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

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.
