Recent seismic activity along Alaska’s fault lines has pushed seismologists and geologists to agree upon a larger seismic event occurring in the foreseeable future. Since seismic activity in these areas is normal, don't panic. After a spike in volcanic activity, seismic activity, and ice quakes in the region over the last month, the idea of a tsunami has been explored more now than ever before.
The region is known for its seismicity, and the reach of a tsunami from this area would be rather extensive. Alaska’s fault lines branch down southward, along the west coast of Canada, and into the west coast of the United States. Geologists are considering the likelihood of a tsunami from Alaska reaching Washington, Oregon, and California.
Historically, tsunamis triggered by Alaskan seismic activity have stemmed from volcanic activity. Today, Alaska’s Great Sitkin Volcano has been under ‘Orange Watch,’ which is an indication that an eruption is underway. Furthermore, a handful of other Alaskan volcanoes are also under the watchful eye of local seismologists.
Alaska’s most recent seismic activity can be found on Alaska Earthquake Center. The following earthquakes have been documented by USGS and AEC, two of the most credible and globally-recognized seismic activity monitoring systems used in the region. UTC is an abbreviation for Coordinated Universal Time.
Magnitude 3.2 Earthquake Struck 35 km West of Ambler, Alaska: On 5 June 2023 at 10:25 AM UTC, a magnitude 3.2 earthquake struck Amber, Alaska, at a surface level depth.
Magnitude 2.7 Earthquake Struck 61 km East of Chignik, Alaska: On 4 June 2023 at 3:35 PM UTC, a magnitude 2.7 earthquake struck Chignik, Alaska, at a depth of 28.1 km.
Magnitude 2.5 Earthquake Struck 89 km South of Lowell Point, Alaska: On 5 June 2023 at 3:50 AM UTC, a magnitude 2.5 earthquake struck Lowell Point, Alaska, at a depth of 4.6 km.
