Based on the successful borehole broadband seismometer STS-5A used by USArray/Transportable Array in the Alaska deployment at more than 70% of the stations, Kinemetrics launches another Streckeisen borehole seismometer, the very broadband Model STS-5A-360, with the response extended from 120 seconds to 360 seconds. The STS-5A-360 was selected by USGS as secondary seismometer for the Global Seismographic Network (GSN)
