Detailed Description

Since early May 2018, the floor of Halema‘uma‘u Crater has dropped 450 m (about 1480 ft). Extensive cracking and faulting around the crater, and the inward slumping of the crater rim has more than doubled its diameter. Like a balloon slowly losing air, subsidence occurs because magma in the shallow summit reservoir is moving into the East Rift Zone more rapidly than magma is being supplied from depth. Images collected during a helicopter overflight of the summit area on July 13, 2018 were used to produce this digital elevation model showing current conditions.
