Ohio River at Olmsted IL - equipment damage

Streamflow measurement at Milk River near Harlem, Montana

Beginning around midnight on Saturday, April 21, Kīlauea Volcano's summit lava lake rose high enough that lava briefly spilled onto the floor of Halema‘uma‘u. Since then, additional overflows occurred in four pulses on April 22-23. The largest one occurred during the fourth pulse, which started at 6:30 a.m.

Overflows from the perched lava pond within west pit, a small crater adjacent to the main Pu‘u ‘Ō‘ō crater on Kīlauea Volcano's East Rift Zone, continue to build up the levees around the pond. The rising level of the perched lava pond during the past month is a sign of the increasing pressure within the magma system beneath Pu‘u ‘Ō‘ō.
