Caribbean volcanoes, dormant for decades, rumble to life – Videos

Tens of thousands of people on high alert – Scientists study activity not seen in years

The most recent warning was issued for La Soufriere volcano in St. Vincent and the Grenadines, a chain of islands home to more than 100,000 people. Officials reported tremors, strong gas emissions, formation of a new volcanic dome and changes to its crater lake.

Historically, La Soufriere erupts at Grand Solar Minimums, says Diamond at Oppenheimer Ranch. It erupted at the Centennial Minimum, the Dalton Minimum and the Maunder Minimum.

The Caribbean Disaster Emergency Management Agency said that scientists observed an “effusive eruption within the crater, with visible gas and steam” on Tuesday.

A new lava dome is seen.

 

The government warned those living near the volcano to prepare to evacuate if needed, declaring an orange alert that means eruptions could occur with less than 24 hours’ notice.

La Soufriere, located near the northern tip of the main island of St Vincent, last erupted in 1979. Earlier, an eruption in 1902 killed some 1,600 people. Before that, La Soufriere’s last major eruption was in 1812.

The 1902 killer eruption occurred shortly before Martinique’s Mt Pelee erupted and destroyed the town of Saint-Pierre, killing more than 30,000 people.

Mt Pelee is also now active once again. In early December, officials in the French Caribbean territory issued a yellow alert due to seismic activity under the mountain. It was the first alert of its kind issued since the volcano last erupted in 1932, said Fabrice Fontaine, with Martinique’s Volcanological and Seismological Observatory.

The activity at Mt. Pelée and La Soufrière is not related., said volcanologist Erik Klemetti, at Denison University in Ohio.

“It’s not like one volcano starts erupting that others will,” said Klemetti. “It falls into the category of coincidence.”

Just a coincidence? I think not.

Especially since other ‘sleeping’ volcanoes are awakening in Indonesia, Sicily, Iceland and La Palma.

  1. Does a quiet Sun have anything to do with it? (I doubt it, but just askin’.)

    It is interesting that so many in that chain of islands are suddenly waking up. Sounds like part of a cycle to me, but I’ll go check Volcano Live and see if there’s anything there.

    • From what I have read from Robert and others, seismic activity increases with GSMs so more earthquakes and volcanoes.

    • Yes, the Sun has just finished a significant Angular Momentum affected orbit around the Solar System, Barry Centre during SC24 the first active cycle of the Modern Grand Solar Minimum. Similar active cycle(s) can be seen during each GSM and many Gleissberg Periods, which directly influence the Earth’s Tectonic plates via GRAVITY in the way both the Sun and Moon causes the tidal flow of the oceans. Icelandic volcanic research has already document historic eruptions during and lagging GSM periods. Dalton had two major events with Tambora the last, the 585 LALIA GSM had three massive T7 eruptions and created the Vandal Minimum 585 to 800AD.
      Many other volcanic eruptions have taken place during all of the named GSM throughout the LIA period

    • The good news is that this may stop Bill Gates from polluting the atmosphere to “stop global warming.”

  2. you found extra, good film too;-))
    amused me they said the lava isnt as “runny” as hawaiis, i think its kaboom /splat factor would still be pretty awesome
    Hawaiia lava still flowing I gather
    whats going to happen if the hollow fills in I wonder?

  3. … activity at Mt. Pelée and La Soufrière is not related…

    The Soufrière Hills are an active, complex stratovolcano with many lava domes forming its summit on the Caribbean island of Montserrat. Many volcanoes in the Caribbean are named Soufrière (French: “sulfur outlet”). These include La Soufrière or Soufrière Saint Vincent on the island of Saint Vincent, and La Grande Soufrière on Guadeloupe. After a long period of dormancy, the Soufrière Hills volcano became active in 1995 and has continued to erupt ever since. Its eruptions have rendered more than half of Montserrat uninhabitable, destroying the capital city, Plymouth, and causing widespread evacuations: about two thirds of the population have left the island.[3]
    It is andesitic in nature, and the current pattern of activity includes periods of lava dome growth, punctuated by brief episodes of dome collapse which result in pyroclastic flows, ash venting, and explosive eruption.

  4. La Soufriere Volcano update – 3rd January 2021

    The big concern on St Vincent is a Pelean style eruption, which produce avalanches of hot ash that race down the side of the mountain and flatten everything in their path. The Soufriere Hills volcano on Monserrat produced Pelean eruptions when it awoke back in the 1990’s. Everyone in the area knows what Monserrat looks like today. As you might have guessed, Pelean eruptions are named after Mount Pelee volcano on Martinique. It erupted in 1902 and killed everyone in Saint-Pierre at the time except for 1 lucky survivor [who was in a below ground level jail cell]. Caribbean volcanoes are very dangerous for this reason.
