DONATE TODAY – help TXESP serve our global community of Science


DYK that #seismologists have also served their Country? Help #TXESP continue **contributing to science**, through our service, and go beyond being only users of science!

Historically and currently, seismologists help monitor sub-surface #nuclear #weapons testing. #Seismographs detect the ground motion which occurs after a nuclear #detonation. The ground shaking produces seismic waves which can be monitored remotely by seismologists. This seismogram detected a nuclear explosion in #NorthKorea on 09/09/2016 at 00:30hrs UTC ; it was recorded on an EQ-1 seismograph in Spring, TX, USA.
