The earthquake will come no matter what a person does, taking us back to how dangerous nature can really be. 8. The most important seismological tool would be the seismograph machine. “Scientists use the seismogram recordings made on the seismograph at the surface of the earth to determine how large the earthquake was” (Wald, 2009).
