(Top) Methane plumes at the Norfolk Canyon seeps (~1600 meters or 5250 feet) were detected using the EK60 sonar. The water column plumes are shown above the sub-seafloor structure as imaged by high-resolution multichannel seismic data acquired by the USGS and processed by J. Kluesner.

Happy birthday Pu‘u ‘Ō‘ō! A look back at what happened in 2018
Happy birthday Pu‘u ‘Ō‘ō! A look back at what happened in 2018Glow from an active ocean entry on Kīlauea Volcano's Kamokuna lava delta was visible on the evening of September 27, when the 2017 delta was near its maximum size of 8-10 acres. Since then, the edges of the delta began to crumble into the sea. With no lava entering the ocean since November, ocean waves slowly erode the lava delta, further reducing its size.

Evolving tube network blocked and diverted lava from Kamokuna delta
Evolving tube network blocked and diverted lava from Kamokuna deltaThermal map of the 61g lava flow, created on December 12, 2017. The thermal map is limited to the current flow (episode 61g flow), which runs along the center of the map. The blue and green colors correspond to lower surface temperatures, areas of cooled, inactive lava.

Geologist examines spatter and ash deposits within Hawai‘i Volcanoes National Park along Kīlauea's southwest rift zone. New understanding of the age of the ash deposits, based on years of careful research, has prompted an important revision of the ages of these surface lava flows.
