I know, volcanic eruptions arent that rare but this one started a few hours ago and there are live pictures from various local tv stations
It would be very interesting to know. In fact it is the great underlying question, without undermining the great concern and uncertainty of these moments.fresh_42 said:The Cumbre has a predetermined breaking fault. It would be interesting to know whether it is affected by the current outbreak or not.
https://en.wikipedia.org/wiki/Cumbre_ViejaLOS LLANOS DE ARIDANE, Spain (AP) — A volcano on Spain’s Atlantic Ocean island of La Palma erupted Sunday after a weeklong buildup of seismic activity, prompting authorities to evacuate thousands as lava flows destroyed isolated houses and threatened to reach the coast. New eruptions continued into the night.
The Canary Islands Volcanology Institute reported the initial eruption shortly after 3 p.m. near the southern end of the island, which saw its last eruption in 1971. Huge red plumes topped with black-and-white smoke shot out along the Cumbre Vieja volcanic ridge, which scientists had been closely watching following the accumulation of molten lava below the surface and days of small earthquakes.
There were articles alluding to this last week, before the volcano but probably in response to a series of tremors happening since the saturday before the eruption for example thisAstronuc said:https://news.yahoo.com/spanish-island-braces-possible-earthquakes-102021556.html

La Palma is the island of concern with respect to a massive chunk falling into the Atlantic Ocean setting off a tsunami that could/would impact the Caribbean Islands and Atlantic Coast of US (North America).

Testing whether a given tsunami model is correct is complicated by the rarity of giant collapses. The term "megatsunami" has been defined by media and has no precise definition, although it is commonly taken to refer to tsunamis over 100 metres (330 ft) high.
I will definitely be concerned if Yellowstone or Napoli reports a major eruption. And the Cumbre is interesting because his (existing) fault widens every time encapsulated rainwater is vaporized. So if the eruption took place near that fault, it meant an additional countdown to the major event.anorlunda said:So what?
I don't think people should neurotically obsess over catastrophes portrayed by Hollywood, but certainly, if some major event is likely to happen, which could mean 1/100 to 1/100,000 years, or 10-6 years-1, one could or should be prepared, as much as one should be prepared for a Cat 5 hurricane or a 25 to 30 foot (8-10 m) tidal surge. It's a bit like having a tornado shelter in a region that is prone to tornadoes, or parts of California (or west coast) subject to earthquakes, or Seattle-Tacoma area prepared for an eruption of Mt. Rainier, or massive earthquake associated with the Juan de Fuca plate.anorlunda said:Likely or not, statements like that attract lots of journalistic attention, and make Hollywood disaster movies. It's a certainty that a tsunami will hit the USA East Coast someday, and that an asteroid will collide with Earth, and that the Sun will expand to a red giant. So what?
Data from Spain's National Geographic Institute shows how a series of small tremors began to take place on 11 September under a mountain range known as Cumbre Vieja, leading scientists to believe there could be magma pushing under the surface of the Earth.
This seismic activity gradually moved to the surface and, in the two days before the eruption, tremors were felt only 100m underground.
The Canary Islands Volcano Institute has suggested the eruption could last between 24 and 84 days.
I heared the announcement yesterday, and a statement that the eruption has destroyed 100s of buildings and cost more than $1 billion in economic (including property) losses. It will take time to understand the magnitude of the impact. I also wonder how long before the next eruption.mcastillo356 said:"... , the authorities declared yesterday ended the eruption of the Cumbre Vieja volcano"
Seem to be good news. Still waiting for more information. It had been 85 devastating days.
The live volcanic eruption in Canary Islands, Spain is caused by the movement of tectonic plates. The Canary Islands are located on a geological hotspot, where magma from the Earth's mantle rises to the surface, creating volcanic activity.
The live volcanic eruption in Canary Islands, Spain can be dangerous for those living in close proximity to the volcano. It can also cause air pollution and disrupt air travel. However, authorities are closely monitoring the situation and taking necessary precautions to ensure the safety of residents and visitors.
It is difficult to predict the exact duration of the live volcanic eruption in Canary Islands, Spain. It could last for a few days, weeks, or even months. It will depend on the intensity of the eruption and the behavior of the volcano.
Yes, there are several warning signs that can indicate an impending volcanic eruption. These include increased seismic activity, changes in gas emissions, and changes in the shape of the volcano. Scientists closely monitor these signs to predict and prepare for a volcanic eruption.
The live volcanic eruption in Canary Islands, Spain can have various impacts, including damage to infrastructure, displacement of residents, and disruption of air travel. It can also have long-term effects on the environment, such as changes in soil fertility and water quality. However, the extent of these impacts will depend on the severity and duration of the eruption.
