Flooding on the White River near Kadoka, SD, streamgage 06447000. Streamflow at this site was measured by USGS as about 26,000 cubic feet per second on May 18, 2015. Major flooding on the White River in South Dakota occurred in May 2015 following snow and rain events in western South Dakota.

Kīlauea Volcano's summit lava lake continued to drop today (May 15, 2015).

HVO webcams captured a short-lived dusty-brown plume generated by a small rock fall from the summit vent wall at 3:24 p.m., HST, this afternoon (May 15, 2015).

This sequence of HVO webcam images of Kīlauea Volcano's summit vent, recorded between 1:28 and 1:32 p.m., HST, on May 12, 2015, captures the moment a section of the dark-colored "bathtub ring" (a veneer of fresh lava that coats the vent wall as the lava lake level drops) fell into the lava lake (center).

The summit lava lake in Halema‘uma‘u Crater has dropped significantly over the past two days, as Kīlauea's summit has deflated.

A faint dusting of volcanic ash, produced by a small rockfall-triggered explosion in the Kīlauea summit lava lake on April 25, 2015, fell on this car parked near Jaggar Museum. Light rainfall afterward caused the ash to clump. USGS photo.

This satellite image was captured on Wednesday, May 6, 2015 by the Landsat 8 satellite. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures and show active lava. White areas are clouds.

The lava lake in the Overlook crater, within Halema‘uma‘u Crater at Kīlauea's summit, remains at a high level and close to the Overlook crater rim. Overflows onto the Halema‘uma‘u Crater floor have built up the rim of the Overlook crater several meters, and recent overflows are visible in the right side of the photograph.

The June 27th lava flow remains active, with breakouts focused in several areas northeast of Pu‘u ‘Ō‘ō. The farthest downslope activity observed on today's overflight was roughly 8 km (5 miles) northeast of Pu‘u ‘Ō‘ō. This photograph shows one of the active breakouts closer to Pu‘u ‘Ō‘ō.

Over the past week, the summit lava lake in the Overlook crater rose and spilled out onto the floor of Halema‘uma‘u Crater, creating the dark flows in the south part of Halema‘uma‘u (left side of crater from this direction).

A closer look at the lava lake and overflows on the floor of Halema‘uma‘u Crater. The outline of the Overlook crater, and the active lake, is easier to distinguish in this view.

From this angle, the extent of the lava lake within the Overlook crater is much easier to distinguish from the surrounding overflows. The closed Halema‘uma‘u parking lot is in the right side of the photograph.

A sequence of still images taken from the webcam positioned at the closed Halema‘uma‘u overlook, spanning about six seconds. The collapse originated from a portion of the wall directly below the webcam, but just out of view. Large pieces of molten spatter can be seen flying through the air and being deposited on the crater walls below the camera.

Following several episodes of lava overflowing onto the floor of Halema‘uma‘u Crater, the lava lake level remains high, and close to the rim of the Overlook crater. This photograph was taken from the southern rim of Halema‘uma‘u Crater, where a time-lapse camera keeps watch on the lava lake and overflow activity.

Underwater image of a wave breaking over a coral reef on Kwajalein Atoll in the Republic of the Marshall Islands. This image shows how the high hydrodynamic roughness of live, healthy corals causes friction that induces breaking of waves over coral reefs, reducing wave energy at the shoreline that can cause flooding and island overwash.
