@USATODAY "... That monster shoots up the most terrible jets of fire; it is a marvellous wonder to see, and a marvel even to hear about when men are present."

Pindar (15-28) tells the myth: buried under the mountain lies the giant Typhon, who tried to overthrow Zeus.

ACTIVITY REPORT (#THREADE

37.748°N, 14.999°E;
summit elev. 3320 m

All times are local (unless otherwise noted)
INGV reported that Strombolian activity from all four of Etna’s summit craters, the Southeast Crater (SEC), Northeast Crater (NEC), Bocca Nuova (BN), and Voragine (VOR), was visible during 8-14 February.
The frequency and intensity of explosions at SEC were variable; almost continuous strong explosions originated from two vents in the E part of the top of the cone. Tephra accumulated near the top of the cone and rolled several tens of meters down the flanks.

Five assets have been mobilized by the Philippine Coast Guard to fetch the people on the volcano island and bring them to safety. About 200 individuals were targeted for pre-emptive evacuation from Sitio Tabla and Sitio San Isidro, it said.
@phivolcs recorded 98 tremor episodes having durations of 5 to 12 minutes in the last 24 hours.

Activity Report

"University of the West Indies Seismic Research Centre (UWI-SRC) and National Emergency Management Organisation (NEMO) reported
that the lava dome in Soufrière St. Vincent’s main crater that first formed on 27 December continued to grow during 6-12 January. Observations were made during a field visit on 5 January, during a helicopter overflight on 6 January, and based on 9 January drone video.
During that time the dome grew and expanded to the W, produced small, hot rockfalls, had a blocky appearance, and continued to emit gasses and steam. Gas-and-steam plumes were also visible from Belmont Observatory.

Most actual Update report to the #Merapi #Volcano #Java

"BPPTKG reported that during 25-31 December rock avalanches traveled as far as 1.5 km down Merapi’s NW flank in the Senowo drainage.
A comparison of photos taken on 24 and 30 December showed minor morphological changes in the summit area. Seismic activity was more intense than the previous week.
Electronic Distance Measurement (EDM) data continued to measure a distance shortening between points in the NW at a rate of 14 cm per day. Incandescence from the crater was visible at night on 31 December, possibly signifying the emergence of lava.

ACTIVITY REPORT

A new effusive eruption had built a lava dome in the summit crater of Soufrière St. Vincent when observed on 29 December by personnel from the National Emergency Management Organisation (NEMO), Image
St. Vincent and the Grenadines, and the Alert Level was raised to Orange (the second highest level on a four-color scale). The observers noted that the small black-colored dome had grown on the WSW edge of the 1979 lava dome.
The University of the West Indies Seismic Research Centre (UWI-SRC) stated in a press briefing that seismicity at the volcano began to increase in early November and changes in the water lake and fumarolic area were noted on 16 December.

#StVincentAndTheGrenadines #Kingstown #Volcano #SoufriereStVincent #Warning

As volcanoes begin to spray ash after lying dormant for decades, residents of St Vincent and the Grenadines have been ordered to leave their homes. ImageImageImageImage
Authorities have issued a warning for the region, impacting over 100,000 people, as the current eruption is assessed by scientists. Officials warned on Tuesday of heavy gas emissions, the creation of a new volcanic dome and improvements to the La Soufriere volcano's crater lake. Image
The warning level was increased to an orange today, with indications that the volcano could erupt within a day and urge people to evacuate. The decision to raise the level of alarm comes as it began to spew ash and a new volcanic dome was created.

#USA #Hawaii #Kilauea #Volcano #Eruption

The Kilauea in Hawaii is one of the most active volcanoes in the world and a popular tourist destination. But people should stay away from the volcano because it haunts ash and lava.
The eruption began yesterday evening inside the volcanic basin on the Big Island, said the US earthquake monitoring station USGS. Clouds of red steam rose into the night sky, as seen in images of Hawaii Volcanoes National Park.
The USGS warned that a lot of volcanic ash could enter the atmosphere. Aircraft are said to fly around the area around Kilauea. The US weather service warned that the wind could carry the ashes to villages in the southwest of the island.

NEW ACITIVTY REPORT

According to PVMBG continuous tremor at Lewotolo began to be recorded at 19:43 on 26 November, and a series of volcanic earthquakes began at 19:47.
A new eruption started at 05:57 on 27 November, producing dense blackish gray ash plumes that rose 500 m above the summit and drifted W. Incandescence at the summit was visible, and the emissions turned white around 06:30.
Seismicity slightly decreased after the eruption, though continuous tremor persisted for a period of time. Dense white plumes rose as high as 400 m and nighttime incandescence was noted during 27-28 November.
