This is almost completely correct. However, I have heard of one other possibility that might be a problem - a steam explosion (maar).

From what I understand, a person died falling in a crack in town earlier this week, and when they went down to investigate, they found ocean water in it. There is a possibility (albight slight) of magma finding it's way into such cracks and causing a steam explosion. Nothing on the scale of something like what happened at Hunga-Haapi earlier last year, but still a not-so-great explosion.
