Tephra layers preserved at the summit of Kīlauea from at least three different eruptions. Deposits below the top of the scale are predominantly juvenile and deposits above it containing many lithics. Notice the larger size of the yellow pumice clasts compared to the much denser and finer grey lapilli and ash surrounding them from 7 to 18 on the scale.

Map of southeastern Idaho showing volcanic rocks related to the Yellowstone hotspot. Basalt is shown in red and rhyolite in yellow. Blue circles indicate the location of past Yellowstone calderas; caldera names and approximate ages are shown (Ma = million years old).

Tropical Storm Eta affected beaches along Florida's Gulf Coast in November 2020. Some dunes were eroded up to several feet due to the high water levels associated with the storm. Madeira Beach is home to many people and animals, and erosion events such as this can affect both habitat and infrastructure.

Year-long (August 2017 to August 2018) temperature records from two hydrothermal vents (“A” and “B”) in the Deep Hole area of Yellowstone Lake.

Dark brown colors dominated the central and western portions of the lake at Kīlauea's summit. The greenish hues were present in areas that appear to be zone of hot water influx into the lake. USGS photo by M. Patrick.

A quick visit to the western caldera rim provided brief views of Kīlauea's summit lake between rain showers. The lake colors were particularly vibrant today, with a deep blue-green color in the western end (bottom of photo), with dark brown near the center. USGS photo by M. Patrick.

Tropical Storm Eta had effects on Florida's Gulf Coast beaches, including dune erosion and overwash. This image from the coast cam at Madeira Beach, Florida captured high water levels and resulting overwash of sand onto the patio of the Shoreline Resort.
