Early Warning Systems with Real-Time Data

Early Warning Models in Real Time

Each quarter, banks file a call report, or Report of Condition and Income, containing hundreds of accounting items pertaining to their financial condition. Because call reports are filed quarterly, whereas banks are typically examined about once every twelve to eighteen months, statistical early warning models using call report data potentially provide a more up-todate picture of a bank’s condi...

Operational real - time GPS - enhanced earthquake early warning

Moment magnitudes for large earthquakes (Mw ≥7.0) derived in real time from near-field seismic data can be underestimated due to instrument limitations, ground tilting, and saturation of frequency/amplitude-magnitude relationships. Real-time high-rate GPS resolves the buildup of static surface displacements with the S wave arrival (assuming nonsupershear rupture), thus enabling the estimation o...

Real-time Hazard Analysis for Earthquake Early Warning

Earthquake Early Warning Systems (EEWS), based on real-time prediction of ground motion or structural response measures, may play a role in reducing vulnerability and/or exposition of buildings and lifelines. In fact, recently seismologists developed efficient methods for rapid estimation of event features by means of limited information of the P-waves. Then, when an event is occurring, probabi...

Application of real‐time GPS to earthquake early warning

[1] We explore the use of real‐time high‐rate GPS displacement data for earthquake early warning using 1 Hz displacement waveforms from the April 4, 2010, Mw 7.2 El Mayor‐Cucapah earthquake. We compare these data to those provided by the broadband velocity and accelerometer instrumentation of the Southern California Seismic Network. The unique information provided by the GPS‐based displacement ...
