There are basically two kinds of termites causing problems in Hawaii: Formosan Ground Termites and Drywood Flying Termites. The former can grind their way through concrete and form large colonies (thousands of indiv.) that can weaken a wooden home in short order. I believe this is the reason why termite inspectors' reports are only valid for about two weeks; a lot can happen in that time with termites. The Drywood termites have smaller colonies (~200 indiv.) and their damage typically progresses slowly and is more limited.
The frass (dust) that they leave behind is different. The drywood termite frass looks like fluted barrels when viewed under a magnifying glass. Ground termite frass lacks the fluting. Be aware that ants can leave behind a frass-like deposit.
Ground termites don't seem to be active at higher elevations; drywood can occur at higher elevations, although to a lesser extent than at low elev.
But don't take my word for it, consult with someone who really knows what they're talking about.
