In this episode of Outstanding in the Field, we take you to the swamps and coastal wetlands of Louisiana, the land of bayous and beignets and a state with one of the most dynamic coastlines in the United States. The wetlands that make up the Louisiana coast are vast and help protect important cultural and natural resources.

The good news is that volcanoes usually change behavior before they erupt, in ways that are detectable by monitoring instruments.

The lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, remains active, as seen in this view looking north. Active surface lava is limited to the western (left) portion of the lake between the main island and the western fissure complex. The blueish tinge to the plume from the western fissure complex (left) is due to sulfur dioxide (SO2).

This map of Halema‘uma‘u at the summit of Kīlauea shows 20 m (66 ft) contour lines (dark gray) that mark locations of equal elevation above sea level (asl). The map shows that the lava lake has filled 225 m (738 ft) of the crater, to an elevation of 742 m (2434 ft) asl since the eruption began on December 20, 2020.

A telephoto image from the ongoing eruption within Halema‘uma‘u crater at the summit of Kīlauea. Lava continues to enter the lava lake through an inlet near the base of the west vent cone (right). An incandescent opening near the top of the cone (upper center), ejected occasional bursts of spatter.

A telephoto view of the eastern Halema‘uma‘u crater wall and portion of the crusted-over lava lake at Kīlauea summit. In this photo, molten lava from below the surface crust has squeezed up between the lava crust and the crater wall as an “ooze-out.” USGS photo taken by L. DeSmither on April 2, 2021.

A wide view of the eruption within Halema‘uma‘u crater at the summit of Kīlauea. The western vent and perched lava lake remain active in the western portion of the crater (left). Sulfur dioxide emission rates remain elevated, with the most recent measurement being 1,200 tonnes per day on April 1. USGS photo taken by L. DeSmither on April 2, 2021.

Telephoto image of the western cone complex of the current eruption in Halema‘uma‘u at Kīlauea's summit. In the center, a horseshoe-shaped spatter rampart is partially filled in by a more recent spatter cone. The cone has an incandescent opening that spatter is occasionally erupted from.

This March 31, 2021, photo shows a close-up view of the active western fissure of Halema‘uma‘u at Kīlauea volcano on the Island of Hawai‘i. Near the bottom of the photo, orange incandescence can be seen from two circular vents of the spatter cones.

This is an animation showing the changing conditions of USGS streamgages from January 1, 2021 to March 31, 2021. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.

There are thousands of volcanic features distributed throughout the southwest United States, which are grouped together in volcanic fields. The Yellowstone Volcano Observatory monitors these volcanoes using a combination of techniques.

A mudslide near the 2020 Dolan Fire's ignition point chopped through a chunk of California's scenic State Highway 1 in late January.
The Dolan Fire began near Big Sur on August 18th, 2020. It scarred nearly 125,000 acres before being fully contained in December.

Map of Yellowstone’s thermal areas. Thermally active thermal areas (known to have thermal features with above-background temperatures) are shown in red. Inactive and cold, degassing thermal areas are shown in blue. Areas that are unknown or inconclusive in terms of their thermal activity are shown in purple.
