Earthquake hazards are a national risk, with nearly half of Americans living in areas prone to potentially damaging earthquakes. Learn about tools and resources that can help us all be better prepared.
U.S. Geological Survey crews are measuring flooding across Louisiana, including the Morganza and Bonnet Carre Spillways. Jennifer LaVista reports on USGS flood efforts along the Atchafalaya and Mississippi Rivers.

Video showing the collapse of the Pu'u 'O 'o crater floor on March 5. The video starts at 4 am and ends at 11 pm. The floor of the crater dropped about 115 meters (377 ft) in just a few hours.

Video showing spattering from the most persistent vent of the day just west of the base of Pu'u 'O 'o near the northeastern end of the fissure system.

This video shows lava pouring from the fissure into a seemingly bottomless crack. Napau Crater in the background. Helicopter for scale.

Video clip shot in front of the propagating fissure, showing low spattering that started moments earlier. Thick white steam from the crack in the foreground indicates that lava is about to reach the surface, and is seen doing so seconds later.

Video clip shot from the air looking SW at the fissure eruption between Pu'u 'O 'o and Napau Crater. The fissure segment in the tephra in the foreground opened seconds earlier, and only about 10 minutes after the eruption as a whole started. The cracks through the tephra are in the process of opening, though this can't be picked out at this distance.

There was a series of vent wall and rim collapses on March 3, much like those than occurred in January and February. This video, compiled from the Webcam on the rim of Halema‘uma‘u above the vent, is one of the larger collapses, and shows the northwest rim of the vent falling into the lava lake.

This clip, captured by a video camera on the rim of Halema'uma'u to the southwest of the vent, shows a small slice of the western rim of the vent collapsing into the lava lake.

The level of the lava lake sometimes changes abruptly. These cycles of rise and fall, which amount to a vertical change of around 15 m (about 50 ft), are occasionally triggered by rockfalls. Here, a small collapse from the vent wall triggers degassing and a drop in the lava level.

Booming sounds from the vent in Halema'uma'u have been audible around the summit area of Kilauea for the past several days. Some of these sounds are caused by rocks striking the surface of the lava lake, but most are actually the sound of the vent walls cracking due to heating and expansion of rock.

As spattering intensifies, the walls of the vent heat even more, causing the cracking of the rocks through thermal expansion to speed up, creating the cacophony of popping noises apparent in this video.
