| Going deep to learn the secrets of Japan's earthquakes|
NGDIR News Section-- The 11 March 2011 Tohoku-Oki earthquake was the largest and most destructive in the history of Japan. Scientists are hard at work trying to understand just what made it so devastating.
The 11 March 2011 Tohoku-Oki earthquake was the largest and most destructive in the history of Japan. Japanese researchers -- and their Norwegian partners -- are hard at work trying to understand just what made it so devastating.

| Geological Insights from Malaysia Airlines Flight MH370 Search|
NGDIR News Section--A rich trove of marine geophysical data acquired in the search for missing flight MH370 is yielding knowledge of ocean floor processes at a level of detail rare in the deep ocean.
The tragic disappearance of Malaysia Airlines flight MH370 on 8 March 2014 led to a deep-ocean search effort of unprecedented scale and detail. Between June 2014 and June 2016, geophysical survey teams aboard ships used echo sounding techniques to create state-of-the-art maps of the seafloor topo.....[More
| Ecuador anticipates $4 billion in mining investments by 2021|
NGDIR News Section-- Outcome is expected regardless of who wins upcoming presidential elections, says minister.
Ecuador is quickly gaining ground as a mining investment destination in Latin America thanks to a revised regulatory framework and a major investor engagement campaign that has already attracted around 420 applications for concessions in less than a year.
Getting to this point, however, has not been easy for a nation that has traditionally based its economy on oil, bananas, cacao.....[More
| NOAA Officials Stress Hurricane Danger and Storm Safety|
NGDIR News Section-- Agency scientists on a Hurricane Awareness Tour showcase NOAA research capabilities and warn that although winds can cause severe damage, the biggest killers are storm surges and inland flooding.
When Hurricane Charley approached southwestern Florida in 2004, hurricane specialist Rick Knabb thought a friend would evacuate his grandmother. To make sure she'd gotten out, Knabb, then a science and operations officer for the National Oceanic and Atmospheric Administration (NO.....[More
| Exploring the Mysterious Volcanoes of Arizona (Yes, That Arizona)|
NGDIR News Section-- Next week, I'll head off into the wilds of Arizona and Utah to visit some great geologic locales. Along with geoscience students from Denison University, I'll visit classics like the Grand Canyon and Zion-along with a place where only 1,000 years ago, some of the most recent volcanism in the lower 48 states occurred. It is a place where over 600 volcanic vents have been active over the past 6 million years. It is a place where lava flows dammed a river and sent molten rock u.....[More
| Taking Earth's inner temperature|
NGDIR News Section-- A new study suggests the mantle -- the mostly solid, rocky part of Earth's interior that lies between its super-heated core and its outer crustal layer -- may be hotter than previously believed. The new finding could change how scientists think about many issues in Earth science including how ocean basins form.
The temperature of Earth's interior affects everything from the movement of tectonic plates to the formation of the planet.
A new study led by Woods Hole Oceano.....[More
| Earth probably began with a solid shell|
NGDIR News Section-- Plate tectonics -- a defining feature of modern Earth and the driving force behind earthquakes, volcanoes and mid-ocean spreading ridges -- did not start until later in Earth's history, new research suggests. The work is the latest salvo in a long-standing geological debate: did plate tectonics start right away, or did Earth begin with a solid shell covering the entire planet? The new results suggest the latter.
Today's Earth is a dynamic planet with an outer layer compos.....[More
| Biochemical 'fossil' shows how life may have emerged without phosphate|
NGDIR News Section-- One major mystery about life's origin is how phosphate became an essential building block of genetic and metabolic machinery in cells, given its poor accessibility on early Earth. In a study published on March 9 in the journal Cell, researchers used systems biology approaches to tackle this long-standing conundrum, providing compelling, data-driven evidence that primitive life forms may not have relied on phosphate at all. Instead, a few simple, abundant molecules could have.....[More
| From rocks in Colorado, evidence of a 'chaotic solar system'|
NGDIR News Section-- Plumbing a 90 million-year-old layer cake of sedimentary rock in Colorado, a team of scientists from the University of Wisconsin-Madison and Northwestern University has found evidence confirming a critical theory of how the planets in our solar system behave in their orbits around the sun.
The finding, published Feb. 23, 2017 in the journal Nature, is important because it provides the first hard proof for what scientists call the "chaotic solar system," a theory proposed .....[More
| Defining Snow Drought and Why It Matters|
NGDIR News Section-- Swings from snow drought to extreme winter rainfall make managing reservoirs, like the Oroville Dam, incredibly difficult. But what exactly is "snow drought"?
On 12 February, water resource managers at the Oroville Dam issued an evacuation warning that forced some 180,000 Californians to relocate to higher ground. The story of how conditions got to this point involves several factors, but two clearly stand out: the need to prevent water shortages during a record drought, .....[More
