EARTH: Vital Seconds - The Journey Toward Earthquake Early Warning for All

Submitted by mmoses on

Earthquake early warning (EEW) is exactly what it says: It is an early warning that shaking is coming and it can typically give a few seconds to a few minutes, at most, of warning. The warnings can be sent off just after an earthquake occurs on a fault, but before the damaging secondary waves are felt. In the October cover story, EARTH Magazine explores the development of EEW systems in California, Oregon and Washington. Learn about how EEW systems work, who gets to beta test them, and how the scientists and engineers are navigating the waters of the public policy-science interface.

Interactive map of fault activity in California

The California Geological Survey's interactive map allows users to identify the location and classification of faults throughout California. Information available includes the age of the most recent activity on each fault segment, surface rupture areas, and whether or not the faults are visible at the surface.

Interactive map of natural hazards worldwide

The National Oceanic and Atmospheric Administration's natural hazards viewer shows a variety of recent and historic natural hazards around the world. The interactive map provides data for a range of natural hazards, including tsunamis, volcanic eruptions, and earthquakes. Users can select individual hazards to learn more about the date of occurrence, location, severity, economic impact, and social impact.

Interactive map of Pennsylvania's geology and natural resources

The Pennsylvania Geological Survey's PaGEODE online tool provides an interactive map of the geology and natural resources of Pennsylvania, including:

  • Surface and bedrock geology
  • Earthquakes
  • Karst features
  • Coal, oil, and gas resources
  • Sites of notable geologic interest
  • Street and topographic maps, and aerial images

The map allows users to select multiple layers that can be overlain on each other. By doing this, users can see how different features are related.

Interactive map of geohazards in Oregon

The Oregon Department of Geology and Mineral Industries statewide geohazard viewer, HazVu, provides a way to view a range of geohazards in the state of Oregon,including:

  • Earthquakes - active faults, historical epicenters, expected shaking, and liquefaction hazards
  • Tsunami inundation hazard
  • Volcanoes
  • Landslides - historical landslides and landslide susceptibility
  • Floods
  • Coastal erosion

The map also includes public buildings so that hazards can be assessed for these locations.

Interactive map of earthquakes in Ohio

The Ohio Department of Natural Resources Division of Geological Survey provides an interactive map of earthquake epicenters and magnitudes for past earthquakes in Ohio. For each earthquake, users can click on the symbol to find out specific information and access a full earthquake report. The map also uses star icons to indicate the location of seismic stations throughout Ohio. By clicking on the star icon, users can learn more about where the seismic station is housed and who the designated contact is for each station.
