ESI: News and Information

Sep 13, 2019
In the Davis Mountains of far west Texas, at the University of Texas McDonald Observatory, astronomers spend their nights peering at the stars through some of the world’s most powerful telescopes. Soon they’ll be adding a more down-to-Earth job. Within sight of the giant domes, NASA is installing a... Read More

On May 29, 2006, hot mud and gas began gushing from a rice field near a gas exploration well in East Java. More than a decade later, the Lusi mud flow continues on the Indonesian island. (The name is a combination of lumpur, the Indonesian word for mud, and Sidoarjo, the location of the flow). Over... Read More

It is increasingly rare to find new large impact craters on Earth, let alone such craters buried beneath ice. This study by MacGregor et al. describes a possible impact crater buried beneath two kilometers of ice in northwest Greenland. The circular structure is more than 36 kilometers wide, and... Read More

Dispersed across the Sahara Desert in northern Niger, the Aïr Mountains rise sharply from the low-lying sea of sand to provide unique scenery, aesthetically and geologically. The mountain range hosts volcanic peaks, is traversed by deep valleys, and makes up one of the world’s largest ring dike... Read More

The Hiawatha impact crater was first suspected to exist in the summer of 2015, from examination of a compilation of Greenland's sub-ice topography radar measurements made by NASA over two decades. The visualizations of the subsurface shown below are derived from a spring 2016 airborne survey by... Read More

Though Kilauea has been erupting continuously from the Pu’u O’o vent since 1983, the eruption took a dangerous turn on May 3, 2018, when new fissures opened in the residential neighborhood of Leilani Estates. Three weeks later, some fissures have become less active but several... Read More

NASA scientists used GRACE data to identify regional trends of freshwater movement, and combined that information with data from other satellites, climate models and precipitation measurements to determine the causes of major regional trends in freshwater storage. In these visualizations, the... Read More

You have probably seen dramatic images and videos of several new fissure eruptions cracking open the land surface in Hawaii, emitting plumes of gas, and spitting up fountains of lava in the middle of a residential neighborhood. If you are tracking Kilauea’s eruptions, the U.S. Geological Survey...

It is one of the most famous patches of coral outside of the Great Barrier Reef. Stretching a mere 7.5 kilometers (4.7 miles) by 2.5 kilometers (1.6 miles) and surrounded by deep ocean, it is barely a speck on world maps. Though uninhabited today, Nikumaroro atoll is noteworthy for someone who... Read More

Indonesia’s Mount Sinabung has been sporadically active since 2010, following four centuries of quiet. On February 19, 2018, the stratovolcano on the island of Sumatra erupted violently, spewing ash at least 5 to 7 kilometers (16,000 to 23,000 feet) into the air over Indonesia. At 11:10 a... Read More
