The scary thing is that epicenter is in line from the Sea of Cortez to Palm Springs. and half of that distance in CA is all way below sea level. If the marsh flats and lower elevation flat areas are penetrated in the south near Mexicali, there really isn’t anything preventing a tsunami from the Sea of Cortez from coming all the way up to Indio and Indian Wells and Palm Desert. Its somewhat of an extension of the lower San Andreas and Salton Sea has been a hot spot for seismic swarms and volcanic activity within 3 mi the surface for the last decade or two.
Here in Rancho Mirage I felt 3 large crests of the ground wave 10 seconds after first tremor perceived, and I’m protected in a wash in the mountains adjacent to bedrock.
Greetings from the Top O’ the Cove in La Quinta.....your tsunami theory would instantly take care of a huge chunk of the immigration issue.
