Earthquakes occur very frequently around the world. Approximately 12,000 to 20,000 earthquakes are located globally each year, which translates to about 35 to 55 earthquakes per day. Among these, around 100,000 earthquakes annually can be felt by people, while the total number including smaller, undetectable ones can reach several million. Larger earthquakes, such as those with magnitude 7 or higher, tend to occur less frequently, averaging about 15 to 18 major events each year, including one great earthquake (magnitude 8.0 or more) annually. Most earthquakes are concentrated in tectonically active regions like the Pacific Ring of Fire. In summary:

• About 12,000 to 20,000 earthquakes detected worldwide annually
• Several million earthquakes including very small ones occur yearly
• Around 15-18 major earthquakes (magnitude 7+) per year
• One great earthquake (magnitude 8+) per year on average

This frequency is relatively stable over time, with minor statistical fluctuations. Earthquakes can occur at any time, anywhere in the world, but are most common along tectonic plate boundaries.
