Changes On Kīlauea ERZ

The collapse of Pu‘u ‘Ō‘ō's crater floor yesterday produced a large amount of red ash that was deposited around Pu‘u ‘Ō‘ō, and a thin layer continued uprift to Mauna Ulu. This photo, taken between 1-2 km (0.6-1.2 miles) from the 61g vent, shows a layer of red ash on top of the 61g flow active surface breakouts.
