According to Bill Steele, the public is woefully unprepared for a certain disaster: we just don’t know when. Mr. Steele is Seismology Lab Coordinator for the Pacific Northwest Seismograph Network (PNSN) at the University of Washington Department of Earth and Space Sciences where he has worked since 1993.
Every 500-1000 years the slopes of Mount Rainier produce liquefied mud flows called lahars that can flow like rivers but have a density similar to liquid concrete. Based on the last Electron Mudflow ~550 years ago, and using HAZUS software, the DNR released a new report that estimates potential damage to property (but not life) based on these lahars for the first time.
The University of Washington Seismology Lab, has released a new map of major semi-recent quakes and fault lines around Puget Sound.
