Complete with chalkboard-like scientific diagrams, the vehicle once belonged to Richard Feynman, the late Nobel Prize-winning Caltech physicist.

Southern California, in all of 2024, had 15 seismic sequences that included at least one quake that had a magnitude of 4.0 or stronger, said Lucy Jones, a seismologist and Caltech research associate.
