Earthquake outlook for the San Francisco Bay region 2014–2043

Using information from recent earthquakes, improved mapping of active faults, and a new model for estimating earthquake probabilities, the 2014 Working Group on California Earthquake Probabilities updated the 30-year earthquake forecast for California. They concluded that there is a 72 percent probability (or likelihood) of at least one earthquake of magnitude 6.7 or greater striking somewhere in

HayWired aftershock (M> 5) ShakeMaps

The maps in this archive display estimated intensities and ground motions for the largest earthquakes in the HayWired aftershock sequence. The aftershock sequence follows the HayWired M7.0 mainshock that is imagined to occur on April 18, 2018 along the Hayward Fault.These maps have been used in analyses of the HayWired scenario.

Ground motion and regional information of the M 7.0 mainshock

The HayWired scenario depicts a hypothetical M7.0 earthquake on California’s Hayward Fault. This site includes an interactive map showing fault traces and ShakeMap contours, information on the tectonic setting of the Hayward Fault and fault rupture history; and a USGS ShakeMap, which provides ground motion information for the HayWired scenario mainshock.

CoSMoS Implementation versions

The Coastal Storm Modeling System (CoSMoS) makes detailed predictions (meter-scale) over large geographic scales (100s of kilometers) of storm-induced coastal flooding and erosion for both current and future SLR scenarios, as well as long-term shoreline change and cliff retreat. Several versions of CoSMoS have been implemented for areas of the California coast, as shown on this map.

The HayWired Scenario: An Urban Earthquake in a Connected World - A Geonarrative

What might it be like the next time the Hayward Fault has a large earthquake? A geonarrative and related imagery examines a hypothetical earthquake, the magnitude 7.0 HayWired earthquake scenario.

Hurricane Maria's Water Footprint

Hurricane Maria made landfall in Puerto Rico on September 20, 2017, bringing with it a mix of high winds and extreme rainfall. Much of the island experienced flooding and structural damage along with a loss of electricity and water.
