The crater of Hawaii’s Kilauea volcano has nearly doubled in size within the last month as its eruption shows no sign of slowing. The United States Geological Survey (USGS) is monitoring activity as scientists try to work out what will happen next – so what is going on at the Halema’uma’u crater?  The scientific agency said:

“Magma in the summit magma chamber has drained over the past month due to the Lower East Rift Zone eruption, causing much of the floor and rim of Halema’uma’u to drop or collapse. “These changes have resulted in a much deeper crater, with rubble covering the floor.” The deepest part of the crater is now 280m, which reaches below the previous crater floor.
