| Backpackers demonstrated resounding leadership in aftermath of Nepal earthquake|
NGDIR News Section-- A first-of-its-kind study exploring the experiences of tourists exposed to a natural disaster immediately in its aftermath reveals four dominant themes: emotional turmoil, quick recovery, springing into action, and connection to the army.
Prof. Haya Itzhaky was enjoying a routine day in Nepal on April 25, 2015. She had been in the region for about three months studying the behavior of post-Israel Defense Forces (IDF) Israeli backpackers when tragedy struck: a powerful ear.....[More
| Release of water shakes Pacific plate at depth|
NGDIR News Section-- A team of seismologists analyzing the data from 671 earthquakes that occurred between 30 and 280 miles beneath the Earth's surface in the Pacific Plate as it descended into the Tonga Trench were surprised to find a zone of intense earthquake activity in the downgoing slab. The pattern of the activity along the slab provided strong evidence that the earthquakes are sparked by the release of water at depth.
Tonga is a seismologists' paradise, and not just because of the whi.....[More
| At least 4 dead amid major flooding and mudslides as biggest storm in years barrels into L.A. area|
NGDIR News Section-- Cleanup was beginning across Southern California on Saturday after a storm that forecasters billed as the most powerful in years caused flooding on multiple freeways, triggered dramatic mudslides and downed hundreds of trees and power lines.
The storm was moving out Saturday morning after dumping record rain in some areas and leaving havoc in its wake.
Thousands of Los Angeles County residents remained without power early Saturday, while road crews scrambled to repair .....[More
| 188,000 evacuated as California's massive Oroville Dam threatens catastrophic floods|
NGDIR News Section-- About 188,000 residents near Oroville, Calif., were ordered to evacuate Sunday after a hole in an emergency spillway in the Oroville Dam threatened to flood the surrounding area. Thousands clogged highways leading out of the area headed south, north and west, and arteries major and minor remained jammed as midnight approached on the West Coast- though by early Monday, Lake Oroville's water level had dropped to a point at which water was no longer spilling over, and the crisi.....[More
| More Frequent Glacial Quakes on Greenland Signal Ice Retreat|
NGDIR News Section-- Between 1993 and 2011, the annual number of earthquakes caused by gigantic blocks of ice breaking away from Greenland's glaciers has increased, further evidence of accelerating ice loss.
As the Greenland ice sheet creaks and cracks, scientists are listening.
Since the 1990s, researchers have seen a rise in the number of glacial earthquakes emanating from Greenland's glaciers-earthquakes that stem from massive blocks of ice calving from glacier fronts. Nearly half of th.....[More
NGDIR News Section-- Also known as golden beryl or yellow beryl. Inappropriately as yellow emerald.
What is Heliodor?
Heliodor is a name used by mineralogists and gemologists for specimens of the mineral beryl with a yellow, greenish yellow, or golden-yellow color. Pure beryl is colorless, but impurities within the mineral cause beryl to occur in a variety of different colors. The yellowish colors of heliodor are usually caused by small amounts of iron within the mineral's crystal structure......[More
| Pinpointing the Trigger Behind Yellowstone's Last Supereruption|
NGDIR News Section-- Geologists suggest that mixing of magma melt pockets could have caused the explosion a little more than 600,000 years ago.
Yellowstone National Park is renowned for more than just its hot springs and Old Faithful. The area is famous in the volcanology community for being the site of three explosive supereruptions, the last of which was 631,000 years ago.
During that eruption, approximately 1000 cubic kilometers of rock, dust, and volcanic ash blasted into the sky. Debr.....[More
| Ocean Acidification: High-tech mooring will measure beneath Antarctic ice|
NGDIR News Section-- Scientists have deployed a high-tech mooring beneath the seasonally ice-covered waters around Antarctica to better understand ocean acidification in polar regions.
Earth's oceans have soaked up about a third of the carbon dioxide added to the atmosphere by humans through use of fossil fuels and other activities. That's good news for those concerned with greenhouse warming, but bad news for the marine life that's sensitive to the increasing acidity extra CO2 brings to ocea.....[More
| Global warming hiatus disproved -- again|
NGDIR News Section-- Scientists calculated average ocean temperatures from 1999 to 2015, separately using ocean buoys and satellite data, and confirmed the uninterrupted warming trend reported by NOAA in 2015, based on that organization's recalibration of sea surface temperature recordings from ships and buoys. The new results show that there was no global warming hiatus between 1998 and 2012.
A controversial paper published two years ago that concluded there was no detectable slowdown in oce.....[More
| The crack in this Antarctic ice shelf just grew by 11 miles- A dramatic break could be imminent|
NGDIR News Section-- An enormous rift in one of Antarctica's largest ice shelves grew dramatically over the past month, and a chunk nearly the size of Delaware could break away as soon as later this winter, British scientists reported this week.
If this happens, it could accelerate a further breakup of the ice shelf, essentially removing a massive cork of ice that keeps some of Antarctica's glaciers from flowing into the ocean. The long term result, scientists project, could be to noticeably .....[More
