Kīlauea Volcano's lava lake within Halema‘uma‘u Crater rose steadily over the past day in concert with summit inflation. This morning, with the lake level at just 19 m (62 ft) below the summit vent rim, vigorous spattering on the lake surface was visible from the Jaggar Museum Overlook in Hawai‘i Volcanoes National Park.

Ernie Valdez’s research is generally focused in the western United States but has extended as far west at the US Territory of the Northern Mariana Islands.

During the symposium, participants could tour the facilities at Woods Hole Oceanographic Institution, such as this radiocarbon lab. Here scientists analyze the amount of radiocarbon in such material as coral or wood to help determine their age. Photo credit: Amy West, USGS Pacific Coastal and Marine Science Center
