The Caribbean island of Puerto Rico, a territory of the United States, is only 100 miles long by 35 miles wide—about 2 ½ times as big as Rhode Island. Even though it is a U.S. territory, Puerto Rico has its own Olympic team. The largest islands in the U.S. Virgin Islands are St. Croix, St. Thomas, and St. John.

Landsat 9 Captures Mauna Loa and Kilauea Eruption

Rare spotting! Dueling volcanoes captured by Landsat 9 satellite. Mauna Loa's 11.3-mile-long lava flow illuminates the plume of ash in the atmosphere above. The small red spot in the lower right is Kilauea—it began erupting nine days ago. USGS Volcanoes says a dual eruption has not occurred in Hawaii since 1984, making this a rare event.

On October 2, 2022, this gap-filled Landsat 7 image captured brownish-black sediment runoff from rivers and streams on the southwest coast of Florida. These are the first Landsat images after Hurricane Ian devastated the area on Wednesday, September 28. Water runoff can carry away debris, fertilizers, metals, and other pollutants.
