Kīlauea's summit eruption continues on the Island of Hawai‘i; Halema‘uma‘u west vent erupts lava into the lava lake, which was 226 m (741 ft) deep this morning, April 13. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear—monitor the eruption from within the closed area of Hawai‘i Volcanoes National Park with NPS permission...

The USGS recently published a data release that includes a three-dimensional model of Puʻuʻōʻō, on Kīlauea's East Rift Zone, and the collapse crater, constructed from aerial thermal images collected on 11 May 2018.  Structure-from-motion processing was used to create the model from the sequence of oblique images, and ground control using kinematic GPS was used to georegister the model.
