Yasi is a large and very powerful tropical cyclone and poses an "extremely serious threat" to life and property within the warning area, especially between Port Douglas and Townsville.
"This impact is likely to be more life-threatening than any experienced during recent generations," the Bureau of Meteorology (BOM) said this morning.
Tens of thousands of people are fleeing their homes ahead of the monster storm, which is expected to hit the coast between Cairns and Innisfail some time tonight.
This morning it was estimated to be 650 kilometres east north-east of Cairns and 650 kilometres north-east of Townsville, moving west south-west at 30 kilometres per hour.
"There's still potential for it to become stronger ... as a strong category five we could see wind gusts in excess of 320 kilometres an hour (200mph). Which is just horrific."
NASA's Aqua and Terra satellites have been providing visible, infrared and microwave looks at the storm system's clouds, precipitation, temperatures and extent.
Steve Irwin works for "Island Marine Services" based in Fort Pierce.
He said he was flying about 100 yards off of Palm Beach, at 80 mph, when he spotted thousands of sharks, according to TV station WPTV.
Irwin recorded the migrating sharks on his iPhone.

A dome of lava grows larger inside the crater of Mount Shinmoedake in the Kirishimna range on Japan's southernmost main island of Kyushu Monday, Jan. 31, 2011. Officials urged more than 1,000 residents to seek safer ground on Monday and expanded a no-access zone around the 4,662-foot (1,421-meter) volcano that has exploded back to life. The volcano erupted last week for the first time in 52 years.
The danger zone around Shinmoedake volcano was widened to keep residents safe. The largest eruption since it burst back to life last week covered wide areas in ash, shot boulders onto distant roads, knocked down trees and broke hundreds of windows in hotels and offices.
No serious injuries have been reported since the initial eruption last Wednesday, but public broadcaster NHK said a woman suffered cuts from shattered glass in Tuesday's blast.
NHK said the eruption was five times larger than the initial activity last week, which was Shinmoedake's first major eruption in 52 years.
Japan's Meteorological Agency has restricted access to the mountain, and on Tuesday broadened the no-go zone to anywhere within a 2 1/2-mile (four-kilometer) radius of the crater. Two lodges and scattered homes are within the perimeter.
Dozens of domestic flights in and out of Miyazaki - about 590 miles (950 kilometers) southwest of Tokyo - were grounded last week and more cancellations followed. Train service was temporarily suspended in the area and many schools closed.
The local government also reported damages to crops.
