These data include seismic waves generated by the collapse of Warren Hall, located at California State University – East Bay (CSUEB) in Hayward. The implosion was purposefully triggered to demolish the unsafe building in August 2013.
All data were recorded in the IRIS-PASSCAL field format, with individual files having the format, “IxxxxRAW.TRD”, where xxxx is the 4-digit seismograph (DAS) number. For conversion to other formats, contact the IRIS-PASSCAL data center or contact the authors of this report. The trd files consist of continuously recorded data for each seismograph, and each file extends from the turn-on time until that seismograph was turned off following pickup from the recording sites.
