The largest earthquake in the past 24 hours was a magnitude 6.6 event near southern East Pacific Rise, which occurred at 17:43 UTC at a depth of 10.0 km.
How many earthquakes happen per day worldwide?
The USGS typically detects 150 to 300 earthquakes of magnitude 1.0 or greater each day worldwide. Earthquakes of magnitude 4.0+ average around 50 per day; M5.0+ average around 4-5 per day; M6.0+ average around 1-2 per week.
Why are there so many earthquakes today?
Earthquakes occur constantly along tectonic plate boundaries. Apparent clusters are usually normal background seismicity, aftershock sequences from a recent larger event, or earthquake swarms in specific regions. Today's count of 171 is normal activity.

About This Page
Earthquakes Today is maintained by Earthquake Tracker, an independent seismic activity reporting service. We compile real-time earthquake data from the U.S. Geological Survey (USGS) Earthquake Hazards Program, which detects and catalogs earthquakes worldwide using a global network of seismometers.
Data is updated every 5 minutes. Counts include all earthquakes of magnitude 1.0 or greater detected in the past 24 hours. Smaller earthquakes may not be detected in remote regions or deep ocean locations. Significance classifications use USGS standards: M5.0+ events are typically reportable, M4.0+ may be felt locally, and M3.0+ are often reported by residents.
