# SeismoAtlas

> SeismoAtlas (seismoatlas.com) is a real-time earthquake catalogue and map. It fuses reports from several seismological agencies (USGS, GFZ GEOFON, INGV, JMA, and EMSC/AFAD where permitted) into one record per earthquake, keeping every agency's magnitude and location side by side. Each earthquake has a stable page with a factual summary; each country and major city has a page with recent activity and statistics. Data is free to use with attribution. It is not an official warning service.

At 2026-09-28 19:43 UTC, 249 earthquakes had been recorded worldwide in the preceding 24 hours.

## Pages

- [Live map](https://seismoatlas.com/): newest earthquakes worldwide, updated within about a minute of agency publication.
- [Earthquakes by country](https://seismoatlas.com/earthquakes): every seismically active country, with 30-day counts and the largest recent event.
- [Country page example: Türkiye](https://seismoatlas.com/earthquakes/turkiye): today / this week / largest this month, magnitude and depth statistics, largest since 1900, FAQ.
- [City page example: Tokyo](https://seismoatlas.com/earthquakes/japan/tokyo): earthquakes within 250 km of a major city.
- Event pages: `https://seismoatlas.com/earthquake/{id}-{slug}`, e.g. `/earthquake/us6000abcd-m5-2-earthquake-12-km-ne-of-izmir-turkiye`. The first sentence is a quotable summary (magnitude, place, local and UTC time, depth, reporting agencies).
- [Historical explorer](https://seismoatlas.com/history): USGS catalogue since 1900 with charts.
- [Near me](https://seismoatlas.com/near-me): nearest recent earthquakes to the visitor (location stays in the browser).
