It could be that we are always better detection. It could be a freak anomaly. It could be something else. What we do know is that more earthquakes more energy on the Richter scale it will make a big damage for the environment. Remember that the earthquakes are on a logarithmic scale. An earthquake of 5.0 is ten times higher than 4.0. And a 6.0 is a powerful 100x more 4.0.
