Our Earthquake Forecast gives the largest likely earthquake in your lifetime, everywhere on Earth, based on your location. Technically, it is the earthquake magnitude that has a 1% chance per year of occurring within 100 km of your location. We also show active faults in 80 countries, and worldwide earthquakes in the past 30 days, which can be filtered by time period and magnitude.

Our Earthquake Score takes into account all earthquakes near and far, large and small, plus very approximate information about your home’s seismic resilience. It is provided everywhere on Earth. A score of 100 means that over a 30-year period, you are most likely to lose 20% of the value of your home or building to seismic damage.

In the U.S., we estimate your home or building’s most likely financial losses and repair time, and the chance of injury, in the largest likely earthquake that could affect you. This calculation finds the USGS scenario earthquake that produces the strongest shaking at your location, and then accesses data to estimate your home or building’s fragility.

In the U.S., Temblor also lists participating insurance agents, retrofit contractors, quake prep consultants, insurance alternatives, structural engineers, and structural products manufacturers. There is a click-to-call button for all of these providers near you.

What’s new

You can now register without a password via an unlock code sent to your cell phone. You don’t need to enter it again as long as you do not logout. 


We now provide more complete and more valuable seismic risk information for your home or building, with the repair cost in the largest likely earthquake—with and without seismic retrofit, and with and without earthquake insurance at various deductibles. This is something insurance company calculate but do not show to buyers.


We have implemented a more comprehensive algorithm for the Earthquake Score. It now takes into account whether you are in a liquefaction, landslide, or fault zone.

Our new earthquake catalog merges events from a dozen seismic networks around the world, and tags the events as either mainshocks or aftershocks. You can filter the catalog by time period and magnitude, and zoom or pan the map, with a corresponding clickable table.


We now provide push notifications for moderate or larger earthquakes near you.

The app now includes our news articles, which were previously in a separate website. We now are registered to assign DOI numbers, so that the articles are searchable in Google Scholar and their scientific citations are tracked.
