The magnitude 6.3 earthquake of June 29, 1925, the first destructive earthquake in California since the 1906 San Francisco quake, destroyed much of downtown Santa Barbara and killed 13 people. The earthquake caused infrastructure to collapse including the Sheffield Dam. The low death toll is attributed to the early hour (6:44 a.m., before most people were out on the streets, vulnerable to falling masonry). While this quake, like the one in 1812, was centered in the Santa Barbara Channel, it caused no tsunami. It came at an opportune time for rebuilding, since a movement for architectural reform and unification around a Spanish Colonial style was already underway. Under the leadership of Pearl Chase, many of the city's famous buildings rose as part of the rebuilding process, including the Santa Barbara County Courthouse, sometimes praised as the "most beautiful public building in the United States." There is also the unfortunate incident that happened in 1907, which included a horrific train accident that took the lives of 32 people.
