ShakeAlert ® is a distributed system, enabling the independent development of individual components. It has also been designed to use multiple algorithms, whose information is combined to provide single alerts to end users. This framework facilitates ongoing development and updates of the system, as new research is conducted and methods developed. Scientists at Caltech have […]
Starting in 2007, Caltech has been part of a multi-institutional collaboration of scientists and engineers to create a US-based earthquake early warning (EEW) system. Working with USGS Pasadena, UC Berkeley, ETH and USC/SCEC , the effort includes the development and implementation of the demonstration system for California deployed in 2012, called ShakeAlert® (Böse et al., 2012). ShakeAlert® makes […]
Three algorithms for rapidly detecting the start of an earthquake have been developed and will be improved and integrated into the ShakeAlert® System: ElarmS – ElarmS, or Earthquake Alarm Systems, detects the initial energy to radiate from an earthquake, the P-wave energy, which rarely causes and damage. Using the arrival time of the P-wave at the […]
