The city is on the North American tectonic plate and is partially divided by the San Andreas Fault line. It is also situated near the Pacific Ring of Fire, where approximately 75% of the world's seismic activity occurs.One of the most catastrophic earthquakes to hit the city occurred on April 18, 1906. Dubbed the "Great 1906 San Francisco Earthquake," the quake ruptured the San Andreas fault with a magnitude of 7.9. According to First Post, people who experienced the natural calamity described the sound similar to "the roar of 10,000 lions."Houses after the 1906 earthquake (Image via Getty)The quake killed over 3000 people, destroyed 30,000 buildings, and 80% of the city fell into rubble or burned down in the fires. According to CBS News, the city commemorated 119 years since the disaster in April 2025, with residents gathering at Lotta's Fountain at Market and Kearney streets. Mayor Daniel Lurie delivered a speech to mark the event, saying:"This event, this commemoration, just gives me hope and inspiration. We should all have that optimism that they had after this catastrophe, because they brought it back. And we're going to bring San Francisco back again. We know that another earthquake can strike at any moment. And I know our first responders are preparing every single day. We are ready and we continue to prepare ourselves for whatever comes next," he said.The earthquake in San Francisco occurred weeks after an 8.8 magnitude earthquake struck Russia in July 2025. According to ABC News, this earthquake resulted in tsunami waves being recorded in Hawaii and other coastal areas in the Pacific US, including California.
