I've been to Guadalcanal. There's not a lot to damage, unless they've really built up in the last 20 years.
Key for quakes is to either be really advanced such that you're building high-quality buildings specifically engineered to be quake-proof, or so backwards theres hardly anything to fall on you.
Worst is 2nd world/3rd world shoddy concrete lowrise construction, like Pakistan, Turkey, Armenia, etc.
