Note: The inclusion criteria for adding events are based on WikiProject Earthquakes' notability guideline that was developed for stand-alone articles. The principles described also apply to lists. In summary, only damaging, injurious, or deadly events should be recorded.
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.
This earthquake was a 6.8 moment magnitude that caused $2 billion damage while the Northridge earthquake was a 6.7 moment magnitude, but caused more than $20 billion worth of damage as the hypocenter of the Northridge earthquake was much shallower and closer to the surface of the earth. [17] [18]
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings — later followed by seismotomography imaging technique, [1] observations using space satellites from outer space, [2] artificial intelligence (AI)-based earthquake warning systems [3] — they rely mainly ...
WA state has the second-highest risk of large earthquakes in the U.S., according to the Washington Department of Natural Resources.

Of particular concern are signals of massive earthquakes in the region’s geologic history. Many researchers have chased clues of the last “big one”: an 8.7-magnitude earthquake in 1700.
Earlier this month, Washington joined California and Oregon in using the U.S. Geological Survey's ShakeAlert system for earthquake early warning. The program, which has been in the works since ...
