Photo of Kīlauea's 2018 lower East Rift Zone eruption fissure 7, from Hookupu street and looking west. The rampart is surrounded by fissure 8 lava. This view is of the back side of the rampart; lava fountains erupted on the opposite side of the rampart.

In Russia's Extreme North, a widening chasm known as the Batagaika Crater provides a unique opportunity to study the past. Early declassified aerial images recorded the crater's growth in the 1960s and 1970s followed by multispectral sensor imagery captured by Landsat and Sentinel satellites, building a continuous view over the last 60 years.

Still images from videos of surface water flow overlaid with velocity vectors during low (top) and high (bottom) flow conditions in Frankford Creek, Philadelphia, Pennsylvania, September 2020. These videos were processed using large-scale particle imaging velocimetry (LSPIV) to estimate streamflow in a location where standard methods are inadequate.

The UNAVCO-operated geodetic infrastructure located in Yellowstone National Park consists of over a dozen continuously operating geodetic sites. Most of these sites stream real-time data to the UNAVCO data center. After the September 2020 maintenance trip, there are now 8 fully upgraded GNSS sites (red square) located in the park.

This Coastal Change Storm Hazard Team forecast was made at 4 AM CDT August 26, 2020 and shows forecast beach erosion at the base of the dunes (the strip of colored bars closest to the coast), overwash (middle strip) and inundation (outer strip) from Hurricane Laura. The model accounts for sandy beaches and barrier islands and does not include marshes,
