text: The surface-wave magnitude scale also had no distance restrictions between the earthquake epicentre and the location of the seismograph, and the body-wave magnitude scale, with its approximately 1,000-km (620-mile) range, was viewed as accurate enough to measure the few relatively small earthquakes that occurred in eastern North America.
