List of earthquakes in 1969
This is a list of earthquakes in 1969. 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 (USGS) ShakeMap data. Activity generally was slightly below average with 14 events reaching magnitude 7 or greater. The largest event was off the coast of Portugal in February and measured 7.8. Other parts experiencing large events were Indonesia and Russia. The Americas had no events above magnitude 7 which is an uncommon occurrence. Of the 4,000 deaths from earthquakes two events dominated. Southeastern China had an earthquake of magnitude 5.7 in July which contributed 3,000 of the total. Indonesia had the bulk of the rest of the death toll.
