The Lompoc earthquake of 1927 occurred at 5:49 a.m. Pacific Standard Time (PST), on November 4 with an epicenter off the coast of Lompoc, Santa Barbara County in Southern California. This is one of the largest earthquakes to have occurred offshore, having a moment magnitude between 7.1 and 7.3. The earthquake may have originated along the Hosgri Fault, an entirely offshore structure. Shaking from the earthquake and an unusually large tsunami caused some damage to communities near the earthquake. Due to its location and the area being sparsely populated at the time, there were no human fatalities reported. It is the only California generated tsunami recorded in Hawaii.
