Worldwide Volcano Current Activity Report

I still try to monitor Marsili and Katla Volcano

EGON, FLORES ISLAND, INDONESIA
PVMBG reported that on 7 April the Alert Level for Egon was raised from 1 to 2 (on a scale of 1-4) due to a marked increase in seismic activity since 28 March. Small steam plumes normally rose 10 m above the crater.

ETNA, SICILY, ITALY
INGV-CT reported that on 8 April a dozen low-frequency events located near the summit of Etna were detected by the seismic network. Concurrently, a dark-colored ash plume rose 1 km from a pit crater located at the E base of the Southeast Crater and drifted NE. Dark emissions from the central crater were also seen a short time later. Ashfall was reported from a few local areas. On 9 April intense gas emissions were noted at the pit crater.

GAUA, VANUATU

Note a green dot in the center of this picture
SO2 mass : 721 tonnes
max SO2 column at 5 km at Gaua Eruprion: 1.55 DU equal with 0.0155 mm layer of SO2 at 0 C at 1 atmosphere

On 7 April, the Vanuatu Geohazards Observatory reported that recent field observations of Gaua confirmed significant changes in activity. Gas plumes were detected daily by satellite images. During the end of March through the beginning of April, ash plumes rose daily to altitudes of 2.1-3 km (7,000-10,000 ft) a.s.l. Explosions were heard in nearby villages. Starting on 3 April villagers living in the N and S parts of the island reported ashfall and saw bombs ejected from Gaua. Based on Vanuatu Geohazards Observatory information, the Wellington VAAC reported that during 8-12 April ash plumes rose to an altitude of 3 km (10,000 ft) a.s.l. Ash plumes were seen on satellite imagery on 11 and 12 April drifting S and SE. The Vanuatu Volcano Alert Level (VVAL) remained at 2 (on a scale of 0-4).


MIYAKE JIMA, IZU ISLANDS, JAPAN
Based on information from JMA, the Tokyo VAAC reported an eruption from Miyake-jima on 11 April. Details of possible resulting plumes were unknown.

REVENTADOR, ECUADOR

The Washington VAAC reported that on 8 April an ash plume seen by pilots rose to altitudes of 4.6-6.7 km (15,000-22,000 ft) a.s.l. and drifted West. The VAAC also noted that seismicity was elevated.
