Global Volcanic Activity – New Activity for the week of 12 June – 18 June 2019

Colima | Mexico : Centro Universitario de Estudios e Investigaciones de Vulcanologia – Universidad de Colima reported that intermittent steam-and-gas emissions mainly from the NE side of the crater and small explosions continued to be recorded during 8-14 June. Weather conditions often prevented visual observations of the crater.

Pavlof | United States : On 12 June AVO reported that elevated levels of seismicity at Pavlof, recorded since mid-May, had declined to background levels. The Aviation colour Code was lowered to Green and the Volcano Alert Level was lowered to Normal. The report noted that vapor plumes were occasionally visible in webcam views and elevated surface temperatures in the summit crater were sometimes identified in satellite images; both are common occurrences at Pavlof.

Piton de la Fournaise | Reunion Island (France) : The eruption at Piton de la Fournaise that began at 0635 on 11 June continued through 12 June from fissures on the SSE flank of Dolomieu Crater. The front of the lava flow had reached around 1,200-1,300 m elevation by 0620. OVPF stated that the eruption ended at 1200 on 13 June.

Sangeang Api | Indonesia : The Darwin VAAC reported that on 17 June multiple discrete emissions with increasing ash content over a period of about an hour rose from Sangeang Api to altitudes of 1.2-2.1 (4,000-7,000 ft) a.s.l. and drifted W and WNW, based on satellite images and weather models. A thermal anomaly was also visible. The Alert Level remained at 2 (on a scale of 1-4).
