Can residents get a seismograph at their house?
Not as a rule. Seismographs will be used to measure vibrations from blasting to make sure they remain within specified limits. Seismographs will be placed at locations close to the blast in order to provide measurements that indicate the severity of the blast and which allow for adjustments to be made in future blasts if necessary. The results obtained from the seismographs may be used to estimate the severity of the vibrations at locations further away.
