Science for Everyone. It is thought that more damage was done by the resulting fire after the  1906 San Francisco earthquake  than by the earthquake itself.

This amounts to around 20,000 earthquakes annually. Estimated total annual earthquake energy release (magnitude 8 earthquake = 1 = 1,000 magnitude 6 earthquakes) in red; 7-year average in grey. Learn about a variety of earthquake topics.

Annual earthquake-related fatalities per million population, worldwide, 1900-2010 It is estimated that there are  500,000 detectable earthquakes  in the world each year. From this number, they estimate that there are 500,000 detectable earthquakes in the world each year. Some earthquakes which are large enough to be detected may also go unnoticed because they occur in isolated areas where there are … Many earthquakes are undetected by the USGS; in fact, the organization estimates that around several million earthquakes occur around the globe annually. 100,000 felt, 100s cause damage (0.01%) Small amount of those that felt and cause damage (magnitude small/less energy that doesn't cause damage) Some places that no one lives/no roads or buildings. There are probably several million earthquakes in the world every year, but the majority of these are too weak to be detected with current instruments. 1 million detectable earthquakes happen every year. USGS resources and links to outside educational resources. 100,000 of those can be felt, and 100 of them cause damage. Earth is an active place and earthquakes are always happening somewhere. The United States Geological Survey estimates that there are around 50 earthquakes per day in the world that can be located. Science briefs about new earthquake research written for non-scientists.

100,000 of these will be felt by humans and 100 of them will be large enough to cause damage. According to the United States Geological Survey, more than 3 million earthquakes happen each year. That's one earthquake every 11 seconds! Fun and educational resources including Science Fair ideas and earthquake science you can understand. In fact, the National Earthquake Information Center locates about 12,000-14,000 earthquakes each year! Earthquake Topics. The  U.S. Geological Survey  (USGS) estimates that 500,000 detectable earthquakes occur in the world each year.
