Takawangha volcano (Andreanof Islands, USA) - Smithsonian / USGS Weekly Volcanic Activity Report for 16 November-22 November 2022 (New Activity / Unrest)

Wed, 23 Nov 2022, 15:00
15:00 PM | BY: VN
On 18 November AVO raised the Aviation Color Code for Takawangha 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) based on increased seismicity. The number of small earthquakes detected near the volcano had increased during the previous few days and intensified during 17-18 November. The earthquakes were located at depths of 3-6 km below sea level with the largest magnitudes between 2 and 3.
The seismicity possibly indicated magma movement at depth. The intensity of the seismicity was variable during 19-22 November.
