Japan Quake Seismograph Trace

My name is Mike Cluster in Lynnwood. I saved a screenshot I made from a local seismograph trace of the Japan quake activity last night, including aftershocks. The Pacific Northwest Seismic Network (PNSN) station northeast of Maltby towards Monroe did a very good job of recording the local quake resonance. Each horizontal line represents 10 minutes out of a 6-hour stretch, spanning from the upper left to lower right.
Here is a link to the real-time current trace of that station:

will the radioative plume releaced from Japans reactors be caught up by wind currents coming this way.

If there is a meltdown in Japan, the radio activity can be released and travel by prevailing winds in the directon of N. America. I wonder if anyone is thinking about this and should not precautions be broadcast for all concerned.

Thanks Mike, and thanks to the PNSN. They have been one of my 'favorites' for a long time. I enjoy seeing the Mt St Helens and cascade range activities there.

Experts say it's very unlikely that any radiation released into the atmosphere in Japan would reach the U.S. in harmful concentrations.

The experts are wrong. It's already here.
