Takawangha reported activity




Event Name : Takawangha unrest 2023

Start:November 18, 2022 Observed

Seismicity with no confirmed eruption: BibCard
Eruption Type:Not an eruption.

Description: On November 18, 2022, AVO raised the Aviation Color Code and Volcano Alert Level at Takawangha to YELLOW/ADIVSORY, citing "The number of small earthquakes detected near Takawangha volcano has increased over the past few days and has intensified over the past 24 hours. The earthquakes, the largest with magnitudes between 2 and 3, have preliminary depths of about 2 to 4 miles (3 to 6 km) below sea level. This activity may be due to the movement of magma beneath the volcano." This seismicity marks a departure from background activity."

On March 9, 2023, AVO raised Takawangha to ORANGE/wATCH, stating "Over the past 48 hours, earthquake activity near Takawangha volcano has been elevated and continues. This sustained activity indicates an increased potential for eruption at the volcano. Therefore AVO is raising the Aviation Color Code to ORANGE and the Volcano Alert Level to WATCH. Seismic activity is also elevated at Tanaga Volcano, which is about 8 km (5 mi) west of Takawangha on Tanaga Island. If an eruption were to occur, it is uncertain at this stage if it would come from Takawangha or Tanaga."
