The situation may change during the final week of our current visit.
Here's hoping the volcano doesn't get too active too soon.

I note there has also been a recent "earthquake swarm" at Hawaii's Kilauea volcano with tremors of magnitude 3 or less. Kilauea has been on an extended nap after erupting from 1983 to 2018.

My vague recollection of previous "earthquake swarms" caused by rising magma is, when the magma starts getting close to the surface, the quakes tend to get stronger.

Another indicator of a volcano "waking up" is increased emission of gases like SO2. Such emissions can combine with humidity in the air to form "vog," which might further impede visibility.
