The 1965 Puget Sound earthquake occurred at 08:28 AM PDT (15:28 UTC) on April 29 within the Puget Sound region of Washington state. It had a magnitude of 6.7 on the moment magnitude scale and a maximum perceived intensity of VIII (Severe) on the Mercalli intensity scale. It caused the deaths of seven people and about $12.5–28 million in damage.
The 1965 Rat Islands earthquake was one of the largest on record. Despite this only minor damage was caused due to the remote location. A tsunami was triggered. Property damage costs were $10,000 (1965 rate). Several large aftershocks followed. Only magnitude 6.5+ events will be listed to prevent cluttering. 4 [16] United States, Rat Islands ...
Damaging earthquakes are well known in the Pacific Northwest, including several larger than magnitude 7, most notably the M9 1700 Cascadia earthquake and the M7.0–7.3 earthquake in about 900AD on the Seattle Fault. The M6.5 1965 Puget Sound earthquake shook the Seattle, Washington, area, causing substantial damage and seven deaths. This event ...
