| good idea, but some suggestions. first, a cyclone and hurricane are synonymous...same phenomenon, different names for different regions...I would combine those, and also accept typhoon if it isn't already. secondly, wikipedia only lists heat wave, but I'm not sure why a cold wave wouldn't be considered as well. perhaps call it 'extreme temperatures' and accept both heat and cold wave? I don't know how I feel about including lahar...since its so closely connected to a volcanic eruption and landslides...kind of a combination of the two, but that's just my opinion, i suppose its inclusion can be justified. |
