Solar super-storms “inevitable”: Scientists
Solar storms are caused by violent eruptions on the surface of the Sun and are accompanied by coronal mass ejections (CME). The largest ever solar super-storm on record occurred in 1859 and is known as the Carrington Event: This massive CME released about 1,022 kJ of energy — the equivalent to ten billion Hiroshima bombs exploding at the same time — and hurled around a trillion kilograms of charged particles towards the Earth at speeds of up to 3,000 km/s. These types of events are not just a threat, but inevitable. NASA scientists have predicted that the Earth is in the path of a Carrington-level event every 150 years on average — which means that we are currently five years overdue — and that the likelihood of one occurring in the next decade is as high as 12 percent.

Cold-formed steel construction withstands seismic challenges better than expected
Engineering researchers have provided the building blocks necessary for enabling performance-based design for cold-formed steel buildings, structures that have shown in shake-test experiments at the State University of New York at Buffalo to withstand seismic loading much better than previously expected. Light, strong, and easy to construct cold-formed steel (CFS) buildings are repetitively framed with light steel members and conform to well-defined seismic design codes. Until this latest research, however, engineers and builders significantly underestimated the seismic strength of cold-formed steel structures.

Electromagnetic disaster could cost trillions and affect millions. We need to be prepared
In 1962, a high-altitude Pacific nuclear test caused electrical damage 1,400 km away in Hawaii. A powerful electromagnetic pulse (EMP) – created either by a solar storm or a high-altitude nuclear explosion — poses a threat to regions dependent on electricity, as such pulses could cause outages lasting from two weeks to two years. The main problem is the availability of spare transformers. Superstorm Sandy’s worst effects were in a single location. In the case of a big EMP surge, replacement transformers would be needed in hundreds of locations at the same time. The cost of an EMP pulse to the U.S. economy would likely be in the range of $500 million to $2.6 trillion. A report by the U.S. National Academies was even more pessimistic, guessing at a higher range and a multi-year recovery. Besides disrupting electricity such storms can also destroy satellites, disrupt GPS navigation, and make other parts of the infrastructure fail.

Home Depot faces lawsuit over Joplin, Missouri tornado deaths
Home Depot is being sued in a wrongful death lawsuit by a woman who lost her husband and two children during a 2011 tornado in Joplin, Missouri. Edie Housel is contending that Home Depot is responsible for the death of her family due to the improper construction of the Home Depot store in which the three — along with five other people — were killed.

Erosion research could guide new preservation techniques
Visitors to the Western Wall in Jerusalem can see that some of its stones are extremely eroded. This is good news for people placing prayer notes in the wall’s cracks and crevices, but presents a problem for engineers concerned about the structure’s stability. Research could guide development of new preservation techniques for weakened structures.

Texas coastal areas still unprepared for disaster
When Hurricane Ike struck Galveston, Texas in 2008, leaving billions of dollars in damages and at least 100 people dead, residents knew that they were underprepared. Experts say that Texas coastal residents still are. Unlike Louisiana and New York after Hurricanes Katrina and Sandy, Texas has not developed a plan to protect its coast, and the state has failed to seek the same level of federal funding after Ike as the two other states sought after their hurricanes.

Rockefeller Foundation, USAID launch new Global Resilience Partnership
The new initiative, funded with $100 million from the Rockefeller Foundation, aims to institute a new model for solving the interrelated challenges of the twenty-first century such as persistent and often extreme poverty, food insecurity, and climate shocks. By better aligning humanitarian and development planning, connecting the private sector with civil society and government, and crowdsourcing innovations and solutions, the Resilience Partnership will enable communities to prepare for, withstand, and emerge stronger from shocks and stresses in a way that reduces chronic vulnerability and keeps them on the pathway to development.

Tornado strength, frequency linked to climate change
New research shows that climate change may be playing a key role in the strength and frequency of tornadoes hitting the United States. Though tornadoes are forming fewer days per year, they are forming at a greater density and strength than ever before. “We may be less threatened by tornadoes on a day-to-day basis, but when they do come, they come like there’s no tomorrow,” one of the researchers said.

N.C. science panel begins updating sea level rise report
North Carolina officials announced last week that the state-appointed science panel supported by the Coastal Resources Commission(CRC) has begun updating a controversial 2010 sea-level rise report. The CRC oversees development in North Carolina’s twenty coastal counties. In May, the CRC votedto narrow the scope of the pending report to reflect the effects of sea-level rise for the next thirty-years, as opposed to the original timeframe of 100 years in the 2010 report. “I think the concept of doing it for 30 years will add credibility to the study,” Frank Gorham, the CRC’s chairman, said last Thursday. “People can think in 30-year timeframes.”

Complicating the task of quantifying earthquake hazards in the Pacific Northwest
Nearly forgotten research from decades ago complicates the task of quantifying earthquake hazards in the Pacific Northwest, according to a new report from scientists at the U.S. Geological Survey, the University of Washington, and other universities. The report focuses on the Cascadia subduction zone — a giant active fault that slants eastward beneath the Pacific coast of southern British Columbia, Washington, Oregon, and northern California.

Assessing flood risk in a changing climate
Growing consensus on climate and land use change means that it is reasonable to assume, at the very least, that flood levels in a region may change. In an argument grounded in an analysis of the inherent limitations of statistical analyses, the authors of a new study suggest that researchers’ typical starting assumption that flood behavior is not changing — even in the face of suspected trends in extreme events and knowledge of how difficult such trends are to detect — causes water managers to undervalue flood protection benefits, opening the door to unnecessary losses down the line.

Tech firm creates software pairing response systems with open data
A new application, called Disaster Assessment and Assistance Dashboard (DAAD), harnesses emergency response data in real-time and across multiple departments and agencies. DAAD will function as a central hub for information in the event of a disaster — using more than 100 different interfaces that upload data. Additionally, the hub will work in accordance with all manner of local government organizations such as fire stations, police stations and hospitals to further create a larger picture during the actual moments of an emergency.

Kansas, Missouri invest in tornado safe-rooms
Last year’s tornado season prompted officials in Kansas and Missouri to invest heavily in safe rooms to shelter residents from future severe weather events. Schools tend to be popular choices for safe rooms, but new funding from FEMA is helping cities build safe rooms in other public spaces. The safe rooms are built to withstand tornado winds of up to 250 mph, and can survive being hit by a 67 mph projectile vertically or 100 mph horizontally.

New Bay Area hospital is constructed to withstand the most severe earthquake
The new Stanford Hospital is being constructed to withstand the most severe tremors. The new hospital will be placed on 206 base isolators, enormous parallel steel plates with a sort of ball bearing suspension system between them, providing a buffer between the building and the moving ground. Each plate can move as much as three feet in any direction, allowing the building to shift up to six feet during seismic activity. Reducing horizontal movement during an earthquake minimizes the strain on a building’s vertical load-bearing structures. When completed, in 2017, the building will be one of the most seismically safe hospitals in the country, able to continue operations after an 8.0, or “great,” earthquake.
