- russdill 9y agoThe duration and intensity of an Earthquake are strongly correlated. You can even use it to estimate how strong a quake is and how far away you might be. The Sendai earthquake in 2011 was 6 minutes long. There's a story which I now cannot find about a seismic conference being held in Japan some distance from the epicenter. They felt only moderate shaking, but were immediately aware of the severity of the quake due to the duration.
