Since 10:27 am local time on February 10, 2020, a seismic crisis has been recorded on the instruments of the Volcanological Observatory of Piton de la Fournaise. This seismic crisis is accompanied by rapid deformation, This indicates that the magma is leaving the magmatic reservoir and is propagating towards the surface. A rash is likely soon in the next few minutes or hours.

The volcano erupted around 11 a.m. on Monday morning, February 9, 2020, as confirmed by the Piton de la Fournaise Volcanological Observatory. the site of the eruption is located on the eastern flank of the volcano.

"The eruption is visible from the National Road at the level of the Burned. The eruptive mouth is at 2000 meters above sea level," according to Bertrand Sinama, a local observer / via Imazpress.

Given the presence of hot and incandescent gases, and the possibility of short-term lava emissions, the Prefect decided to implement alert phase 2-2 "eruption in progress in the enclosure" of the specific ORSEC volcano system this Monday, February 10, 2020 from noon.

Public access to the Fouqué enclosure from the Pas de Bellecombe trail or any other trail, as well as the landing of aircraft in the volcano area, are prohibited until further notice.

More information to come.

 

Update 11h GMT
The first photos and videos show a flow emanating from several fissures, which quickly divides into several arms, and which has already traveled a good distance on a steep slope.

Activity in the main crater of Taal in the past 24 hours has been characterized by low emission of plumes loaded with steam rising 20 to 50 m high before drifting to the southwest. Sulfur dioxide (SO2) emissions were measured at an average of 116 tonnes / day on February 8, 2020.

The Taal seismic network recorded seventy-seven (77) volcanic earthquakes, of which eleven (11) harmonic tremors lasting from one (1) to four (4) minutes. These earthquakes signify magmatic activity under the Taal building which could lead to eruptive activity at the main crater.

Alert level 3 is maintained on the Taal volcano. DOST-PHIVOLCS reminds the public that sudden and even weak phreatomagmatic explosions driven by steam, volcanic earthquakes, falling ash and deadly volcanic gas expulsions can still occur and threaten areas of the island of the volcano Taal and the shores of the lakes nearby. DOST-PHIVOLCS recommends that entry to the island of the Taal volcano as well as to the areas on Lake Taal and the communities to the west of the island within a radius of seven (7) km from the main crater must be strictly prohibited.
