1088 2.0 Earthquake Mount ST. Helens. Northern Ca EQ activity
4 Mar 2026
A 2.0 magnitude earthquake occurred near Mount St. Helens, with some seismic activity recorded in the Pacific Northwest, Alaska, Japan, and the Philippines. While Mount St. Helens experienced a few earthquakes, there is no significant inflation or deflation trend, and the GPS data shows deflation. The Cascadia subduction zone and Southern California are relatively quiet, with only minor earthquake activity.
Earthquake activity is low, with a few small events in the US and a 5.3 magnitude quake in the Mariana Trench. The Kilauea volcano shows deflationary activity, suggesting an eruption in a few days. A slight risk of severe weather is expected across the central US for the next few days, with a wet and potentially stormy weekend.
* Global Earthquake Activity: A 3.5 magnitude earthquake occurred along the Peru-Chile Trench. Increased seismic activity was observed along the Aleutian Trench, Japan, Mariana Trench, and Philippines. * Pacific Northwest Seismic Events: Several earthquakes, including a 2.0 magnitude event, were reported near Mount St. Helens. * Mount St. Helens Seismograph Analysis: Examination of the Mount St. Helens Seismograph Station data revealed a 2.0 magnitude earthquake, with its waveform characteristics suggesting a stronger event than typical microquakes. * Seismic Activity Monitoring: Monitoring earthquake activity, particularly around Mount St. Helens, using seismograph data and GPS stations to track potential volcanic unrest. * Mount St. Helens Status: Observing minor earthquake activity and deflation at Mount St. Helens, indicating no significant volcanic recharging at the moment. * Cascadia Subduction Zone Activity: Reporting a small number of minor earthquakes (magnitude 2) in the southern Cascadia subduction zone, with no major events detected. * Seismic Activity in California: Mostly microquakes along the plate boundary. * Recent Swarms in Nevada: Several swarms in the past few months, including one near Las Vegas, but currently quiet. * Yellowstone National Park Activity: Acidic geyser showing renewed activity, but no significant changes in inflation or uplift. * Yellowstone Activity: Minimal earthquake activity, potential wind events. * Global Seismic Activity: Minor earthquakes, uptick in P chilli trench and middle America trench. * Largest Recent Earthquake: 5.3 magnitude, 118 miles deep in the Mariana Trench. * Volcano Monitoring: Seismograph stations appear quiet, with minor seaf flare activity observed. * Sunspot Analysis: Sunspots are weak and disorganised, with a minor region (4384) showing potential for M flare activity. * Geomagnetic Activity: KP index reached G1 class storm levels due to negative BZ component, but no major aurora activity is expected. * Volcano Monitoring: Monitoring deformation data at Kilawaway volcano, Big Island of Hawaii. * Severe Weather Outlook: Slight risk of tornadoes, wind, and hail for Wednesday and Thursday, with potential for severe weather continuing into the weekend and next week across Texas and Arkansas. * West Coast Weather: Rain expected towards the third week of March, with temperatures in the 70s and 80s. * Earthquake Update: A couple of small earthquakes occurred in Japan.
