Faster computers than those available in the 1960s were necessary and seismologists had to develop methods to process earthquake signals automatically.
Two fundamentally different but equally important types of scales are commonly used by seismologists to describe earthquakes.
These characteristics allow seismologists to determine the hypocentre of an earthquake using first-arrival methods.
Seismic waves are studied by geophysicists called seismologists.
It is regarded by seismologists as an aftershock of the 2010 earthquake.
Hough states that most seismologists do not believe this quake was "predicted" per se.
These unhappy seismologists will have to stay in distant parts of the world listening to their apparatus but, anyway, they will not be spies.
As a first step, two seismologists will shortly examine the area.
