now-defunct Kinect sensor used it. Archaeologists use it to discover ancient earthworks in Central America, and many robotics and autonomous vehicle companies use it to help vehicles “see.” The tech is everywhere, with dozens of startups using it in wildly different ways, from mapping malls to taking detailed measurements of people’s bodies for clothing. For the architecture and engineering industry, 3D scanning offers the ability to create a virtual corollary for any building, whether it’s Notre-Dame or an office complex in the suburbs. Kevin Dowling calls it a “digital twin.” Dowling is the founder of Kaarta, a 3D-scanning startup that is one of many competitors in this increasingly crowded industry. Though his background is in robotics (which is where the technology was developed, to help robots move around), these days two-thirds of Kaarta’s business is in mapping architecture, engineering, and construction. The company pitches its handheld … [Read more...] about The quest to digitally preserve the built world, from Notre-Dame to Easter Island
California is in an earthquake drought.It has been almost four years since the state experienced its last earthquake of magnitude 6 or stronger — in Napa. Southern California felt its last big quake on Easter Sunday 2010, and that shaker was actually centered across the border, causing the most damage in Mexicali.Experts know this calm period will eventually end, with destructive results. They just don’t know when this well-documented geological pattern will shift.“Earthquake rates are quite variable: We have a decade or two where we don’t have many earthquakes, and people expect that’s what California is always like,” said Elizabeth Cochran, seismologist with the U.S. Geological Survey. Eventually, “we’re going to dramatically see a change in earthquake rates.” Scientists have been warning California of seismic dangers, from the Big One on the San Andreas fault to other catastrophes that could come from lesser known faults, like … [Read more...] about California’s in an exceptional earthquake drought. When will it end?
By Lisa M. Krieger | [email protected] | Bay Area News GroupPUBLISHED: March 26, 2019 at 3:48 pm | UPDATED: March 27, 2019 at 4:48 am OAKLAND — In a major sign that California’s earthquake early warning system is moving forward, officials are testing the program in downtown Oakland on Wednesday morning. Like the familiar Amber Alert, starting at 11 a.m., the ShakeAlert will blare from smartphones in a 60-block area, announcing: “This is a test of the California Earthquake warning system. No action required. This is a test.” Then users will be asked to complete a survey that will reveal whether the exercise – the first public trIal in the Bay Area — was a success. Experts will measure how long it took for the message to reach people. In a real earthquake, the message would be different: Drop, cover and hold on. “We want to determine if a wireless emergency alert is a feasible solution,” said Ryan Arba of the state’s … [Read more...] about Oakland earthquake alert test: Is your phone listening?
Earthquakes kill roughly 20,000 people each year, on average. A new global mapping project shows which regions of the world are most at risk of earthquakes. 15 countries account for most of the death and destruction caused by quakes. Earthquakes kill, on average, about 20,000 people every year. When a quake strikes, there’s very little time to prepare, and survival has a lot to do with luck: Building codes, the time of day, and even the weather (which can trigger avalanches and mudslides) can play a role in how much destruction an earthquake causes. It has generally been tough to determine where in the world people are most at risk, since there was no standardised, comprehensive way to compare the consequences of shaking around the world. But now, a new mapping project led by the Global Earthquake Model Foundation (GEM) has done just that. “No one’s ever created a global earthquake risk map at this level of detail before, and certainly not for the public,” … [Read more...] about The 15 most earthquake-prone countries in the world, according to science
