On Friday afternoon, three areas of spattering on the summit lava lake surface produced abundant volcanic gas emissions, one of the main hazards near the Halema‘uma‘u Crater vent. Earlier this morning, spattering lava was visible from a safe distance at Jaggar Museum Overlook in Hawai‘i Volcanoes National Park.

In July of 2016, a team from the Climate and Land Use Research and Development Program took a trip to South Carolina to study outcrops of the “Canepatch” and “Socastee” formations along the Intra-Coastal Waterway, near Myrtle Beach. The age of these fossiliferous marine units has been controversial for several decades.

Perched on the rim of Kīlauea Volcano's summit caldera, the USGS Hawaiian Volcano Observatory and NPS Jaggar Museum (foreground) overlook the active lava lake within Halema‘uma‘u Crater. The black lava flows to the left and right of the fuming vent spilled onto the crater floor in April-May 2015, when the lava lake briefly filled to overflowing.

The active lava flow on Kīlauea Volcano's south flank providing wonderful lava-viewing experiences for Park visitors. A section of the road can be seen here, with fume from the active lava tube in the far distance behind it, and the active flow front in the foreground. The flow front was less than 100 meters (yards) from the ocean when this photo was taken.
