Preserving Historic Earthquake Records and Photos of the Instruments that Recorded Them
Release Date: FEBRUARY 4, 2019 A project to scan a small selection of the film chips of historical earthquake recordings to digital files was started in 1996. In addition to archiving historic data from the early years, the USGS has also worked to archive photos and descriptions of early seismometers.
Collection of 3D Geometries of Global Subduction Zones
Release Date: NOVEMBER 12, 2018 A new picture of the geometry of subducting slabs around the world, the locations of the world’s largest earthquakes.
Debris-Flow Forecasts Before Wildfires
Release Date: OCTOBER 15, 2018 USGS scientists have been pursuing a way to assess debris-flow hazards before a fire occurs.
New Methods for Dating and Sequencing Ancient Earthquakes Along the Wasatch Fault Zone
Release Date: OCTOBER 12, 2018 Complex geologic sites, like those between the fault segments along the Wasatch fault zone in Utah, make the dating and ordering past earthquakes a difficult task. Two new methods were used to make this task easier and to get better results.
A New Map of Rodgers Creek Fault in Sonoma County, California
Release Date: JULY 16, 2018 A new more detailed and higher resolution map of the Rodgers Creek Fault in Sonoma County, California, has been produced using aerial photography and hillshade imagery derived from LiDAR data.
Near Realtime Maps of Possible Earthquake-Triggered Landslides
Release Date: JUNE 25, 2018 USGS scientists have been developing a system to quickly identify areas where landslides may have been triggered by a significant earthquake.

Earthquake shaking — Finding the "hot spots" Earthquake shaking — Finding the "hot spots"
A new Southern California Earthquake Center study has quantified how local geologic conditions affect the shaking experienced in an earthquake. The important geologic factors at a site are softness of the rock or soil near the surface and thickness of the sediments above hard bedrock. Even when these 'site effects' are taken into account, however, each earthquake exhibits unique...
