An earthquake. Even your post linked details faultlines. In California. San Andreas, to be exact. With the earthquake zone over any faults. Earthquakes often shake a few times. Two Earthquakes shown, they were quite clustered, and localised earthquakes, but both can cause huge fatality. 6.4 and 7.1. Earthquakes have aftershocks, 26,000 listed, they also quake consecutively. Etc. I missed the scale of it. Miles. On the map.
Naval base, speculation it was weapon testing there, why would it? It could be suicidal. Need a bigger Earthquake, next time.
