Enhancing earthquake early warning in the Pacific Northwest

Earthquake Early Warning (EEW) systems depend on speed and accuracy in delivering seismic monitoring data to areas at risk from a quake or volcanic eruption. Paul Bodin of the University of Washington and colleagues have been testing models of EEW systems within the Pacific Northwest Seismic Network (PNSN) in Washington State and Oregon to learn more about what factors could be improved to provide the most timely warnings for their region. For instance, what's priorities are important for getting a speedy warning to those at risk: the placement of seismic monitoring stations, or the number of stations, or the speed at which data can be transmitted between stations and notification centers?
