[CEUS-earthquake-hazards] USGS shallow shear wave velocity (Vs30) database available

[Oliver Boyd]

Dear CEUS list subscribers,

On behalf of Alan Yong at the USGS, I would like to inform you that the USGS has released a VS30 database for sites across the United States. VS30, the time-averaged shear-wave velocity (VS) in the upper 30 meters, is a key index adopted by the earthquake engineering community to account for seismic site conditions. The USGS has compiled measured VS30 funded by the USGS and other governmental agencies for 2997 sites in the United States.  The compilation is expected to expand as new and additional information are available. You may find the database and supporting information here: http://earthquake.usgs.gov/research/vs30/

 

If you have questions or know of additional data that should be considered for the database, please contact Alan Yong (yong at usgs.gov).

 

Regards,

Oliver
