Kīlauea summit eruption in Halema‘uma‘u - June 7, 2023

A summit eruption of Kīlauea volcano, within Halemaʻumaʻu crater, began at approximately 4:44 a.m. on June 7, 2023. Lava is flowing on the crater floor and there are several active vent sources. The eruption at Kīlauea’s summit is occurring within a closed area of Hawai'i Volcanoes National Park and high levels of volcanic gas are the primary hazard of concern.

Smallmouth Bass are good indicators of methylmercury exposure to humans and wildlife because they are a common, popular sport fish and eat a variety of food during their lifetime. Juvenile Smallmouth Bass – smaller than 150mm in length - eat zooplankton, or microscopic animals.

When disaster strikes, near-real-time images of its effects can be invaluable. In this episode of Eyes on Earth, we learn about how a newly developed system using the Harmonized Landsat Sentinel-2 dataset and artificial intelligence was put to the test when Hurricane Ian tore through Florida in late September 2022.
