Fracking in Ohio: tapping a valuable resource or invading the environment?
A new study is examining methane and other components in groundwater wells, in advance of drilling for shale gas which is expected over the next several years in an Ohio region. A team of researchers spent a year doing periodic testing of groundwater wells in Carroll County, Ohio, a section of Ohio that sits along the shale-rich Pennsylvania-West Virginia borders. The study analyzed twenty-five groundwater wells at varying distances from proposed fracking sites in the rural, Appalachian, Utica Shale region of Carroll County.

Fracking does not cause quakes, but disposing water used in the process might: scientists
Researchers say that human activity associated with oil and gas production may sometimes cause earthquakes, but the problem lies in the disposal of drilling fluids in the underground injection wells, not hydraulic fracturing. The vast majority of injection wells do not cause quakes.

Los Alamos National Lab describes storm damage to affected New Mexico areas
Hours after a disaster declaration by Los Alamos County, Los Alamos National Laboratory officials on Friday described “millions” of dollars in damage to environmental monitoring stations, monitoring wells, access roads, and badly eroded canyon bottoms. “Last week we experienced an epic event,” said Dave McInroy, the laboratory’s program director for environmental corrective actions.

Deep earthquakes simulated in the laboratory
More than twenty years ago, researchers discovered a high-pressure failure mechanism that they proposed then was the long-sought mechanism of very deep earthquakes (earthquakes occurring at more than 400 km depth). The result was controversial because seismologists could not find a seismic signal in the Earth that could confirm the results. Seismologists have now found the critical evidence. Indeed, beneath Japan, they have even imaged the tell-tale evidence and showed that it coincides with the locations of deep earthquakes.

California mulls costly earthquake early-warning system
The price of an early warning system which would alert California officials about an earthquake within sixty seconds before a major temblor strikes would be $80 million. The California legislature passed a bill on 13 September, requiring the state to develop the earthquake warning system, but it is unclear whether Governor Jerry Brown will sign the bill.

NASA, DHS to demonstrate disaster rescue tool
NASA and DHS are collaborating on a new radar device which detects heartbeats of victims trapped in wreckage. The device, known as the Finding Individuals for Disaster and Emergency Response (FINDER), can locate individuals buried under as much as thirty feet of crushed materials, hidden behind twenty feet of solid concrete, or from a distance of 100 feet in open spaces.

Flood insurance is not available to Canadian homeowners – should it be?
Canada is the only G8 country in which insurance against overland flooding is not available to homeowners — but does it have to remain that way? A study released Monday explores issues related to flooding and property insurance, aiming to advance informed discussion of the potential better to protect Canadian homeowners. It reveals that while insurance executives are concerned about the lack of flood insurance and agree on many of the associated issues, opinions remain mixed concerning its viability in Canada.

More equitable access to DNA identification after disaster or conflict needed: experts
The April 2013 collapse of the Rana Plaza Factory Building in Bangladesh, in which more than 1,130 people were killed, is only the latest in a long line of events that has made plain the plight of the families whose loved ones go missing after conflict and disaster. Experts argue that international structures are needed to promote more equal access to forensic identification technologies, ensure their fair and efficient use, and provide uniform protections to participants following large-scale conflict and disaster.

Calculating the cost of a ton of mountaintop removal coal
To meet current U.S. coal demand through surface mining, an area of the Central Appalachians the size of Washington, D.C., would need to be mined every eighty-one days. This is about sixty-eight square miles — or roughly an area equal to ten city blocks mined every hour. A 1-year supply of coal would require converting about 310 square miles of the region’s mountains into surface mines.

Studying tsunami resilience in California
While scientists cannot predict when a great earthquake producing a pan-Pacific tsunami will occur, thanks to new tools being developed by federal and state officials, scientists can now offer more accurate insight into the likely impacts when tsunamis occur. This knowledge can lead officials and the public to reduce the risk of the future tsunamis that will impact California.

New model corrects tornado records
In the wake of deadly tornadoes in Oklahoma this past spring, researchers have developed a new statistical model that will help determine whether the risk of tornadoes is increasing and whether they are getting stronger. Climatologists have been hampered in determining actual risks by what they call a population bias: That is, the fact that tornadoes have traditionally been underreported in rural areas compared to cities, but now researchers have outlined a method that takes the population bias into account, as well as what appears to be a recent surge in the number of reported tornadoes, thanks in part to an increasing number of storm chasers and recreational risk-takers roaming Tornado Alley.

Cold-formed steel rebuilds earthquake-resistant architecture
When engineers attempt to make a building earthquake-resistant, they use specific structural components, appropriately called details, to absorb earthquake forces and help direct some of those forces back to the ground. That works, but when an earthquake hits, the entire building reacts, not just the sections containing details. Even though academic research has led to improvements to the original building codes over the decades, there is much to be learned about the entire system of a cold-formed steel building as it responds to an earthquake.

New technique developed to assess the cost of major flood damage
A new approach to calculating the cost of damage caused by flooding was presented at the International Conference of Flood Resilience: Experiences in Asia and Europe which was held last week. The methodology combines information on land use with data on the vulnerability of the area to calculate the cost of both past and future flooding events.

“Climate Change, Water Conflicts, and Human Security” report released
Increasingly, climate change and the associated increase in the frequency of extreme weather events such as floods, droughts, and rising sea level, are acknowledged as not only having humanitarian impacts, but also creating national and regional political and security risks. While people and governments can adapt to these impacts, their capacity to do so varies.

Global warming increasing risk of record heat: scientists
Drought shriveled crops in the Midwest, massive wildfires raged in the West, and East Coast cities sweltered. The summer of 2012 was a season of epic proportions, especially July, the hottest month in the history of U.S. weather record keeping. As the world warms, it is likely that we will continue to see such calamitous weather. Scientists caution against trying to determine whether global warming caused any individual extreme event, but they say that the observed global warming clearly appears to have affected the likelihood of record heat.

Huge Areas May Face Possibly Fatal Heat Waves if Warming Continues
A new assessment warns that if Earth’s average temperature reaches 2 degrees C over the preindustrial average, widespread areas may become too hot during extreme heat events for many people to survive without artificial cooling.
Trump’s Cuts to Federal Wildfire Crews Could Have “Scary” Consequences
President Donald Trump’s moves to slash the federal workforce have gutted the ranks of wildland firefighters and support personnel, fire professionals warn, leaving communities to face deadly consequences when big blazes arrive this summer. States, tribes and fire chiefs are preparing for a fire season with minimal federal support.
