Where does the earthquake data come from?

All earthquake data is sourced directly from the United States Geological Survey (USGS) Earthquake Hazards Program, which monitors seismic activity worldwide in real-time using a global network of seismometers.

How often is the earthquake data updated?

The USGS updates their earthquake feeds every minute. With auto-refresh enabled, this monitor fetches new data every 5 minutes, or you can manually refresh at any time.

What does the earthquake magnitude mean?

Earthquake magnitude measures the energy released during an earthquake on a logarithmic scale. Each whole number increase represents roughly 32 times more energy. Magnitudes below 2.5 are rarely felt, 2.5-5.4 are often felt but cause minor damage, 5.5-6.0 cause slight damage, 6.1-6.9 can be destructive, 7.0-7.9 are major earthquakes, and 8.0+ are great earthquakes that can cause severe destruction.

What does earthquake depth indicate?

Earthquake depth indicates how far below the Earth's surface the earthquake originated. Shallow earthquakes (0-70 km) often cause more surface damage, intermediate depth (70-300 km) earthquakes are felt over larger areas, and deep earthquakes (300+ km) typically cause less surface damage but can be felt very far from the epicenter.

Is this earthquake monitor completely free to use?

Yes, this earthquake monitor is 100% free to use with no subscriptions, sign-ups, or hidden fees. It's part of FreeWWW's mission to provide genuinely free tools and utilities to everyone.

About This Monitor

This free earthquake monitor displays real-time seismic data from the USGS (United States Geological Survey). Track earthquakes worldwide, filter by magnitude and depth, and explore detailed information about each event.

How to Use

Select a time period to view recent earthquakes. Use the magnitude slider to filter events. Click on map markers or list items to see detailed information. Toggle auto-refresh to keep data current.

Magnitude Scale

Earthquake magnitude measures energy release on a logarithmic scale. Each whole number increase represents 32x more energy. Events below 2.5 are rarely felt, while 7.0+ can cause major destruction across large areas.

Depth Categories

Shallow earthquakes (0-70 km) cause more surface damage. Intermediate depth (70-300 km) events are felt over larger areas. Deep earthquakes (300+ km) typically cause less surface damage but travel far.
