how often do earthquakes happen

Earthquakes happen all the time somewhere on Earth, but most are too small to feel. Global monitoring agencies locate about 12,000 to 14,000 earthquakes a year, and the number drops sharply as magnitude increases.

Quick Scoop

• Tiny earthquakes happen hundreds to thousands of times a day worldwide, depending on how small you count them.

• Around magnitude 7 and above, there are roughly 15 to 20 a year globally, or about one every couple of weeks.

• Very large earthquakes are much rarer than small ones, and the yearly count can vary a bit without meaning activity is increasing overall.

What that means

A useful rule is that for each step up in magnitude, earthquakes become about 10 times less frequent. So while small quakes are constantly happening, the big damaging ones are uncommon.

Simple takeaway

If you’re asking “how often do earthquakes happen?” the short answer is: every day, everywhere in the world —but most are minor and only a small fraction are strong enough to be widely noticed.
