Mt. Tongariro Swarm July 11th to 19th 2012

Small volcanic earthquakes have been recorded beneath Mount Tongariro. The sequence started on July 11 UTC, but soon declined, restarting on July 17 and increasing in number on July 19 and 20. These indicate unrest at Tongariro and give reason to change the Volcanic Alert Level to Level 1 and the Aviation Colour Code to Yellow.
