NEW CRATER! Huge Lava Flow on Iceland Volcano – Lava moving towards visitors

Large explosion reported at La Soufrière Volcano in St Vincent

The Trinidad-based Seismic Research Centre (SRC) of the University of the West Indies (UWI) today reported a “large explosion” at the La Soufriere volcano.

In a brief update posted on its website, the SRC said that its team monitoring the volcano, which erupted last Friday, “has observed a large explosion at approximately 4:15 am (local time) and pyroclastic density currents(flows) have been observed on the flanks of the volcano”.

The SRC said that it is continuing to monitor the situation and will update later.

Volcanologist Professor Richard Robertson yesterday warned that the ongoing eruption of La Soufriere volcano is in keeping with the events surrounding the 1902 eruption which claimed 1,600 lives at a time when early warning systems and evacuation capabilities were not as advanced.

Speaking on the state-owned NBC Radio, Professor Robertson, the lead scientist monitoring the volcano, said that while most people know of the 1979 eruption, what is currently happening at La Soufriere is more akin to more a century ago.

“The activity pattern we have currently is more similar to a 1902 type of eruption of that kind of scale, rather than a 1979 scale. The people who lived through 1979 know the kind of eruption we have had.

“What does that mean? It means, unfortunately, that it is likely going to cause more damage and destruction to St Vincent but it also means that there will always be a safe place in the south of the country, which might have a lot of ash every now and then, but you can still sustain life and limb and it would not — which is what we all worry about — get so big that it destroys the whole country. That currently doesn’t seem to be the case.”

Third lava stream cracks in Icelandic volcano

A third eruption fissure cracked open on April 6, in between the two already existing ones.

Drone footage filmed on Friday (April 9) showed the second fissure surrounded by a blanket of snow.

The volcano on the Reykjanes Peninsula, some 30 kilometres southwest of the capital Reykjavik, started to erupt on March 19 and has become a tourist attraction, drawing thousands of visitors.

Volcanologists have no idea how long the eruption will continue, saying it could stop soon or continue for years, possibly even decades.

Eruption With Lava Flow At Kilauea Volcano In Hawai’i

A new eruption started at Kilauea volcano in the evening of 20 Dec in Hawaii (local time). The volcano observatory reported:

“Shortly after approximately 9:30 p.m. HST, the USGS Hawaiian Volcano Observatory (HVO) detected glow within Halemaʻumaʻu crater at the summit of Kīlauea Volcano. An eruption has commenced within Kīlauea’s summit caldera. The situation is rapidly evolving and HVO will issue another statement when more information is available.”

During the past weeks, earthquakes had been more frequent under the caldera and the upper rift zone. They likely reflected magma intrusions at shallow level.

Shortly after the new eruption, observed less than two hours ago, a magnitude 4.3 quake struck the southern flank of the volcano, about 10 miles west of Kalapana. This quake might be related as a response to the new eruption, probably causing a small southwards movement of the southern flank of Kilauea, acting as adjustment for the additional space needed of the magma intrusion in the summit area.

Strong Strombolian-to-Vulcanian Explosive Activity Continues at Fuego Volcano in Guatemala

Vulcanic explosion generated incandescent material that slid down along the slopes of the volcano (image: @newsandnature01/twitter)

The activity of the volcano continues at moderately high levels during the past week.

INSIVUMEH reported that a moderate-to-strong strombolian-to-vulcanian-type explosions erupted at regular intervals of 6 to 8 per hour. Plume of ash rose to an altitude of 4,700 ft (15,420 m) and extending about 10 km to the N-NE of the volcano.

A strong vulcanic explosion occurred on 28 November at 02:11 local time showering the summit cone with glowing lava bombs ejected to an approximate height of 300 m above the crater.

Moderate Explosion at Villarrica Volcano, Chile

Occasional explosions of the volcano continue.

On 5 December at 18:44 local time the volcano observatory SERNAGEOMIN recorded a moderate explosion associated with long-period (LP) earthquake.

An ash plume rose 524 ft (160 m) above the summit and drifted south-southeast and caused fresh ash deposits on the snow cover visible in the images.

The small lava pond continues to be active in the inner active vent. There is a 500 m exclusion zone around the main crater in place.

New eruption at Piton de la Fournaise Volcano in (La Réunion, France), Indian Ocean

New eruption of Piton de la Fournaise volcano this morning (image: OVPF/IPGP)

A new eruption started at the volcano this morning. At around 2.28 am local time, the seismic network of the observatory detected a seismic crisis, typical sign of magma pushing its way towards the surface. Other instruments detected rapid local ground deformation, another tell-tale sign of an impending eruption.

At around 4.40 am, volcanic tremor was recorded by the instruments, reflecting now a continuous flow of magma towards the surface. The first lava probably came out shortly after, at around 4.50-4.55 am. 3 fissures opened at altitude between 2190 and 2300 m on the southwestern flank of the summit cone and started to erupt small lava fountains, about 15 m tall, from a chain of vents.

The eruption has been producing multiple lava flows that started to descend slowly on the flanks. By the time of first visual observations made by scientists on an aerial survey a few hours later, the most advanced lava flow front had descended to 2120 m altitude. Given this rather low rate of advance and low height of lava fountains, the discharge rate of this eruption seems rather low compared to most previous eruptions of Piton de la Fournaise.

Today’s eruption marks the third of the volcano in 2020, after eruptions in February and April this year. It followed a period of frequent seismic unrest, last detected during the morning of 4 Dec. These preceding periods likely reflect intrusions and the recharging of shallow magma reservoirs, events that often build up to eruptions like the current one. Piton de la Fournaise is one of the world’s most active volcanoes and typically erupts several times each year.

Lava Flow Increases at Pacaya Volcano in Guatemala

The effusive-explosive eruption of the volcano continues.

The lava flow on the southwestern eruptive fissure has increased in length, currently about 525 m long.

Weak-to-moderate strombolian-type explosions continue from the Mackenney summit crater with ejecta thrown at an approximate height of 20 and 50 meters.

The seismic instruments recorded internal tremor associated with explosions and lava flow and magma rising within the volcano edifice.

Hundreds flee as Mount Semeru spews lava and ash in Java, Indonesia

Volcano Alert

Hundreds of Indonesians have fled their villages after a rumbling volcano spewed hot ash thousands of metres into the air and belched lava down its crater.

Mount Semeru on Java island spouted the towering column on Tuesday, prompting a call for around 500 people to temporarily evacuate their homes.

Footage from the scene showed dead livestock covered by pyroclastic flows — a fast-moving mixture of hot gas and volcanic material — as steaming debris flowed into a nearby river.

Local disaster agency chief Agus Triono warned on Wednesday that residents could still be at risk as heavy rains threatened to trigger more volcanic flows from the still-spewing crater.

The eruption came days after Mount Ili Lewotolok roared back to life on the far eastern end of the archipelago nation.

Around 6,000 residents fled to shelters there after the crater ejected a thick tower of debris four kilometres (2.5 miles) into the sky on Sunday, triggering a flight warning and the closure of a local airport.

There were no reports of injuries or deaths.

Indonesia is home to about 130 active volcanoes due to its position on the “Ring of Fire”, a belt of tectonic plate boundaries circling the Pacific Ocean where frequent seismic activity occurs.

In late 2018, a volcano in the strait between Java and Sumatra islands erupted, causing an underwater landslide that unleashed a tsunami which killed more than 400 people.
