Fuego and Merapi activity - Brief news from La Palma.

A new eruptive stage has been in place at Fuego since March 5.

From 6 p.m. on March 6, the audible parameters of the Fuego Volcano Observatory, OVFGO, seismic and acoustic recordings increased, noticing this increase in rumble with moderate to loud characteristics and sounds similar to those of a locomotive at constant train and a moderate aircraft turbine.

Strombolian activity is observed in the crater of the volcano, which feeds two lava flows of 400 and 200 meters in length respectively advancing in the barrancas Ceniza and Santa Teresa.

An incandescent source, from a height of between 100 and 200 meters above the crater, generates moderate to strong avalanches towards the ravines of the Fuego volcano, mainly the barrancas Ceniza, Trinidad and Santa Teresa.

Pyroclastic flows, composed of gas, ash and blocks of rock at high temperature, were observed descending into the barranca Ceniza between 12:03 p.m. and 2:31 p.m. The flows traveled about 7 km.

Ash falls are reported in Panimaché, Morelia, Santa Sofia, Yucales, El Porvenir and Sangre de Cristo, with a noticeable deterioration in air quality.

In the evening, the OFGO records an increase in seismic parameters greater than that recorded in the last 24 hours, resulting from the large quantities of pyroclastic flows, mainly in the barranCa Ceniza, with a possibility in the barranca Las Lajas.

An evacuation process in the village of Morelia, Yepocapa, Chimaltenango has been launched; Approximately 220 people will be transferred by bus from the Ingenio Pantaleón to the Santa Lucia Cotzumalguapa Fairgrounds, Escuintla. Conred advocates self-evacuation

This eruption is of the Strombolian type and can generate new lava flows towards more ravines, as well as produce violent ash-laden explosions and generate pyroclastic flows towards one of the Fuego volcano ravines.

It is not recommended to stay near or inside the canyons of the volcano.

An avalanche pyroclastic flow was recorded at Merapi on March 7, 2022 at 8:39 p.m. WIB on a seismogram with an amplitude of 34 mm and a duration of 158 seconds. The glide distance is 2,000 m to the southwest.

In addition, the seismicity of March 7 is characterized by: 
- 115 collapse earthquakes, with an amplitude of 3 to 25 mm and a duration of 9 to 207 seconds.
- 1 blast/emission earthquake, with an amplitude of 6 mm and an earthquake duration of 17 seconds.
- 6 hybrid/multiphase earthquakes, with an amplitude of 1-13 mm, S-P 0.4-0.9 seconds and an earthquake duration of 4.8-7.4 seconds.
- 1 distant tectonic earthquake with an amplitude of 4 mm, for 80 seconds.

The level of activity remains unchanged at 3 / siaga, as does the extent of the risk areas.

Some news from La Palma and Cumbre Vieja:

The National Geographic Institute issues the certificate of the new official surface of the municipality of Tazacorte on the island of La Palma after the eruption of the Cumbre Vieja volcano, based on a first perimeter of the bands provided by the public company of Canary Islands Grafcan
The new official area of ​​the commune is 12.04 km²; The town has grown by 47 ha.

IGEO researcher and UCM physics professor A. Negredo published a document during GeocienciasEnElCole week: " Cumbre Vieja, what is a volcano like you doing in such a place? "

Recent ESA studies, in which Spanish researchers participate, confirm the presence of a large amount of hot material under the Canary Islands, down to depths of 400 km. This hot zone of the mantle is represented on the image below in orange.
