Click on the title for the preliminary report. The map at http://tux.wr.usgs.gov/ should have a location soon. It was a 3.4 magnitude (although it didn't feel quite like it at my place) up around Hualalai, the volcano overlooking Kailua.
This is the Hawaiian Lionfish Pterois Sphex. It looks a heck of a lot like an antennata lion (pterois antennata - aka spotfin lion) that I used to sell back in the days I had my aquarium shop. It's pretty much just missing some spots over the fins and I'm sure there are other differences those who are into classification would notice.
I've not mentioned my former days as an aquarium shop owner... no wonder I love scuba. Nowadays I just dive to get my fish fix. I can't see having an aquarium anymore personally when I can just go down the hill and be immersed in it.
