Tide Gauges Capture Tremor Episodes in Cascadia

15 February 2019–Hourly water level records collected from tide gauges can be used to measure land uplift caused by episodic tremor and slip of slow earthquakes in the Cascadia Subduction Zone, according to a new report in the Bulletin of the Seismological Society of America. Global Positioning System (GPS) data … Continue Reading »

Toppled Train Offers Insight into 1906 Earthquake

By mathematically modeling the movements of a locomotive that toppled from the tracks north of San Francisco during the city’s infamous 1906 earthquake, researchers have calculated a lower limit on the earthquake ground motion at the spot of the tipped train. Their report in the journal Seismological Research Letters concludes … Continue Reading »
