Oak is most definately a hardwood. Poplar is is somewhat hard, but is most reknown for its ability to to be finished to look like other woods.Any number of hardwoods have open pores. Oak, Rosewood, Teak to name a few. The closed pore hardwoods: cherry, walnut, maple, ash, etc. are just that closed pore hardwoods.
By contrast pine and fir ar closed pore woods but are considered to be softwoods. The pores have absolutely nothing to do with the hardness of the wood.

Follow Ups:
Oak is an open-grained wood, Poplar very closed-grained. Both are, I would say, medium-high density. As you said, character of grain has nothing to do with density.I picked Oak and Poplar because they are available widely and reasonably, have some density, and especially because both are nonresonant, you rap them and get 'thunk' rather than 'ping'.
Yes, Brazilwood (S A Rosewood) and Cocobolo are among the most open-grained (open pored, actually) and high density woods I know of. They are also highly resonant; both are used for xylophone keys.

Heard that on Maui, things were really rattling.
Hope nothing valuable got damaged.

I don't believe they made such a big deal out of it. The big island is the next one over; I was standing in my bedroom when I heard the dishes start to rattle in the cupboards, and went out in the kitchen to hold the doors shut. It was a bit of a dance for fifteen seconds or so, but I didn't have any trouble keeping my feet. Classic pattern; first sharp little jerks, then smoothing out into an ocean wave sort of rock.I think the reason we lost so much power is that it's been so long since the last one, about fifteen or twenty years. We used to get them every few months or year, and they would get about ten seconds on the local news. Come to think of it, they stopped about when Kilauea Iki started spouting real consistently. I wonder if Pele is getting ready to move house.
A funny thing; there was absolutely no howling of cats and dogs before. That's usually the first warning - it must have started real suddenly, had no preshocks.
Thanks for your concern,
Poinz
