Crowdsourced earthquake early warning
Earthquake early warning (EEW) can reduce harm to people and infrastructure from earthquakes and tsunamis, but it has not been implemented in most high earthquake-risk regions because of prohibitive cost. Common consumer devices such as smartphones contain low-cost versions of the sensors used in EEW. Although less accurate than scientific-grade instruments, these sensors are globally ubiquitou...
متن کاملModel-based Development of Self-organising Earthquake Early Warning Systems
A new approach for Earthquake Early Warning Systems (EEWS) is presented that uses wireless, self-organising mesh sensor networks. To develop the prototype of such IT-infrastructures, we follow a model-driven system development paradigm. Structure and behaviour models of network topologies in specific geographic regions are coupled with wave signal analysing algorithms, alarming protocols, conve...

متن کاملAutomatic earthquake confirmation for early warning system
Earthquake early warning studies are shifting real-time seismology in earthquake science. They provide methods to rapidly assess earthquakes to predict damaging ground shaking. Preventing false alarms from these systems is key. Here we developed a simple, robust algorithm, Authorizing GRound shaking for Earthquake Early warning Systems (AGREEs), to reduce falsely issued alarms. This is a networ...
متن کاملDecision criteria for Earthquake Early Warning applications
The recent large earthquakes have emphasized the importance of earthquake loss mitigation and how earthquake early warning (EEW) systems can help. An EEW system detects an earthquake initiation based on a seismic sensor network and broadcasts a warning of the predicted location and magnitude shortly before an earthquake hits a site. The typical range of this lead time is around tens of seconds ...
