Off topic CSB but my folks spent two months on a private island in Hawaii for their 50th wedding anniversary in 2018. My mother spent the entire time complaining about how dark and grey and even slightly chilly it was for most of their visit because Kilauea was actively erupting and really had to be walked through how no one on planet Earth had to power to do anything about that, no matter how much her trip cost.
Lava is really humbling. I don't know of anything that stops it, or even affects it, short of a nuclear bomb. The only good news is, at least on the Big Island, it doesn't move at high speed. The only thing that slows and finally stops it is water. But, it takes a LONG time.
We have been lucky that none of the Hawaiian Islands have done a Krakatoa:

The volcanic activity continues there...
