Using Twitter to share information after a disaster
A new study shows how people used Twitter following the 2011 nuclear disaster in Japan, highlighting challenges for using the social media tool to share information; the study also indicates that social media have not changed what we communicate so much as how quickly we can disseminate it

Groundbreaking tests to offer better understanding of post-earthquake fires
Post-earthquake fires are a well-known and serious hazard, but very little is known about the performance of fire protection systems in earthquakes; groundbreaking tests to be conducted next week are aimed at better understanding of the effects of earthquakes on building systems designed to suppress or prevent the spread of fires

Seismic safety worries about South Carolina nuclear fuel facility
The worries about the seismic safety of nuclear energy-related facilities, worries which have only grown since the March 2011 Fukushima disaster, extend not only to nuclear power reactor, but to other facilities as well; the most recent example is a Westinghouse facility outside Columbia, South Carolina, one of only three facilities in the United States which make nuclear fuel for commercial reactors

Improve tsunami warnings by placing GPS on commercial ships
Researchers find that commercial ships travel across most of the globe and could provide better warnings for potentially deadly tsunamis; this finding came as a surprise because tsunamis have such small amplitudes in the deep water, in contrast to their size when they reach the coastline, that it seemed unlikely that the tsunami would be detected using GPS unless the ship was very close to the source and the tsunami was very big

New micro helicopters for search and rescue missions
New micro helicopters have a diameter of about fifty centimeters, weigh only 1,500 grams; they do not rquire GPS or remote control to navigate; they are designed to maneuver in tight or even enclosed spaces, and to detect and fly around any obstacle; possible uses could include protection or rescue missions, and they are ideal for flying over disaster areas and giving a picture of the situation from the air or locating victims

Safe fracking requires distance from sensitive rock strata
Fracking — the process which releases natural gas and oil from shale rock strata – is becoming more and more popular because it promises access to new, abundant sources of energy; the process of fracking, however, has been associated with increase in the frequency of earthquakes and contamination of drinking water; scientists examine thousands of fracking operations in the United States, Europe, and Africa, and conclude that in order to minimize water contamination and earthquakes, there should be a minimum distance of at least 0.6 km between a fracking operation and sensitive rock strata

Increased U.S earthquakes may be caused by fracking
From 1970 to 2000 the number of magnitude 3.0 or greater temblors in the U.S. mid-continent averaged twenty-one annually; by 2011 the number of such quakes had increased to 134; a new study by the U.S. Geological Survey links the increase of seismic activity to the increase in the use of hydraulic fracturing, or fracking

Using Drone Swarms to Fight Forest Fires
Forest fires are becoming increasingly catastrophic across the world, accelerated by climate change. Researchers are using multiple swarms of drones to tackle natural disasters like forest fires.
How Climate Change Will Affect Conflict and U.S. Military Operations
“People talk about climate change as a threat multiplier,” said Karen Sudkamp, an associate director of the Infrastructure, Immigration, and Security Operations Program within the RAND Homeland Security Research Division. “But at what point do we need to start talking about the threat multiplier actually becoming a significant threat all its own?”
