  1. Story courtesy WUWT: Hawaiian scientists identify the largest shield volcano on earth. This one is down the chain a bit and appears to be 5x the size of Mauna Loa. Age is around 14 Ma. Not much of it remains above the waves. Speculated cause is a hotter than normal chunk of underlying mantle plume. Cheers –
