M6.4 #earthquake near Ferndale, CA: Seismicity for today (red), the past year (orange) and back to 1982 (green-blue-purple). Views from above/south/east. Today's events may be in upper part of down-going, Gorda plate.
And, since seismicity is only the edges and shadows of complex, 3D space-time tectonic processes, the best is an animated view in 3D!
