Method and System for Generating Earthquake Forecasts and Alerts

Summary

Technology Description

 

A basic premise of earthquake science is that earthquakes of significant size are independent of each other in space and time, if aftershocks are excluded. In brief, this technology demonstrates a completely new statistical association between earthquake events, provides a determination of spatially-dependent increases in risk levels following a primary earthquake event, and provides for distribution of alerts accordingly. The method relies on a statistical analysis of an archive of seismological observations to determine the increase in risk for a given locale in response to a primary earthquake event and disseminate an alert.

 

Features & Benefits

  • Improved risk assessment
  • Advance earthquake alerts
  • Quantitative in real time

 

Applications

 

  • Earthquake monitoring
  • Risk assessment
  • Earthquake early warning

 

Background of Invention

 

Earthquakes occur frequently and can cause significant damage and loss of life. Many densely populated areas worldwide are located in or near seismically active regions. Post-earthquake tsunami damage can extend well beyond quake-prone areas. Earthquake prediction has tremendous potential to alleviate both physical damage and loss of life. However, present early warning systems are merely based on the fact that electromagnetic signals propagate much faster than seismic waves, meaning these systems can only warn of an earthquake that is already happening or has already occurred. The amount of warning time at nearby locations is minimal and may be only a few seconds. Accordingly, there remains a significant need for an improved way to quantify earthquake risk before it occurs.
