Several swarms or seismic series have been recorded on the Cumbre Vieja volcano in La Palma / Canary Islands in recent years.
The first major one occurred in October 2017, followed by another seismic crisis in February 2018. Meanwhile, 2020 has already given us 4 seismic swarms.
La Palma earthquake swarm Dec. 23-24, 2020
The latest swarm started Dec. 23rd around 9:26 p.m. and ended Dec. 24th at 9:29 p.m. local time.
Within these 24 hours, more than 602 tremors rattled the area at a depth of about 30 km with the biggest quake having a magnitude of 2.3 mbLg.
This seismic swarm is a sign of unrest… And such an increased activity has scientists going nuts as everybody knows that the collapse of this volcanic peak could kill millions of people in Europe and along Northern America’s eastern seaboard.
The video below will clearl explain to you how and why:
When will the Cumbre Vieja volcano collapse?
The collapse of the western flank of the Cumbre Vieja volcano, on the southern half of La Palma, is not going to happen tomorrow or next week without warning!
Its collapse is likely to happen any time within the next few thousand years.
How do scientists know that La Palma will collapse?
La Palma will collapse at the time of some future volcanic eruption on the summit of the Cumbre Vieja volcano. Its latest explosion was in 1949. They occur on average every 200 years. So it may last many decades before the next summit eruption takes place.
The collapse will not necessarily happen during the next summit eruption and it may well take five, ten or more explosions before the mega-tsunami.
What consequences would the collapse have?
The United States, Bahamas and the Caribbean would be severely hit by huge waves a high as 50 meters (164ft).

How to prevent the collapse of La Palma volcano?
Nothing can be done to stop the Las Palma collapse. Suitable monitoring, warning and evacuation are the best steps to prepare against this catastrophe.
Although the risk of a collapse in the next few decades is small, it will cause great destruction when it does happen.
Where are similar zones around the world?
There are dozens of large active volcanoes across the world’s oceans. Most of these have collapsed in the past, and most will collapse in the future. The latest was Anak Krakatau in 2018.
