Piton Fournaise: Eruption intensifies

by

The eruption on the Piton de la Fournaise has intensified. On 5th and 7th of March new fissures opened, one of which is still active. There are 2 lava fountains that feed lava flows. The Lava output is about 30 cubic meters per second. The end of the lava flow is at 1000 m altitude. The distance to the coastal road is 5 km. The tremor rose and 49 volcanotectonic earthquakes were registered.

The eruption started on 20. February, just one day after a short-lived eruption.

Bezymianny (Russia) – Report for 27 February-5 March 2019

by

KVERT reported that a thermal anomaly over Bezymianny was identified in satellite images during 28 February-1 March. Strong gas-and-steam emissions continued to be visible. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Karymsky (Russia) – Report for 27 February-5 March 2019

by

KVERT reported that ash plumes from Karymsky were identified in satellite images during 22 and 24-26 February rising as high as 3.5 km (11,500 ft) a.s.l. and drifting 216 km E. A thermal anomaly was visible during 24-25 and 27-28 February. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Piton de la Fournaise (France) – Report for 27 February-5 March 2019

by

OVPF reported that the fissure that opened 19 February at a site located at 1,800 m elevation at the foot of Piton Madoré, E of Piton de la Fournaise?s Dolomieu Crater, continued during 27 February-5 March. RSAM measurements showed fluctuating intensities though an overall upwards trend. Based on satellite images, the main flow front progressed slowly during 22-28 February, advancing only 300 m to 1,200 m elevation. A new lava flow emerged from an area near the cone and traveled NE; the more southern branches did not advance during 28 February-1 March. Scientists conducted fieldwork on 5 March and noted that the cone had grown to 100 m wide at the base, 25 m tall, and had a vent opening 50 m wide. High-temperature gas emissions rose from the vent, and Strombolian activity ejected material. White steam rose from the base of the cone, likely from the presence of lava tubes. The northernmost lava flow remained active.
