ALAN SCOTT The ongoing earthquake swarm near Takawangha volcano continued over the past week, although seismic data from the local network experienced an outage over the past day which was resolved this morning. Infrasound measurements from the @alaska_avo confirm that it was indeed coincident with the volcanic pressure wave. Since then, the swarm has declined and currently small earthquakes are occurring at the rate of about 5 to 10 events per hour. It might not erupt. The movement doesnt mean an eruption will happen soon or even at all from Southeast Alaskas most prominent volcano, but its significant enough that the observatory has raised the volcanos threat level.
