Tremr monitors seismic activity worldwide in real time using the USGS Earthquake Hazards Program feed, refreshed every five minutes. The list below shows earthquakes filtered by your selected magnitude and time range. Click or tap any event to see full details including depth, coordinates, and tsunami status. Use the Menu to adjust the time window, minimum magnitude, and sort order, or enable Near Me to focus on earthquakes within a set distance of your location. For deeper context on what the numbers mean, read the guide below and our articles on magnitude vs intensity, shallow vs deep earthquakes, and how to read a ShakeMap.
Tremr’s live monitor is a fast view of global seismicity from USGS data. It is not a substitute for official alerts from your local emergency agency — and a star on the map is only the start of the story.
Magnitude measures energy at the source. A jump of 1.0 means about 32 times more energy. Large magnitude far away may feel weak; moderate magnitude nearby can still be damaging. Always read magnitude with depth and distance.
Shallow earthquakes (often under ~30 km near cities) couple more energy into buildings. Deep events can be felt widely while causing less local destruction. On any event card, treat depth as seriously as magnitude.
