There appears to be strong seismic signals around 09:38:52 at station MVL (Millersville, Pa; ∆= 139 km), but the signals are too high frequency (5-10 Hz) and too high amplitude (328 nm/s at 139 km). Hence, it appears be noise perhaps due to electrical disturbance ...

Seismometer

Seismometers are instruments that measure motion of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources.The word derives from the Greek σεισμός, seismós, a shaking or quake, from the verb σείω, seíō, to shake; and μέτρον, métron, measure and was coined by David Milne-Home in 1841, to describe an instrument designed by Scottish physicist James David Forbes.Seismograph is another Greek term from seismós and γράφω, gráphō, to draw. It is often used to mean seismometer, though it is more applicable to the older instruments in which the measuring and recording of ground motion were combined than to modern systems, in which these functions are separated.Both types provide a continuous record of ground motion; this distinguishes them from seismoscopes, which merely indicate that motion has occurred, perhaps with some simple measure of how large it was.The concerning technical discipline is called seismometry, a branch of seismology.
