Frequently asked questions

How many earthquakes occurred in 2018? ▼
In 2018, the USGS catalog recorded 14,495 earthquakes of magnitude 4.0 or greater worldwide. Of these, 133 reached M6.0 or above.
What was the strongest earthquake in 2018? ▼
The strongest catalogued earthquake in 2018 reached magnitude 8.2, near 2018 Fiji Earthquake. There were 16 M7+ events during the year.
How does 2018 compare to other years? ▼
A typical year sees roughly 13,000–18,000 catalogued M4+ earthquakes worldwide. 2018 recorded 14,495, with an average depth of 101 km. See the year index for the full long-term trend.
What magnitude scale is used? ▼
All magnitudes use the moment magnitude scale (Mw), the USGS standard. The scale is logarithmic, each whole step is roughly 32× more energy released.

About this data

Every figure on this page is computed directly from the USGS Comprehensive Earthquake Catalog (ComCat), the public-domain record maintained by the USGS Earthquake Hazards Program. The worldwide catalog covers magnitude-4.0-and-above events from 2005 onward, the period over which the global seismograph network reliably detects and locates earthquakes everywhere. Magnitudes use the moment-magnitude scale (Mw), the modern standard that supersedes the older Richter scale; because the scale is logarithmic, each whole step up represents roughly thirty-two times more energy released. Depth is measured in kilometres from the surface, and shallow earthquakes generally produce stronger surface shaking than deep ones of the same magnitude. Annual counts reflect what instruments recorded, not every tremor that occurred; the current calendar year is always partial and will keep rising as the USGS adds and revises events, so it should never be compared directly against completed years.
