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.

On 3 February AVO stated that the seismic swarm that began at Takawangha on 23 January continued but at a decreased rate and intensity. The rate of earthquakes peaked at 190 events on 24 January, and since then had steadily declined; 2-8 events per day were recorded from late January to 3 February. Most of the events were located 7-8 km ESE, at shallow depths. The Aviation Color Code remained at Yellow and the Volcano Alert Level remained at Advisory.

AVO reported that an energetic earthquake swarm on Tanaga Island began on 23 January, with earthquakes located 6-7 km ESE of Takawangha volcano, and was possibly due to brittle failure in the surrounding rock caused by magma movement. AVO raised the Aviation Color Code to Yellow and Alert Level to Advisory.
