How Waves, Earthquakes, and Other Forces Shape the Southern California Coast with Keith H. Meldahl, Ph.D.

Wednesday, April 20

6:30 p.m. Social—7:00 p.m. Program

Keith-MeldahlWhat is it about Southern California and earthquakes? Why are we so prone to experience these earth-shaking events? Are there forces at work right now that will impact the incidence and severity of future tremors?

The answers to those questions all revolve around the simple fact that Southern California is sandwiched be-tween two tectonic plates that grind relentlessly past one another. Over the last sev-eral million years, movements of these plates have dramatically reshuffled the Earth’s crust to create rugged landscapes and seascapes riven with active faults. Movement along the faults triggers earthquakes and tsunamis, pushes up mountains and islands, and lifts sections of coastline high above the sea. Over geologic time, beaches come and go, coastal bluffs retreat, and the sea rises and falls. Nothing about Southern California’s coast is stable.

surf-sand-and-stoneOur April program speaker, Keith Meldahl, not only understands all of this, but is also uniquely qualified to make it understandable for the rest of us. He is Pro-fessor of Geology and Oceanography at MiraCosta Col-lege. He earned his BA in geology from the University of Chicago and his MS and PhD in geology from the University of Arizona. He is the author of several books, including Surf, Sand, and Stone, which tells the scientific story of the Southern California coast.

Come join us as we take a virtual geologic excursion from San Diego to Santa Barba-ra. Our expert guide will reveal evidence about how the coast’s features came to be, and how they are continually evolving.
