On-Again, Off-Again Lake Cahuilla Likely Enhanced Earthquakes in Southern California

by Nathaniel Scharping 3 July 20235 July 2023

The disappearance of the ephemeral lake has made earthquakes along the San Andreas Fault even more unpredictable.

This snapshot of a new global mantle convection model depicts Earth 180 million years ago, with broad mantle upwellings (in copper) equal to or greater than 1 kelvin meter per year, reconstructed continental blocks (gray polygons), and kimberlite eruptions (magenta columns).
