A year of strong earthquakes
Each spike is a magnitude 5.5+ earthquake of the last twelve months (USGS ComCat); its height follows the magnitude, its colour the depth. Rings mark the strongest. Earthquakes outline the plate boundaries.
- < 70 km (shallow)
- 70–300 km (intermediate)
- > 300 km (deep)
Positions and magnitudes from the USGS catalogue; heights exaggerated. Base map: local NASA Blue Marble.

The USGS ComCat (ANSS) catalogue is read through the FDSN web service, one request per calendar year since 1900 for magnitudes ≥ 4.5; the last two years are re-read on each update because solutions are revised. Magnitudes are those published (mb, Ms, Mw, ml…) and are not converted; depth is the hypocentre depth in km.
Yearly counts are computed on the server from imported events of type “earthquake” (explosions and other types are kept but excluded from counts). Historical earthquakes and their tolls come from the NCEI/WDS significant earthquake database, dated to the year when the day is unknown.
