If the activity will persist in the increasing trend, this would be a potential tell-tale clue for an impending eruption. The largest earthquake over the past 24 hours was measured to be M 3.9 under the Tanaga volcano so far.
The seismic activity is also elevated at Tanaga volcano, which is about 8 km (5 miles) west of Takawangha on Tanaga Island. If an eruption were to occur, it is uncertain at this stage if it would come either from Tanaga or Takawangha.
To conclude, the AVO observatory raised the Volcanic Alert Level to Orange.
