Scientists research about earthquake, forecasting methods

Everyone in an earthquake-prone region wants to know when the next big earthquake might appear, shock, but are not well understood, and there are many methods that predicts the seismic risk. So what works best? A test of seven different techniques that could one day show, if there are earthquakes could help narrow the field.

So far, a reliable prediction of earthquakes is not represented, the short notice – there was no early warning in 2004, with the magnitude 6 Parkfield earthquake in California, for example, or scale mass 9 that Japan has shaken earlier this year, although it was one of the seismically monitored regions. However, earthquakes do not occur by chance, observed in space and time, the researchers said. To prefer large, when to the little ones, and earthquakes occur on active faults, semi-regular intervals over time.

Scientists have raised a number of different methods of earthquake prediction over the years. For example, a technical appearance extent and timing of small earthquakes to predict when more experience, another might provide geological evidence of ancient earthquake, if it could happen in the future to consider, but the estimation, it is questionable how much stress is built to guess the error, if they could break with the pressure.

Seven working groups submitted predictions. The objective was to assess the likelihood that earthquakes of magnitude would be 4.95 or more in over 7,600 networks in and around California’s experience includes about 360,000 square miles (930.000 km ²) between 2006 and 2011. During this time the earthquake that struck the area 31 quantities.
