Viewing conditions into Pu‘u ‘Ō‘ō Crater were exceptional today, providing clear views of the crater floor. This view is towards the northwest. The inner, deeper crater formed in mid-2014 following the opening of the June 27th vent, and occasional small flows on the crater floor are evident by their dark color.

A closer view of Pu‘u ‘Ō‘ō, just above the center point of the photograph. View is towards the southwest. In the foreground, the circular lava pond that was active in July 2014 is visible. The lava tube feeding the active flows on the June 27th lava flow is evident by the line of white fume sources extending off the right side of the photograph.

In late 2015/early 2016 unusually large rainfall in the Upper Mississippi River Valley led to significant flooding in Arkansas, Illinois, Louisiana, Mississippi, Missouri, and Tennessee. USGS crews responded to the flooding by collecting streamflow and water quality information and providing it to emergency responders.

A panorama of the floodwaters at the Bonnet Carré Spillway. In preparation for the river crests due next week, USGS is out sampling on the Bonnet Carre Spillway, one of two spillways on the Mississippi River operated by the U.S. Army Corps of Engineers.

Flooded land within the Bonnet Carré Spillway. Normally, this land is dry, but when the U.S. Army Corps of Engineers decides to release Mississippi River water from the Bonnet Carré Spillway, this land will be submerged.

Mississippi River water flows through the Bonnet Carré Spillway into the channel, where it will flow to Lake Pontchartrain.

Though the park celebrates its 100th anniversary on August 1, 2016, its main attractions-Kilauea and Mauna Loa volcanoes-have been adding to the land mass of Hawaii’s “Big Island” for at least 400,000 years.

Preview image for video: A rockfall on the east rim of the summit vent within Kīlauea Volcano's Halema‘uma‘u Crater triggered a small explosive event at 3:51 a.m., HST, on January 8, 2016. Explosive events like this occur more frequently when the lava lake level is relatively high, as it has been this past week—around 30-35 m (100-115 ft) below the vent rim.

In recent days, the lava lake in Halema‘uma‘u Crater has been at a relatively high level. This view, looking roughly north-northeast, shows typical behavior, with lava rising into the lake at the distant end opposite the photographer, and sinking all along the base of the crater wall in the foreground and at right.
