Landslide near Potter Hill, Anchorage, Alaska, after 2018 Anchorage earthquake.

This preliminary thickness map of Kīlauea Volcano's 2018 lower East Rift Zone lava flows was calculated by subtracting pre-eruption ground surface elevations from post-eruption ground surface elevations mapped with USGS Unmanned Aerial System (drone) flights.

High-resolution, bare-earth, airborne light detection and ranging (LiDAR) image, looking obliquely northwest into Rocky Ridge.

By processing lidar point clouds (left) to bare earth DEMs (right), the vegetation is stripped away to reveal past landslides and steep slopes at risk of failure masked by forested canopies. In dense forests, landslides--especially old landslides--might be invisible on aerial images and hard to detect from the ground.

The alfalfa leafcutting bee (Megachile rotundata) is an introduced species common to Southwest Idaho. They originate from the old world, most likely from northeastern Africa or the Middle East. These bees are successful pollinators of various crops and have been imported to North America for use in agriculture and beekeeping.

Map of selected earthquakes beneath a portion of southeast Hawai`i from May 4, 2018 to March 14, 2019, showing principally aftershocks following May 4, 2018 M6.9 earthquake. Black dots indicate epicenters of 13,083 earthquakes located during this time interval; yellow stars show locations of the M6.9 earthquake and the March 13, 2019 M5.5 earthquake.

An aerial view of the prominent 1940 cinder-and-spatter cone on the floor of Mauna Loa's summit caldera. The cone, about 100 m (330 ft) high, was built during a 134-day-long eruption that began on April 7, 1940. Most of the caldera floor around the cone is covered by lava flows erupted in 1984.
