Scientists at the Columbia University have discovered a totally new way to study earthquakes. They picked out different types of earthquakes from three years using machine learning algorithms. According to them, these machine learning methods pick out very subtle differences in the raw data that we're just learning to interpret. Scientists particularly identified earthquake recordings at The Geysers in California, one of the world's oldest and largest geothermal fields. They assembled a catalog of 46,000 earthquake recordings, each represented as energy waves in a seismogram. They then mapped changes in the waves' frequency through time, which they plotted as a spectrogram--a kind of musical roadmap of the waves' changing pitches, were they to be converted to sound.

In a new study in Science Advances, researchers at Columbia University show that machine learning algorithms could pick out different types of earthquakes from three years of earthquake recordings at The Geysers in California, one of the world's oldest and largest geothermal reservoirs. The repeating patterns of earthquakes appear to match the seasonal rise and fall of water-injection flows into the hot rocks below, suggesting a link to the mechanical processes that cause rocks to slip or crack, triggering an earthquake. "It's a totally new way of studying earthquakes," said study coauthor Benjamin Holtzman, a geophysicist at Columbia's Lamont-Doherty Earth Observatory. "These machine learning methods pick out very subtle differences in the raw data that we're just learning to interpret." The approach is novel in several ways.

LAS VEGAS, NV - JANUARY 05: Volkswagen's I.D., an autonomous self-driving concept vehicle is displayed at the Volkswagen booth at CES 2017 at the Las Vegas Convention Center on January 5, 2017 in Las Vegas, Nevada. CES, the world's largest annual consumer technology trade show, runs through January 8 and features 3,800 exhibitors showing off their latest products and services to more than 165,000 attendees. The Consumer Electronics Show (CES) has officially kicked off today in Las Vegas and it's just as you expected. Lots of news around smart showers, mirrors and even pillows. Probably the last thing you would expect to hear coming out of the world's largest consumer electronics show in LasVegas is from AARP, the consumer advocacy group for Americans over 50.
