There was speculation in an article a couple days ago of possible landslide collapse into the ocean of one side of the island near the volcano (due to the eruption and all the earthquakes the proceeded it, as well as those still going on) and that possibly causing a large tidal wave - https://www.nzherald.co.nz/world/canary-islands-volcano-could-eruption-cause-landslide-and-mega-tsunami/MEAOBU6BPNYO7QPCIWCNOHVU7A/
But then the "disaster scenario" was apparently pooh-poohed based on some later studies.
Here's an interesting explanation about it though from 4 years ago -
Currently 76 with dp way down to an amazing 49. I did have to go out and water because despite some 11" of rain last month, and except for a few hundredths of an inch the past couple days, I haven't had a solid rain since around September 9th.
