Roundup of Global Volcanic Activity

Cleveland (Aleutian Islands, Alaska): A small explosion at the volcano was recorded on 16 April by both infrasound (air pressure) and seismic data. No ash plume could be observed due to cloud cover. AVO raised the alert status of Cleveland to Orange. Since the small eruption on Saturday morning, no other signs of eruptive activity have been detected.

Popocatépetl (Central Mexico): A large summit eruption (a paroxysm) occurred during yesterday night at the volcano. The eruption began around 02:15 local time on 18 April, when ash emissions and individual explosions in the summit crater increased, followed by a strong eruptive phase with continuous lava fountains that lasted over 2 hours. During its peak around 3 am local time, a rain of incandescent material fell over the upper part of the volcano, to up to 1.6 km distance, and an ash plume rose several kilometres and drifted SE. Moderate ash fall occurred in areas such as Puebla city, whose airport was of course shut down.
