The reason that we have active volcanos is that the Jaun de Fuca plate is going under the North America Plate. The earthquake should be like the one in Japan, a 9. We have no idea of the timing and how urgent it is, Goldfinger tells Pop Mech. In the NW we are way overdue for a slip on the Cascadia Subduction Zone.
The animation with related resources can be found on the UNAVCO site. It’s certain that the Northwest will experience a devastating earthquake again, says Chris Goldfinger, an oceanographer at Oregon State University and one of the world’s leading experts on subduction zone earthquakes. Americans have long dreaded the Big One, a magnitude 8.0 earthquake along. This animation was made by UNAVCO in collaboration with the Cascadia EarthScope Earthquake & Tsunami Education Program CEETEP and IRIS. Can the Pacific Northwest prepare for the cataclysmic quake thats coming. The Pacific Northwest Seismic Network seeks to reduce risk within the states of Washington and Oregon by: monitoring ground motions within the region in order to better understand earthquake and volcano hazards and their impacts on the physical, economic, political, and social environment, providing the most accurate information about. In this animation we can see how ground motion, measured by GPS, can enhance earthquake early warning. But for earthquakes greater than magnitude 7, that small patch at the epicenter is just the starting point for a rupture that spreads over a huge area as it tears the fault and radiates immense seismic energy. In its simplest form, an earthquake early-warning system assumes the earthquake results from sudden slip on a small area of a fault surface, and the initial magnitude represents that motion. Data from the 2011 Tohoku, Japan earthquake taught us much about mega-thrust earthquakes. This is not the same as earthquake prediction. Computers, communications technology, and alarms are devised to notify the public while an earthquake is in progress. How does an earthquake early warning system work?Īn earthquake warning system uses existing seismic networks to detect moderate to large earthquakes.
The PNSN collects and studies ground motions from about 400 seismometers in the states of Oregon and Washington. Your browser does not support the video tag. The damage and deaths in the 1965 earthquake were tragic, but they helped bring about the installation of the Pacific Northwest Seismic Network in 1969.
