Although no one can reliably predict earthquakes, today’s technology is advanced enough to rapidly detect seismic waves as an earthquake begins, calculate the maximum expected shaking, and send alerts to surrounding areas before damage can occur. This technology is known as “earthquake early warning” (EEW).
Earlier this year, Apple’s iPhone celebrated the 10th anniversary of its introduction to the world, an event that fueled a transformation within the technology and communications sector. This revolution would influence billions of smartphone users around the world forever altering many aspects of human life.
On an ordinary Tuesday in 2014, David Pineault, an economist at the Defense Logistics Agency (DLA), reviewed his specialized reports and came to a startling conclusion: the United States needed to increase its stockpile of a basic manufacturing material with military applications—yttrium oxide, a material used in laser rangefinders.
Hours before Japan was struck by the 2011 Tōhoku earthquake and the ensuing catastrophic tsunami, John Schelling spoke at a public meeting in the coastal community of Oceans Shores, Washington, about preparing for tsunami hazards. The few dozen people attending the meeting went home that evening and watched in horror as the events in Japan unfolded.
The Colorado River system provides about 35 million Americans with a portion of their water supply. It irrigates 5½ million acres of land in the West and provides water to tribes, parks, and wildlife. The system serves parts of seven States and Mexico—but reservoir levels have crept lower over the past several years, sparking questions about how much water remains and who will have access.
The water in the Delta arrives primarily from the Sacramento and San Joaquin Rivers, supplying water for more than 22 million people. This water source supports California’s trillion-dollar economy—the sixth largest in the world—and its $27 billion agricultural industry.
Groundwater, which flows out of sight through aquifers beneath our feet, is one of the Nation’s most important natural resources. In recognition of National Groundwater Awareness Week, March 5–11, 2017, here’s an opportunity to put your knowledge of this vital resource to the test!
Nitrogen and phosphorus are essential nutrients—yet too much of a good thing is not always a good thing. Scientists are investigating nutrient pollution down the Mississippi River.
Bogoslof volcano, located in the Aleutian Islands about 98 km (61 mi) northwest of Dutch Harbor/Unalaska, is in an active eruption sequence that began in mid-December 2016 and continues today.
New USGS maps identify potential ground-shaking hazards in 2017 from both human-induced and natural earthquakes in the central and eastern U.S.
Get your flip-flops and shorts out because spring is arriving very early this year . . . at least 2-3 weeks early across almost the entire Southeast, from San Antonio to Atlanta to Washington, D.C. This unusually early spring is likely to keep rolling north, bringing relatively early ‘signs of spring’ to portions of the central Midwest and northeastern states.
