A plume of sediment flows into the northern Chesapeake Bay after several days of heavy rain in the Mid-Atlantic last week. This side-by-side image from the NOAA/NASA Suomi NPP satellite shows the Chesapeake Bay on July 19 and July 26. In the left hand image, the land appears brown due to dry conditions that dominated the first half of July.
This multi-day infrared imagery from the NOAA-20 and Suomi NPP polar orbiting satellites shows the dangerous wildfires that continue to torch parts of Northern California. In the first four days of July, the County Fire nearly doubled in size, and can be seen here encroaching upon the eastern shore of nearby Lake Berryessa. Since the fire began on June 30, it has burned 86,000 acres and is about 30 percent contained, according to the California Department of Forestry and Fire Protection (Cal Fire).
The Suomi NPP satellite's VIIRS instrument captured this image of the Fuego Volcano eruption in Guatemala on June 3, 2018. Despite numerous clouds overhead, the dark ash cloud is easily distinguishable in the center of the image. Known locally as "Volcán de Fuego", or "Fire Volcano," the 12,340 foot stratovolcano is one of the most active in Latin America, located about 27 miles from the capital, Guatemala City. While the volcano erupted as recently as February 2018, the latest event has been far more catastrophic.
The Suomi NPP satellite's VIIRS instrument captured this detailed thermal imagery showing the eruption of Hawaii's Kilauea Volcano on May 4, 2018. Clear skies over the eastern portion of Hawaii's Big Island reveal the site of the Pu‘u ‘Ō‘ō Crater, which began erupting after multiple earthquakes jolted the island last week – including a 6.9-magnitude tremor on May 4.
Plumes of sediment flow into the Gulf of Mexico at the mouth of the Mississippi River in this image seen by the Suomi NPP polar-orbiting satellite on April 16, 2018. Heavy rainfall from last week's powerful storm moving over the Mississippi Valley caused the river and its tributaries to swell, carrying large amounts of mud and sediment downstream.
This image, captured by the Suomi NPP satellite's VIIRS instrument on April 15, 2018, shows locations of burn scars from the active wildfires currently burning across western Oklahoma and northern Texas since last week. Hot, dry weather and gusty winds triggered the fires, which have now charred more than 300,000 acres in Oklahoma alone. The Rhea Fire, which began April 12, has burned 242,000 acres and has killed two people, according to media reports.
The Suomi NPP satellite captured this clear-sky view of the Volga River Delta and the northern Caspian Sea on April 9, 2018. Straddling the border of southern Russia and western Kazakhstan, the Volga River Delta is the largest inland river delta in Europe. The river flows into more than 500 channels as it drains into the sea, where nutrients from upstream create a thriving wetland ecosystem. The turbulent, dark green water at the southern tip of the Volga River Delta is a result of mud carried downstream from spring rains and melting snow.
