Ash Getting Worse! Flights Grounded Through Saturday
The UK has now grounded aircraft through 1AM GMT Sunday. The ash cloud has gotten worse and there is a new plume headed toward Europe as the image above indicates. Meteorologists from the Iceland Met Office flew o Friday near the volcano to check the height of the ash cloud and reported it is nearly 30,000 feet (10,000 meters). The upper level winds at this level will steer the ash …

A Selection of Good Science Online This Week
There are some fabulously well written blogs and excellent science sites online. I have never done a post of the best that I have come across before, until now! So below is a sampling of sound science writing that got my attention this week. I love astronomical time lapses and Amanda Bauer in the UK has a great one. Tavie Greiner and Rob Keown have a post on International Sidewalk …

Large aftershocks are already being recorded. The quake hit when most people were in bed asleep. The USGS says this quake occurred 230 km north of the location of the 9.5 quake of May 1960. That quake holds the record for the …

Rumblings on Rainier??
I did a geological field trip to the Pacific Northwest in 2006. It was two fabulous weeks and I got some great snaps of beautiful Mount Rainier. This past Summer, while at the American Meteorological Conference in Portland, I returned to Mount Saint Helen’s as well. When St. Helen’s exploded in May 1980, the volcanic dust was tracked on satellite imagery across the country. I had only been doing weather …
