seismologists
They study tremors
Seismologists are scientists who study earthquakes and the propagation of seismic waves through the earth.
They analyze data from seismographs to determine earthquake locations, magnitudes, and fault mechanics.
Seismologists warned that the fault was overdue for a major rupture.
The field also encompasses using seismic waves to map the earth's interior structure.
