A lot have carefully studied Cumbre Vieja and many people have roundly debunked the scare stories which fostered a bunch of sensationalistic documentaries - however,
1) while scientific journals have reported on this, the MSM has not
2) a lot of people on the internet got off so much about fantasizing about Cumbre Vieja wiping out the East Coast they don't bother to look at any of the counter-evidence.

Thanks for good links. It's nice to know responsible geologists have already done the appropriate work.
After all, is anyone going to tune into the documentary about how an eruption there won't cause a tsunami?
It's no different than the constant scare mongering over Yellowstone.
