Continued degassing from fumaroles at fissures on Kīlauea Volcano's lower East Rift Zone produce native sulfur crystals when sulfur dioxide and hydrogen sulfide gases react and cool upon reaching the surface. The delicate sulfur crystals are 5–15 mm (0.2–0.6 in) long.

The USGS Hawaiian Volcano Observatory continues to closely monitor volcanoes and earthquakes on the Island of Hawai‘i. On this map, which shows earthquakes that occurred beneath the island between August 6, 2018, and November 14, 2018, the size of each circle depicts earthquake magnitude and color indicates earthquake depth, relative to mean sea level.

Coastal storms can severely alter the topography and ecosystems along heavily populated coastal regions. Seamless integrated elevation data for both land and submerged areas in Barnegat Bay, New Jersey, are fundamental to coastal planning of the northeastern U.S. Atlantic coast.
