Do you mean worldwide or in a specific country/region?
If you mean worldwide (typical averages):
- Roughly a few hundred thousand earthquakes are detected by instruments every year. Most of these are tiny and occur far from people.
- Typical annual averages (approximate):
- ~10–20 of magnitude 8.0 or larger
- ~50–200 of magnitude 7.0–7.9
- ~1,000–2,000 of magnitude 6.0–6.9
- ~10,000–20,000 of magnitude 5.0–5.9
- Many more (hundreds of thousands to millions) of smaller quakes below magnitude 5
Counts vary year to year. For exact numbers for a given year or region, the USGS (or International Seismological Centre) earthquake catalogs provide up-to-date counts and searchable lists — tell me if you want guidance on how to look those up or want current-year totals for a particular area.
