Ice jam on the White River near White River, SD (USGS streamgage 06447450) on March 15, 2018. Ice jams occur when floating ice carried with a stream’s current accumulate at any obstruction to the stream flow. These ice jams can develop near river bends, mouths of tributaries, areas of decreased river slope, and upstream of obstructions like bridges.

Just before noon today, HVO's summit webcam (KIcam) captured this striking image of Kīlauea Volcano's ongoing summit eruption. A small rockfall on the north side of the Overlook crater triggered a small explosion in the lava lake, sending a dark-colored ash plume skyward.

Hot springs can occur in many parts of the world. The water is hot not due to climate, but rather due to geothermal activity underground, such as volcanic activity or active hydrothermal heating from hot material in the ground. Hot springs result from water heated by underground geothermal activity finding its way to the land surface.

On November 5, 1967, a line of vigorous lava fountains erupted on the floor of Halema‘uma‘u at the summit of Kīlauea. Lava soon covered the entire crater floor as volcanic gases billowed skyward (aerial view). Near the center, a pool of molten lava repeatedly overflowed a levee of crusted lava, spilling flows onto the lava-covered crater floor (inset).
