Roundup of Global Volcanic Activity

Etna (Sicily, Italy): Last night, a marked peak of volcanic tremor occurred as sign of internal unrest at the volcano, but (unlike during many previous occasions) did not result in a paroxysm and was not associated with any particular change in surface activity. urrently, this consists of mild strombolian explosions inside the Voragine summit crater. During the past hours, volcanic tremor has bee rising strongly. In the past, this has often been a sign of an impending paroxysm (violent summit eruptive phase). Whether this is the case now is too early to say. So far, no significant activity is visible from the New SE crater (NSEC), although a hot spot is present on thermal webcam images.

Semeru (East Java, Indonesia): The lava dome inside the summit crater continues to grow slowly. Andi climbed the volcano a few days ago and observed continuous degassing, sometimes followed by minor explosions.
