PPT-Remote hydroacoustic and infrasonic detection and characterization of eruptive activity

Kaelynn M Rose 1 Robin S Matoza 1 1 Department of Earth Science and Earth Research Institute University of California Santa Barbara CA USA Poster No P23708 P23708 ABSTRACT A climactic eruption phase on December 22 2018 triggered the collapse of the southwest flank and summit of Anak Krakatau stratovolcano generating a tsunami which struck the coastlines of Sumatra and Java We employ a selection of remote moored hydroacoustic and infrasonic stations of the International Monitoring System IMS to investigate eruptive activity preceding during and after the climactic eruption phase We observe 7 months of coeruptive intermittent infrasound at IS06 and powerful infrasound from the climactic eruption on IS06 and IS52 The climactic eruption phase was not detected hydroacoustically but we observe a 12day swarm of hydroacoustic signals beginning 24 days before the flank collapse event that we attribute to sustained submarine eruptive activity at Anak Krakatau . The eruption commenced with a small phreatomagmatic event followed by subplinian events on 26 and 27 January Lava emerged as a dome in the summit crater on 27 January and 64257lled the crater until the beginning of February During the subplinian eve Francisco Delgado.
