What to Expect in a Big Urban Earthquake
A geonarrative (Esri Story Map) that describes what can be expected in a large earthquake in a populated area. Big urban earthquakes are often regional disasters that affect millions of people and livelihoods. The more we know what to expect, the better we can prepare to reduce the impacts of the next one.
The HayWired Scenario: An Urban Earthquake in a Connected World
A geonarrative (Esri Story Map) describing what it might be like the next time the Hayward fault has a large earthquake. Scientists examined a hypothetical earthquake, the magnitude 7.0 HayWired earthquake scenario.
Hayward Fault Field Guide
An interactive geonarrative (Esri Story Map) showing 62 field trip stops for exploring the Hayward Fault in the East San Francisco Bay Region of California.
