A huge chunk of the Cumbre Vieja volcano, on the Canary Island of La Palma, is on the move. In 1949, this mass of rock - perhaps as large as the Isle of Man - dropped 4 metres seawards and stopped.
Monitoring in the mid-90s suggested that it was continuing to creep downslope, though only at a centimetre or so a year. At some time, however, and we don't have a clue when, the landslide will plunge into the north Atlantic, generating gigantic tsunamis - sea waves likely to be 50 metres high or more - that will devastate the Caribbean and eastern United States, as well as the Canaries themselves, southern Europe and western Africa.
Without evacuation, the destruction will end the lives of tens of millions and bring the global economy to its knees overnight.
You might expect that this landslide would be one of the most closely studied on the planet, but that would be far off the mark. In reality, nobody is monitoring the situation, and the island's authorities are reportedly allowing new building developments to go ahead.
I think this author lacks perspecitive in that many scenarios offer little hope, or much that can be done, but I found the article to be interesting.
