According to Rong-Gong Lin II, Raoul Rañoa and Jon Schleuss of the LA Times, the city of Santa Monica is considering a mandated seismic retrofit program: Santa Monica’s safety rules would go beyond what Los Angeles has done by requiring not only wood-frame apartments and concrete buildings to be retrofitted, but also steel-frame structures. The ordinance … Continue reading Santa Monica latest city to mandate seismic retrofits for older buildings
Researchers at Stanford are pleased to report the following: Thousands of miles of buried optical fibers crisscross California’s San Francisco Bay Area delivering high-speed internet and HD video to homes and businesses. Biondo Biondi, a professor of geophysics at Stanford’s School of Earth, Energy & Environmental Sciences, dreams of turning that dense network into an … Continue reading Stanford researchers working on regional “seismic observatory” using existing fiber optic networks
Concrete is a really amazing building product that provides strength and protection, particularly when reinforced with steel, or when combined with various admixtures. Unfortunately, concrete is extremely costly to produce in terms of its environmental impact. By some accounts, concrete production results in the release of a ton of carbon, for every ton of concrete. … Continue reading New concrete product claims to be more earthquake resistant AND more sustainable
Admittedly, this is a little strange, but clearly could be a practical measure in certain parts of the world. Dahir Insaat Corporation is a Turkish company that specializes in pre-fab cast-in-place construction buildings ranging in size from a small cottage to an entire apartment block. The company also has developed a design concept for an … Continue reading “Earthquake Safety Bed” protects occupants from building collapse
Earthquakes are a serious design consideration when it comes to the built environment. Particularly in areas along the Pacific Rim, where seismic activity is somewhat regular. CNN reports on an innovative, and certainly very aesthetically striking design concept in Japan that is intended to help a building not so much “fight” earthquakes, but will rather … Continue reading External braided carbon fiber rods designed for dampening impact of earthquakes
During the tail end of my junior year of high school, my family and I temporarily relocated to Southwest Missouri. We were fleeing the cratering of the entire construction industry in Southern California, hoping to catch the extraordinary boom in construction taking place surrounding Branson. Although the school year only had a few weeks left, … Continue reading Why is the risk for earthquakes just as high in parts of the Midwest as it is in California?
During an earthquake, as most people may recall from grade school, sometimes a strange phenomenon occurs in sandy soils known as liquefaction. And it is exactly what it sounds like — the ground that is made up of solid particles (sand) suddenly behaves like a liquid.
Researchers have for years warned the public, various government agencies and building owners/managers of the potential dangers related to older buildings within reach of Southern California’s notorious faults in a major earthquake. In short, what building experts once thought would be sufficient, in terms of structural design requirements, we now know could leave building occupants … Continue reading Santa Monica’s mandatory seismic retrofit program to begin in earnest
In April of 2009, an earthquake caused extensive damage to the ancient city of L’Aquila, Italy. Relatives of people I know in that region luckily survived without injury. However, the Italian government surprised the International scientific community when it filed criminal charges against the geologists for “failing to predict the earthquake.”
Fortunately, the geologists were acquitted in October. Appeals by prosecutors are still expected, so this story is not yet over. Continue reading “Italian scientists facing prison for failing to predict 2009 earthquake acquitted, for now…”
