The Celebrity Examiner and Oregon Public Broadcasting have brief stories on the ongoing swarm just south of the Oregon-Nevada border. Even though this swarm is officially in Nevada's reporting region earthquakes in it are reported on the PNSN earthquake map and show up on many PNSN seismic stations in the area.
Here are the news releases on Nevada swarm from Oregon Department of Geology and Mineral Industries and Nevada Seismological Laboratory at University of Nevada, Reno.

MarketPlace news has a report on the "controversy" between a private version of EEW and the US Geological Survey sponsored version (in which the PNSN is participating).

The Seattle Times has a very good discussion of the different interpretations of deep-sea geologic evidence for the frequency and size of our big earthquakes. There is no question that they occur, just what some of the evidence for their frequency means. A more garbled view of the controversy was in the science journal, Nature, last week.

The iMUSH active experiment will start this Tuesday (Jul 22) night with a number of explosions being set off in boreholes in the general Mount St. Helens area. The PNSN is making available realtime seismic data from our stations for iMUSH scientists (and anyone) to monitor these shots as they occur. See the iMUSH blog entry for these realtime recordings.
