Kīlauea caldera with people for scale

10:29 PM · Apr 27, 2023

The scale of the Kīlauea caldera is something you really need to see in person, but this kinda gives a sense of it. Edited image from USGS-HVO: "Three orange-clad geologists from the Hawaiian Volcano Observatory can be seen in this image (in orange, near center of image). During a visit to Halema‘uma‘u crater the morning of April 21, 2023, the geologists collected tephra samples from the Uēkahuna bluff along the northern wall of Kīlauea's summit caldera. Kīlauea has a history of explosive eruptions—the evidence for these events is contained within the many layers exposed along this part of the volcano. USGS image by L. Gallant." We will be live with our weekly Tracker volcano update LIVE at 5pm HST this evening to go over the latest on Kilauea and the recent earthquake activity right here on Hawaii Tracker.
