Scientists: should turn smart phones into seismic sensors

NetEase Science and technology news September 30, according to Science and technology blog Theverge reported that over the years, scientists have been trying to collect accurate real-time seismic data, but a bulletin from the American Seismological Society said that has found a better tool to complete the work, the smart phone into a seismic sensor. The paper finds that the current smartphone accelerometer sensitivity is sufficient to detect earthquakes of magnitude 5 or higher intensity. Because smartphones are used widely, scientists speculate that future smartphones could be used to create "urban seismic networks" to transmit real-time geological data. The authors say the article was inspired by the Stanford University's Quake-catcher Network, which uses volunteers ' computers to create a seismic data network. However, using a smartphone accelerometer is cheaper and easier to carry in an extreme environment. But the authors say the accelerometer sensors of smartphones need to be more sensitive to use in earthquake sites. But once technically achieved, it could become the perfect seismic research tool. As one researcher said, "From the outset, this technology seems to meet all the requirements for monitoring earthquakes, especially in extreme environments like volcanic eruptions." "(John)
