Kīlauea summit lava lake level drops with deflation
Kīlauea summit lava lake level drops with deflationJust before 10:00 a.m. today (Monday, April 30), a break in the weather allowed HVO's webcam to capture this image of the lava lake within Halema‘uma‘u at the summit of Kīlauea. Following multiple overflows of the lava lake last week, the lake level dropped over the weekend in concert with the switch to summit deflation.

Assessing the distribution and habitat needs of the least darter
Assessing the distribution and habitat needs of the least darterIsolated populations may benefit from different conservation and management activities. The least darter is a species of conservation concern that has two isolated populations occupying parts of the Arbuckle Mountain and Ozark Highlands ecoregions.

Repeated overflows onto the Halema‘uma‘u crater floor (April 27, 2018)
Repeated overflows onto the Halema‘uma‘u crater floor (April 27, 2018)This time-lapse video from 7:30 p.m. April 25 to 7:30 p.m. April 26 shows Halema‘uma‘u lava lake producing intermittent overflows onto the crater floor. The largest of these flows was from approximately 6:15 a.m. to 10:30 a.m. on April 26 and covered about 90 acres (2/3) of the crater floor.

Atoll-island groundwater
Conceptual diagram showing impact of sea-level rise and wave-driven flooding on atoll-island groundwater. (A) Current sea level. (B) Future sea level. Sea-level rise will allow for greater wave heights (H) and wave-driven runup (R), resulting in frequent overwash that will contaminate the atoll island’s freshwater lens. Note: Heights are exaggerated.
