#shakemovie simulation - Venezuela event using M7.2 & M7.5 double CMT solutions from USGS. this uses the updated M7.2 CMT (half-duration 17.5s) and the M7.5 CMT (half-duration 0.5s - weird for an event of such magnitude). body waves might have triggered the Kuji M6.9 event #specfem3D_globe

#specfem3d peak-ground motion (PGV) shakemap of the time-reversal simulation of the Birch glacier collapse. it should highlight the event site - but sometimes things are not so simple.

Last Friday, two strong Mw6.2 earthquakes struck near Panama and Alaska - just ~3 minutes apart - followed by a smaller Mw5.7 quake. As if Panama and Alaska decided to sync up.. here’s a #shakeMovie visualization - watch as they light up the Earth with some nice fringes #specfem3dGLOBE

#SPECFEM codes hit 30,000+ citations! awkward moment. when your simulation software has a bigger social circle than you do and your code is more popular than you’ll ever be. 🙂 well done Dimitri. specfem.org
