Real-time Earthquake Products

• Aftershock Forecasts
  Forecasts are posted for earthquakes of M5+ in the United States and U.S. territories to provide situational awareness of the expected number of aftershocks.
   
• Did You Feel It?
  DYFI is a citizen science web application that invites users to answer a questionnaire about their experience of an earthquake, and then creates a map of the felt shaking (macro seismic intensity) with all the information collected.
   
• Early Warning/ShakeAlert®
  The ShakeAlert® earthquake early warning system monitors for significant earthquakes and issues alerts to warn that strong shaking is expected imminently.
   
• Earthquake Notification Service (ENS)
  The Earthquake Notification Service (ENS) is a free service that can send you automated notification emails when earthquakes happen in your area.
   
• Finite Faults
  Rapid finite-fault determination and source modeling waveform (WF), InSAR and real-time GPS modeling.
   
• Ground Failure
  Near-realtime spatial estimates of earthquake-triggered landslide and liquefaction hazard following significant earthquakes worldwide.
   
• Moment Tensors
  Automated computation of source duration and source-time function for all M6+ earthquakes.
   
• PAGER
  PAGER rapidly assesses the overall impact (casualties and losses) for all damaging earthquakes within minutes of the earthquake.
   
• ShakeMap
  ShakeMap is an emergency response tool designed to rapidly portray the extent and degree of damaging ground motions recorded in a seismic network.
   
• ShakeCast
  An application for automating ShakeMap delivery to critical users and for facilitating notification of shaking levels at user-selected facilities.
