Tanaga and Takawangha Volcanoes Tanaga Island, Alaska - March 2023

[Astronuc]

I was listening to a video last night about the possibility of an imminent eruption of the Tanaga and Takawangha volcanoes on Tanaga Island, Alaska. There has been a noticeable increase in seismic activity consistent with the rise of a magma chamber.

At 2215 on 7 March AVO raised the Aviation Color Code for Tanaga to Yellow and the Volcano Alert Level to Advisory due to increased seismicity. Earlier that afternoon, starting at about 1330, seismicity began to increase and by around 2045 earthquakes were occurring at a rate of 2-3 per minute. The events were located at shallow depths and the largest events were M2-3.

AVO reported that the earthquake swarm at Takawangha that began in November 2022 was ongoing with 120 earthquakes located during 25 February-3 March. The number of events per day was highest on 28 February and 1 March, with over 50 earthquakes located on each of those days. Three earthquakes had magnitudes greater than 3, occurred at shallow depths of less than 6 km, and were located about 6 km E of the volcano. During 3-7 March small daily earthquakes with magnitudes less than M2 occurred in the vicinity of the volcano. The Aviation Color Code remained at Yellow (the second lowest level on a four-color scale) and the Volcano Alert Level remained at Advisory (the second lowest level on a four-level scale).

Tanaga (elevation: 5,924 feet; 1,806 m) last erupted in 1914, producing https://volcano.oregonstate.edu/sites/volcano.oregonstate.edu/files/vwdocs/glossary.html#lava%20flow Tanaga has had three known eruptions since 1763. Takawangha (elevation: 4,795 feet; 1,462 m) is a https://volcano.oregonstate.edu/sites/volcano.oregonstate.edu/files/vwdocs/glossary.html#holocene and has not erupted in historic time. Takawangha has an ice-filled https://volcano.oregonstate.edu/sites/volcano.oregonstate.edu/files/vwdocs/glossary.html#caldera with minor tephra cones on the flanks, on the rim and within the caldera.

There is a concern for an explosive (phreatic) eruption if magma rapidly reacts with groundwater in caldera of Takawangha.

Nice info in those videos too!

It seems the Earth is going crazy with volcanoes, earthquakes, tsunamis, and the scare of a pole shift.
