Solid, Liquid, Gas, Plasma

I'm sure others have noticed this - the four classical elements/states of matter are Earth, Water, Air and Fire.

Earth - Christchurch Quake
Water - Floods in Hawkes bay
Air - Tornado in Auckland

That just leaves Fire. Umm, wasn't there a story recently that Ruapehu was showing signs of "elevated unrest".

ETA: Clearly I'm not the only one thinking this way - Moata has a smorgasbord of disasters today
