  Study

The Seattle fault zone is a network of shallow faults slicing through the lowlands of Puget Sound, threatening to create damaging earthquakes for the more than four million people who live there. A new origin story, proposed by Washington State Department of Natural Resources geophysicist Megan Anderson and others in a new study, could explain the fault system’s earliest history and help scientists improve hazard modeling for the densely populated region.

Supervolcano Eruptions More Likely, as they can be Triggered by Melt Buoyancy

A graph showing the relationship between eruption volume and time between eruptions, using the models presented in Carrichi and others (2014). Notice how for buoyancy-driven eruptions (in blue), the time between eruptions doesn’t vary much across a wide range of volumes. Image: Figure 3 from Caricchi and others (2014), Nature Geoscience.

Washingtons ‘Shake Alert’ Earthquake Warning System Would Need $17M Annually

According to UW’s John Vidale, as reported by KING-TV and The Seattle Times, getting an early warning system in place for WA would cost some $17 million annually.
