Live Earthquake Map
Earthquakes around the world as USGS and EMSC report them, merged into one live map with magnitude, depth, time and the agencies behind each report.
New-earthquake alerts
For new events in World at M2.5+ (your current filters). Alerts only work while this page is open in a tab; nothing runs in the background and nothing is sent to us.
This is not an earthquake early-warning system: reports arrive minutes after shaking.
Felt an earthquake?
Report it to the official agencies. This page does not collect reports.
- Magnitudes and locations are revised; the first automatic values often change.
- In an emergency, follow your local authorities.

Frequently asked questions
Where does the earthquake data come from?
From two public sources that your browser contacts directly. The US Geological Survey publishes real-time GeoJSON feeds of its ComCat catalogue, which combines the USGS National Earthquake Information Center with regional networks; USGS data are in the public domain. The European-Mediterranean Seismological Centre (EMSC) collects reports from agencies worldwide, such as AFAD in Türkiye, INGV in Italy, BMKG in Indonesia and CSN in Chile, and shares them under the CC BY 4.0 licence. Nothing about you is sent to ZumaTools.
What is the difference between magnitude and intensity?
Magnitude describes the size of the earthquake at its source, so one event has one magnitude, although agencies may report different values or types. Each whole step on the magnitude scale means about ten times larger ground motion on a seismogram and about 32 times more energy released. Intensity describes how strongly the shaking was felt at a particular place, on the Modified Mercalli scale from I to XII, so it changes with distance, depth and local ground. USGS “Did You Feel It?” reports measure intensity.
Why do USGS and EMSC show different magnitudes or locations for the same earthquake?
Each agency uses its own stations, Earth models and magnitude types, for example local magnitude (ML), body-wave magnitude (mb) or moment magnitude (Mw), and the first values are computed automatically and revised later. National networks usually locate their own earthquakes best. The map treats two reports as one event when they are no more than 60 seconds, 100 km and 0.5 magnitude units apart, shows both solutions side by side, and puts a local agency first when USGS has only its global solution.
How often does the map update?
USGS regenerates its summary feeds every minute, and this page checks them every minute while it is visible. EMSC sends new and updated events through a live websocket as soon as they are published. An earthquake still has to be detected, located and released by an agency first, which usually takes a few minutes for automatic solutions and can take longer for small or remote events.
What does earthquake depth mean?
Depth is how far below the surface the rupture began, the hypocentre. Earthquakes shallower than 70 km are called shallow, 70 to 300 km intermediate and 300 to 700 km deep. For the same magnitude, shallow earthquakes usually cause stronger shaking at the surface. Depth is the least certain part of a location; when the data cannot pin it down, agencies often fix it at a default such as 10 km.
Can this page warn me before an earthquake?
No. It is not an early-warning system: events appear only after an agency has detected and published them, typically minutes after the shaking. The alert options only work while this page is open in a browser tab. For official warnings and emergency advice, follow your local authorities and national seismological agency.
About this tool
This live earthquake map brings the two largest public real-time earthquake sources onto one screen. The USGS feeds cover the whole world with particular detail in the United States, while EMSC relays solutions from dozens of national agencies, which makes it strong in Europe, the Mediterranean and many other regions. The page downloads both in your browser, merges duplicate reports of the same earthquake and shows every event once, with the agencies that reported it.
Circles are sized so that each magnitude step makes them about 1.55 times wider, which keeps a magnitude 7 clearly larger than a magnitude 5 without hiding everything around it; the energy released grows by about 32 times per magnitude step, following the Gutenberg–Richter relation log E = 1.5 M + 4.8. Earthquakes from the past hour pulse, small events are grouped into clusters at low zoom, and the plate boundaries from Peter Bird’s 2003 global model show why earthquakes line up along the Pacific Ring of Fire, the Alpine–Himalayan belt and the mid-ocean ridges.
The statistics strip counts earthquakes by magnitude band for the range and filters you choose, names the largest one and plots how many occurred per hour. The time-lapse replays the period so that aftershock sequences and swarms become visible. Event details include USGS felt reports, the PAGER alert level for estimated impact and the USGS tsunami flag, which is only set for large events in oceanic regions and does not by itself mean a tsunami exists.
Treat the numbers as the agencies do: first magnitudes and locations are automatic and often change during the first hour, and small events may be missing or deleted later. For felt reports use USGS “Did You Feel It?” or your national agency.
