Plate tectonics has been a centerpiece of earth science for decades, but Earth didn't always have tectonic plates. As the planet coalesced from cosmic dust approximately 4.6 billion years ago, it had a single, unbroken lithosphere. So how and when did the plates break apart and begin their seemingly never-ending round of musical chairs?
On May 9, EARTH News Editor Timothy Oleson went to check out the National Hurricane Awareness Tour's stop in Washington, D.C., at Ronald Reagan National Airport, where he sat down with National Hurricane Center (NHC) director Rick Knabb to learn more about the tour and efforts to track and forecast tropical storms.
Collecting weather data can be hazardous, but with wind speeds exceeding 200 miles per hour, flying debris, and steep gradients in both air pressure and temperature, the inside of a tornado might just be the ultimate extreme. As EARTH Magazine examines in its May issue, a team of research engineers led by Georgios Vatistas at Concordia University in Montreal is exploring this harsh environment from a safe distance by using computer models to estimate temperature changes inside tornadoes.
Leading up to Earth Science Week 2017, the American Geosciences Institute (AGI) invites you to enter its new "Earth Connections" contest. Submit a 30- to 90-second original video that tells viewers about how people have an impact on Earth systems, or how Earth systems have an impact on people, in your part of the world.
Alexandria, VA - The American Geosciences Institute (AGI) once again is sponsoring a photo contest in celebration of Earth Science Week. What’s more, the contest, which honors this year's event theme of "Earth and Human Activity," features a new twist.
A silent spring and a summer without honey? Current events have renewed interest in science that informs us about the health of our environment. In EARTH Magazine's May cover story, read about efforts to track where and how certain pesticides are making their way offsite, staying in the environment for longer than previously thought, and potentially endangering beneficial species like honey bees and aquatic invertebrates.
The following statement is attributable to Allyson Anderson Book, Executive Director of the American Geosciences Institute (AGI):
“As AGI’s Executive Director, I truly value and respect the diverse array of skills and opinions within the geoscience community."
Alexandria, VA - In celebration of Earth Science Week 2017, the American Geosciences Institute (AGI) is sponsoring four contests honoring this year's theme, "Earth and Human Activity." This year's competition will feature contests in photography, visual arts, essay writing, and video production.
As the Syrian Civil War enters its sixth year, seismic hazard might not immediately come to mind, but there is a reason it should. According to research presented at the AGU Fall Meeting, new estimates of the number of earthquake fatalities that could be expected in Turkey under several potential earthquake scenarios are 3 to 20 percent higher when Syrian refugees are counted in seismic risk models. In the April issue of EARTH Magazine, read how researchers at the University of Arkansas in Fayetteville made this discovery, which will provide vital data for disaster mitigation and response efforts.
