List of earthquakes in 1973
This is a list of earthquakes in 1973. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Maximum intensities are indicated on the Mercalli intensity scale and are sourced from United States Geological Survey ShakeMap data. Both the number of large events and the death toll were substantially lower in 1973. There were 9 magnitude 7.0+ events. The largest of these was in Japan measuring 7.7. Russia and New Hebrides were active during the year with each country having 2 magnitude 7.0+ events. Nearly 3,000 deaths were reported with China being worst affected.
