DOI: 10.1002/2017gl073504
Abstract: We revisit the significance of the increased number of great earthquakes since December 2004. Analysis of the global seismic moment release during 1918–2014 inferred from the International Seismological Centre (ISC) catalog rejects a null hypothesis… read more here.

DOI: 10.1016/j.jvolgeores.2020.107034
Abstract: Abstract Previous studies have found discrepancies concerning the seismic radiation between planar and curved faults; moment tensor (MT) interpretations, seismic moment estimation and waveforms change dramatically when the rupture is not planar. Therefore, assuming a… read more here.
