Temblor gives individuals the tools to understand their personal earthquake risk. Temblor provides free individualized earthquake risk information to the public. It’s the same basic info that we license to the insurance industry — the difference being volume of locations and depth of the analysis. This distinguishes us from other risk model vendors (e.g., RMS, AIR, CoreLogic), which are closed to the public. “Impressive Earthquake App. Way more here than the other 'earthquake apps.'” — J.D. Check your risk Under the “Your Risk” tab, enter your home address (or a city, state or geographic landmark) or find your location and instantly see the earthquake magnitude that location is likely to experience in your lifetime. Use the map layers to explore various hazards including shaking, liquefaction susceptibility, wildfire hazard and more (depending on location). Check your risk everywhere on Earth. Pan and zoom to view all recent earthquakes anywhere on the planet. Temblor merges earthquake catalogs from the major seismic agencies around the world into one real-time display of global earthquakes in the past 24 hours, 2 days, 7 days or 30 days. View faults throughout the world or in your backyard. Quake Alerts Temblor will send you a notification when an earthquake strikes near your location. This is NOT an earthquake early warning and is not intended to inform you of impending shaking. Various agencies around the world distribute early earthquake warnings to earthquake-prone regions. We encourage you to seek out your local agency to receive such alerts. Temblor Earthquake News “Articles” brings you to Temblor Earthquake News, a news platform dedicated to earthquake reporting. Temblor’s mission is to provide the public with accurate, accessible, and understandable information about earthquakes. Read breaking news about major earthquakes, post-quake analyses and the latest developments in earthquake science in easy-to-understand language. Following major or particularly notable quakes, Temblor rapidly publishes accurate post-event analyses to inform the public and support institutional and commercial responses. Temblor is an approved Google News source and has been cited in major news outlets.
