2020-2021 Alaska Peninsula Earthquake Sequence

A summary of the earthquake sequence in the Alaska Peninsula during 2020 and 2021. On 29 July 2021, a magnitude (M) 8.2 earthquake occurred southeast of Perryville, Alaska, (south of the Alaska Peninsula). This event was preceded in 2020 by two nearby earthquakes. The first was a M7.8 earthquake (22 July 2020), followed three months later by a M7.6 earthquake (19 October 2020).

Intermountain West, U.S., 2020 Earthquakes

An interactive geonarrative with a plain-language summary of the four 2020 Intermountain West (IMW) earthquakes that occurred in Utah, Idaho, Nevada, and California.

Earthquake Tour of Santa Rosa, California

This geonarrative (Esri Story Map) takes you on a virtual tour of 1906 and 1969 earthquake damage in Santa Rosa, shows examples of buildings that have been retrofitted to protect against future earthquake shaking, and highlights locations where faulting from large earthquakes and slow fault slip (creep) is expressed at the ground surface. 

The 2019 Ridgecrest, California, Earthquake Sequence

This USGS geonarrative (Esri Story Map) summarizes the USGS response and findings after the M6.4 on July 4 and M7.1 on July 6, 2019 in Searles Valley, Southern California, and includes links to USGS research publications and data releases.

ShakeMap

ShakeMap is a USGS product in conjunction with regional seismic networks. ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. They are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, preparedness, and disaster planning.

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.

What to Expect in a Big Urban Earthquake - A Geonarrative

How do we get ready for big earthquakes in populated areas? An important first step is to learn what a big earthquake could be like. These pages summarize the main patterns — the earthquake effects that show up again and again. Here, urban is shorthand for “cities, towns, and suburbs”.

Digital database of recently active traces of the Hayward Fault, California

This map shows the location of and evidence for recent movement on active fault traces within the Hayward Fault Zone, California.

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.

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.
