Americas East Coast Megatsunami Canary Islands Geologists S. Day and S. Ward consider that a megatsunami could be generated during a future eruption involving the Cumbre Vieja on the volcanic ocean island of La Palma, in the Canary Islands.[12][13]

In 1949, the Cumbre Vieja volcano erupted at its Duraznero, Hoyo Negro and San Juan vents. During this eruption, an earthquake with an epicentre near the village of Jedy occurred. The following day Rubio Bonelli, a local geologist, visited the summit area and discovered that a fissure about 2.5 km long had opened on the eastern side of the summit. As a result, the western half of the Cumbre Vieja (which is the volcanically active arm of a triple-armed rift) had slipped about 2 m downwards and 1 m westwards towards the Atlantic Ocean[citation needed].

The Cumbre Vieja volcano is currently in a dormant stage, but will almost certainly erupt again in the future. Day and Ward hypothesize[12][13] that if such an eruption causes the western flank to fail, a megatsunami will be generated.

La Palma is currently the most volcanically active island in the Canary Islands Archipelago. It is likely that several eruptions would be required before failure would occur on Cumbre Vieja.[12][13] However, the western half of the volcano has an approximate volume of 500 km3 (5 x 1011 m3) and an estimated mass of 1.5 x 1015 kg. If it were to catastrophically slide into the ocean, it could generate a wave with an initial height of about 1,000 metres (3,281 ft) at the island, and a likely height of around 50 metres (164 ft) at the Caribbean and the Eastern North American seaboard when it runs ashore eight or more hours later. Tens of millions of lives would be lost as New York, Boston, Baltimore, Washington D.C., Miami, Havana, and many other cities near the Atlantic coast are leveled. The likelihood of this happening is a matter of vigorous debate.[14]

The last Cumbre Vieja eruption occurred in 1971 at the southern end of the sub-aerial section without any movement. The section affected by the 1949 eruption is currently stationary and does not appear to have moved since the initial rupture.[15]

Geologists and volcanologists also disagree about whether an eruption on the Cumbre Vieja would cause a single large gravitational landslide or a series of smaller landslides.

  • I live in the mountains of Va., 300 mi miles from the coast. How far inland would the water travel?? Just want to make sure my family is safe.

  • Nature is being uprooted in its Place by the shifting of the Poles and this Vulcano is a deadly dangerous reminder that our meaningless and shallow Lives can come to an end at any Time! nature is taking back her Beaches and is expelling the people who have bought up Beach Property and are greedily keeping Non Owners away from the beaches! If this becomes reality we will be in deep shit!

  • @MrSpemat No one believed the "It could happen tomorrow" scenario of New Orleans flooding either! And yet it did!

  • Fear mongering

  • And in the lylat system, andross continues to attack corneria

  • @dkrustyklown Actually, there is a way to do it without drawing to much attention to yourself. Ammonium nitrate is used by farmers the world over. You could ship the ammonium nitrate and nitromethane fuel in small shipments to La Palma over many months. And it wouldn't take 1,000's of tons of explosives. The trapped water in the mountain would act as a catalyst by turning to steam. The pressure from the steam would do the job just fine.

  • These Tsunamis are caused by terrorists(you know, Muslims, who else can terrorists be) who are praying to Allah to punish US because they are jealous of democracy and freedom in US. They are also angry you drink too much Jack Daniels every Friday.

    Now all said according to your IQ level, you can have a good night sleep now.

  • @obekiro99 It would take thousands of tons of ammonium nitrate/fuel explosives to pull this off. Don't you think that the people that live on the island and the Spanish government would notice the sudden arrival of thousands of tons of fertilizer and fuel on the volcano? There's just no subtle way to do it.
