Halema‘uma‘u crater has undergone repeated changes during the past two centuries. Prior to 1924, the size and shape of the Halema‘uma‘u lava lake changed frequently and lava commonly spilled out across the floor of Kilauea caldera.
Lavas and their minerals erupted from Hawaiian volcanoes provide clues to the history of the magmas that are eventually erupted. Kilauea’s recent summit eruptions allow us “a glimpse inside” the volcano and the chance to learn more about where the magma erupted in Halema‘uma‘u crater came from and how quickly it moved to the surface.
Lava continued to pour out of Kilauea’s summit crater Friday, one month after the latest eruption began.
The past year has seen fluctuating lava lakes, ephemeral lava fountains, craggy spires, and drifting “islands” reminiscent of pre-1924 Halemaʻumaʻu activity at the summit of Kilauea. The recent activity has USGS Hawaiian Volcano Observatory (HVO) scientists reflecting on prior observations and how they compare to recent activity.
Kilauea volcano’s summit eruption persisted for a fifth day Sunday with lava continuing to erupt from multiple vents within Halema‘uma‘u crater.
Kilauea volcano is erupting again. Wednesday afternoon, lava returned to Kilauea’s summit within Hawaii Volcanoes National Park after a 4-month hiatus. A new line of fissures sliced through the solidified crust of the 2020–21 lava lake in Halema‘uma‘u at 3:21 p.m. HST.
The eruption within Halema’uma’u crater, at Kilauea volcano’s summit within Hawaii Volcanoes National Park continued Thursday morning.
Hawaii Volcano Observatory’s scientist in charge said Tuesday progress is being made toward its new facilities.
The Pacific is home to dozens of active volcanic systems including the massive Hawaiian shield volcanoes Kilauea and Mauna Loa. Most basaltic shield volcanoes in the Pacific are related to the hotspots that created the Hawaiian Islands and many of the Polynesian and Micronesian island chains.
