Description: On January 24, 2017, citing an energetic earthquake swarm, AVO raised the Aviation Color Code and Volcano Alert Level at Takawangha from UNASSIGNED to YELLOW/ADVISORY. The earthquake swarm began January 23. The earthquakes located 6-7 km ESE of Takawangha Voclano. This activity could have been due to brittle failure in the surrounding rock caused by magma movement. No eruptive activity was detected in satellite imagery or other data.
Following a significant decline in the energetic earthquake swarm, with seismicity returning to near background levels, AVO lowered the Aviation Color Code to GREEN and Alert Level to NORMAL for Takawangha volcano on February 8, 2017.
