The West Coast's volcanoes are andesitic.
They are prone to explosive eruptions, giving ash falls.
Hawaii's are a different type, prone to large lava flows.
But, there have been some events that have produced ash.
My guess is that it was on a much smaller scale than the West Coast events I've seen.
I was down in Yelm [near Olympia] when St. Helens blew.
The resulting ash cloud was over 30° above the horizon and a darker grey in color than the water clouds.
It was obvious what it was.
M'Lady and I were sitting in an Anchorage restaurant when the ash fall from Mt. Spur started.
We watched it through the window for quite a while.
Then, we drove home through it.
It was like a heavy snow fall.
Nothing on the scale of St. Helens' ash fall.
It only left about 1/4" to 1/2" on the ground.
An ash fall is highly unlikely here.
But, you might have to outrun a lava flow.
Fountains are a good possibility, like what happened in Kapoho back in the '60s.
Someone posted pics of cracks showing up in Kahukai's pavement here in Leilani.
I never took the Pahoa flow seriously, other than the possibility of being cut off from town.
So far, this one has me considering what I might need to do for a possible evacuation.
Risk keeps life interesting.

Was a Democrat until gun control became a knee jerk, then a Republican until the crazies took over, back to being a nonpartisan again.
This time, I can no longer participate in the primary.
