Lava fountains from the June 3, 2024 fissure eruption in Kīlauea's Southwest Rift Zone were estimated to have reached as high as 20 meters (66 feet), with an average height of 10 meters (33 feet).

Scientists observed cracks in previous eruptive surfaces near the new fissure eruption southwest of Kīlauea's summit on June 3, 2024. These cracks ranged from a few centimeters (inches) to approximately 2 meters (6.6 feet) wide.

A new eruption began along Kīlauea's Southwest Rift Zone on June 3, 2024, and this map depicts activity on the eruption's first day. New lava flows are shown in red, only covering about 88 acres (36 hectares) of ground within relatively short distances of the eruptive fissures.

Frothy, glassy fragments of lava from the fountains of Kīlauea's June 3 eruption fissures were found scattered around newly-erupted lava flows. These tephra contain valuable geochemical information about the magma which fueled the eruption. USGS image by D. Downs.

How Streamgages are Used in Postfire Flood Forecasting
Stream data is recorded in real time and posted online.
Stream data include water level, velocity, and turbidity.
During storms, rainfall data is compared to the stream data.
The National Weather Service uses the data to issue flood warnings.

During the March 21, 2024 lahar evacuation drills, thousands of students walked to the Washington State Fairgrounds in Puyallup, Washington to practice evacuating from a lahar generated by Mount Rainier. A lahar, or volcanic mudflow, could reach this area in about 3 hours.
