From the Uēkahuna overlook, the new eruption at the summit of Kīlauea is visible. The farthest east fissure is near the to margin of downdropped block that formed during the 2018 summit collapse. The base of the main fissure, which is farthest west (right on the image), is approximately 70 meters wide.

An eruption at the summit of Kīlauea volcano began on September 10, 2023. The main fountain, which HVO geologists estimate is approximately 50 meters tall, is on the eastern margin of Halemaʻumaʻu crater. As of approximately 4:30 p.m.

TYPES OF LANDSLIDES
Lateral spreads are distinctive because they usually occur on very gentle slopes or flat terrain. The dominant mode of movement is lateral extension accompanied by shear or tensile fractures.
