SRL Publishes Focus Section on Machine Learning

1 March 2019–With a growing wealth of seismic data and computing power at their disposal, seismologists are increasingly turning to a discipline called machine learning to better understand and predict complicated patterns in earthquake activity. In a focus section published in the journal Seismological Research Letters, researchers describe how they … Continue Reading »

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 »

At Work: Vedran Lekic

When an earthquake occurs, seismic waves travel throughout the Earth. As they encounter material of different rigidity, however, they slow down or change direction. By mapping out where this happens, scientists can create images of the structures and processes within the deep Earth – a technique known as global tomography. … Continue Reading »
