The earthquake swarm beneath the volcano continues.
A couple of weak volcanic tremor events and low-frequency quake periods have been registered since 28 August. Given observations indicating signs of elevated unrest, a decision has been made to raise the current Aviation Color Code from "Green" to "Yellow".
Quakes were located at deep levels firstly, at about 25 km depth, but have become progressively shallower up to approx. 7-to-5 and even 0 km depth since 28 August.
The elevated seismic activity may indicate that increased fluid movements of gas, water and possibly magma shift under the surface.

Trident volcano (Alaska) - Smithsonian / USGS Weekly Volcanic Activity Report for 28 September-4 October 2022 (New Activity / Unrest)

AVO raised the Aviation Color Code for Trident to Yellow (the second lowest level on a four-color scale) and the Volcano Alert Level to Advisory (the second lowest level on a four-level scale) on 29 September due to an ongoing seismic swarm. The swarm began on 24 August and within about four days the seismic network began detecting episodes of weak seismic tremor and low frequency earthquakes. The events were initially located at depths around 25 km, but then they progressively shallowed to around 5 km by 28 August. ... Read all
