Volcano early warning and monitoring bill discussed in Senate hearing

On September 17, Senate Committee on Energy & Natural Resources Chairman Senator Lisa Murkowski (R-AK) and Ranking Member Senator Maria Cantwell (D-WA) introduced their National Volcano Early Warning and Monitoring System Act (S.2056). On September 22, they discussed the bill in a hearing with the committee.

Volcano Disaster Assistance Program Celebrates 30 Years

EARTH: Sand Shouldn't Stand In for Volcanic Ash in Jet Engine Tests

For decades, sand has been used to simulate the effects volcanic ash may have on aircraft, but in a new study covered by EARTH Magazine, scientists used samples of real volcanic ash from volcanoes of different eruptive styles from around the world.

Interactive map of natural hazards in Nevada

The Nevada Bureau of Mines and Geology's MyHAZARDS web app provides information on earthquakes, floods, fires, and other natural hazards in interactive map form. The map covers all of Nevada, as well as portions of surrounding states for certain datasets. The map includes:

Briefing highlights role of geoscience in reducing lahar hazards

The Hazards Caucus Alliance, a network of organizations that promotes nationwide natural disaster resilience, held a briefing to highlight the role that science plays in protecting communities that are vulnerable to lahars.

NEW MAP: USGS Releases Professional Paper 1812 "Eruptive history of Mammoth Mountain and its mafic periphery, California"

EARTH: Double Trouble - Volcanic Eruption Leads to Strong Earthquake Eight Months Later

A 2002 eruption of Nyiragongo in the Democratic Republic of the Congo that killed more than 100 people also triggered an earthquake eight months later that shook the town of Kalehe in the Lake Kivu region. EARTH Magazine explores just what happened to better understand a region that is being pulled apart by plate tectonics.

EARTH: Reading the Ridges - Are Climate and the Seafloor Connected?

EARTH Magazine plunges into the depths of the ocean with scientists seeking whether Earth's climate and sea-level history are intrinsically linked with tectonics at mid-ocean ridges.

EARTH: Where Fire Freezes: All Eyes, Ears and Instruments on Iceland's Volatile Volcanoes

Iceland is located in the North Atlantic straddling a mid-ocean ridge and possibly riding over a Hawaiian-style hot spot. This makes it is a prime geological environment for volcanoes: Iceland has more than 100 volcanoes, 33 of which are active. Iceland is also home to examples of every type of volcano on Earth, each with its own eruptive pattern. Thus, the island nation presents a special challenge to volcanologists as well as serving as an ideal natural laboratory for studying how volcanic processes evolve.

Map of the surface geology of Hawaii

The United States Geological Survey's (USGS) geologic map of the state of Hawai'i provides a series of printable color maps of the surface geology for each island in the state of Hawai'i. Users can also download metadata for the maps, GIS database files, and spreadsheets of geochemical and radiometric age data for different lava flows.
