Detailed Description

Within hours of the Pu‘u ‘Ō‘ō crater floor collapse, HVO's monitoring instruments recorded increased seismicity and ground deformation along Kīlauea Volcano's East Rift Zone (ERZ) that continued through the night. These signals indicated an intrusion of magma from the Middle ERZ toward the Lower ERZ, extending from Pu‘u ‘Ō‘ō to at least Highway 130. This illustration shows the approximate area of Kīlauea's East Rift Zone, which, in reality, is not defined by distinct lines.
