Earthquake statistics

Number of quakes per year

Note:
The apparent increase in the number of quakes is not because global seismic activity has increased, but because the number of seismic networks around the world and their sensitivity to detect smaller quakes has been constantly increasing.
This is most evident if one looks at the number of smaller earthquakes (below magnitude 5). For larger quakes (magnitude 5 or more), the effect disappears after around the 1990s. Since then, the global coverage of earthquake of larger quakes has been nearly complete.

Average number of earthquakes

Based on data from the past 54 years and our earthquake archive back to 1900, there are about 375 quakes on average per year near Mount St. Helens volcano:

Mag. 5 or higher: 0.28 quakes per year (or 1 quake every 3.6 years)
Mag. 4 or higher: 6 quakes per year
Mag. 3 or higher: 22.4 quakes per year
Mag. 2 or higher: 28.6 quakes per year
Mag. 1 or higher: 76 quakes per year (or 6.3 quakes per month)

Mount St. Helens volcano (Washington, USA): elevated seismic activity poses no threats so far

Digital elevation model of Mount St. Helens volcano and earthquake density during 1987-2004. Areas with a lot of earthquakes are in blue, while areas with fewer earthquakes are shown in oranges and browns. The earthquakes associated with the current episode are shown in orange (image: CVO)

The Cascades Volcano Observatory (CVO, USGS) reported that seismic activity at the volcano has been elevated over the past three months. ... Read all

St. Helens volcano (Washington) - Smithsonian / USGS Weekly Volcanic Activity Report for 10 May-16 May 2023 (Continuing Activity)

USGS reported that at 2045 on 14 May a debris flow in Mount St. Helens'South Coldwater Creek destroyed a Highway SR 504 bridge, cutting off access and power to Johnston Ridge Observatory. While the loss of power interrupted a major telemetry hub, other stations remined operational and continued to provide data; the debris flow was recorded in seismic data from nearby stations. ...
