Researchers at the University of British Columbia (Okanagan campus) examined a variety of bridge types along with design requirements under the Canadian Highway Bridge Design Code. As part of the research, the seismic performance of shape memory alloy reinforced and post-tensioned bridge piers have been tested in the University’s Applied Laboratory for Advanced Materials and Structures (ALAMS). The results, published in the Journal of Structural Engineering, ASCE, point out that bridges are being built to withstand the force of an earthquake, however they are being overbuilt, resulting to unnecessary construction expenses.

A serious 6.2 R earthquake hit central Italia on Wednesday morning. Amatrice, Pescara del Tronto and Arquata del Tronto were subjected to the deady earthquake and have been severely damaged. 247 people were killed and 400 are injured. Among them many are children.

On Tuesday a magnitude-7.3 earthquake shook the impoverished country of Nepal, this is the second earthquake to hit the impoverished country in less than a month. On Wednesday, officials with bullhorns walked through the badly damaged streets of Chautara, a small town northeast of Kathmandu, calling for people to leave buildings in danger of collapsing.

An earthquake-detection system developed by the University of California Berkeley’s Seismological Laboratory performed well during the recent earthquake that struck the Napa Valley region on August 24. The system was able to produce a warning message 10 seconds before the magnitude-6 temblor struck. "It was definitely a great proof-positive that the system works just like we'd hoped," says Jennifer Strauss, the lab's external relations officer. "One of the things the Napa quake did show us is you need to make sure there are enough sensors," says Strauss. One member of the lab even stated the warning could have gone out 2.5 seconds earlier had the lab received more funding to install more sensors in the area. California unanimously passed a bill last year that would create a state-wide early detection system. Funding for such project, however, has yet to be found.

A magnitude 6.0 earthquake struck the Napa Valley region on Sunday and injured at least 172 people. The earthquake left many cracked roads, damaged buildings, and broken wine bottles. The earthquake was the largest to hit the California Bay Area since the 1989 Loma Prieta earthquake. Safety inspectors have been working around the clock to check on the health of the area’s infrastructure.

The 2011 earthquake and tsunami that hit Japan left a devastating path of destruction and claimed the lives of 19,000 people.  Most of the hardest hit areas by the disaster including Fukushima, Miyagi and Iwate were completely washed away. The Japanese government would now like to build 230 miles of walls along the coastline in these three prefectures. The project to tsunami-proof these stretches of land will cost $8.6 billion and take nearly 25 years to finance with taxpayer money.  While the government seems determined to build what is being dubbed “The Great Wall of Japan”, many of the 2011 disaster survivors feel that the walls are a waste of money and do not want to see Japan turn into a concrete fortress.

A decade after the identification of potentially vulnerable concrete school buildings across the state of California, a new report published by UC Berkeley based Pacific Earthquake Engineering Research Center (PEER) brings attention back to the older concrete LA buildings. The list contains 1,454 buildings, including schools, offices, theaters, churches and many residential buildings.
