They suggest that it is horrible and you have to run away from it.
The scientists determined the size of the earthquake by combining forces when the tsunami triggered them>

Seismologist
Scientists use seismic waves to find an earthquake epicenter. By analyzing the arrival times of primary (P) and secondary (S) seismic waves at different seismic stations, scientists can triangulate the epicenter of the earthquake.
they do it by using a seismograph
It takes three seismographs to locate an earthquake. Scientists use a method called triangulation to determine exactly where the earthquake occurred. If a circle is drawn on a map around three different seismographs where the radius of each is the distance from that station to the earthquake, the intersection of those three circles is the epicenter.
a ricter scale
They use the Richter Scale.
No there has not "yet" been an earthquake in the Rocky Mountains. Although scientists believe that there will be an upcoming earthquake near the Rocky Mountains.
Scientists use instruments called seismometers to detect and record seismic waves emitted by earthquakes. By analyzing the timing and intensity of these waves at different monitoring stations, scientists can triangulate the epicenter of the earthquake and determine its exact location.
Scientists use devices called Seismographs to determine the epicenter of an earthquake. If 3 or more seismographs detect an earthquake, seismic wave activity can be measured and quantified and then cross-referenced with other data (the primary and secondary seismic waves) to determine the earthquake's location.
