The post-2008 seismicity has occurred both in areas that were seismically active before 2008 (for example, the Mississippi embayment) and in regions with no pre-2008 historical or instrumental seismicity (for example, FWB).

Research shows North Texas earthquakes occurring on ‘dead’ faults

Seismic record captured by the seismometer installed in the ICTJA-CSIC during the Bruce Springsteen concert at Camp Nou on May 14, 2016. The upper panel shows the seismogram, while the lower panel shows the spectrogram where it is possible to see the distribution of the energy between the different frequencies. You can distinguish the different songs of the concert and highlight those performed during the encores towards the end of the concert
