In the Fault Zone

On April 18, 1906, a massive earthquake centered just west of San Francisco ruptured the earth from Humboldt to San Juan Bautista. While the more dramatic traces of this 7.8 temblor may be hard to find one hundred years later, the tectonic forces that moved the earth that day are still relentlessly shaping our young and active landscape, carrying us towards another cataclysm in the near future.

On The Move

All of the familiar landforms we see here in the Bay Area—ridges, cliffs, lakes, and even San Francisco Bay itself—are products of the same titanic encounters between tectonic plates that produce our frequent quakes. Through a geologist’s trained eye, we learn to interpret the signs these forces have left on the land around us.
