The Wood-Anderson torsion variant is used in defining a popular magnitude scale.Their placement in a borehole will reduce the noise recorded by them, which has been used to infer the locations of large storm centers. They record arrival times of S and P waves, whose difference is proportional to the distance to the epicenter. For 10 points, name these devices used to record earthquakes.
