Early Warning Alerts for Education
Jennifer Strauss Vice Chair JCCEO ShakeAlertTM earthquake early warning system
Detects significant Once an earthquake is Earthquake alerts allow earthquakes so quickly detected, the expected users and automatic that alerts can reach ground shaking severity systems to initiate actions many people before across a region is to protect themselves, shaking arrives. estimated and alerts are equipment, and delicate sent to local populations operations from injury or before larger more damage during shaking. damaging shaking arrives.
Earthquake 101 The science that makes this possible

• Hundreds of seismometers across the West Coast • Location and magnitude are rapidly estimated by analyzing the first shaking measured by the sensors near the source • Expected ground shaking is estimated and alerts are sent to local populations before larger more damaging shaking arrives P-wave

52 mile rupture 30+ seconds sustained shaking Felt beyond epicenter: EEW Pacific Northwest Seismic Network, California Integrated Seismic Network
• Hundreds of seismometers installed throughout California, Oregon and Washington, along the many faults that can produce earthquakes • ShakeAlert’s sensor network across the three states is only half built-out • Despite being incomplete in some areas, the ShakeAlert network is sufficient for rapid alerting in the LA, SF Bay, Silicon Valley, and the Sea-Tac ar ea.
• Earthquakes are a national problem with 143+ million people exposed to potentially damaging shaking in the U.S. 50 million of those are on the West Coast. • Major earthquakes in the Cascadia Subduction Zone and San Andreas Fault can cause billions of dollars of damage and cost thousands of lives. • Funding provided primarily by the USGS, CalOES, State of Oregon and the GBMF. 2018 station buildout
870 (1675) 52% Complete 1467 by 2020 From earthquake to estimation
• Feb 2016, Production Prototype 1.0 went live in California, sending alerts to beta and pilot users • April 2017 version 1.2 was live throughout the West Coast • Robust redundant system • Data sources, waveform processors, event originators and associators, and an alert generator • Coming soon: V2— pilots going live

Areas close to epicenter in ‘late alert’ zone. Need to get alerts out as quickly as possible. Little existing infrastructure available. Joint Committee for Communication, Education, and Outreach
