WAYS TO DETECT AN EARTHQUAKE
1.using a seismograph
2.animal behavior
3.after a volcanic eruption occur in your place.
4.small cracks on a surface ground.
5.
It can detect that there is an earthquake nearby and it force also, this way it can help a lot of people to evacuate.
Yes, earthquake is the breakdown of geological structure. There is the pre-warning wave emitted out before the start of the earthquake. However, the detection can only give a warning at a short period of time.
A seismograph measures Earthquake.
Use a seismograph.
There are many probably earthquake precursors that could lead to useful predictions of when one will occur. Foreshocks are one way to predict when a quake is coming.

You can't.... but you can detect earthquakes while they occur. Currently, there are no devices that can detect an earthquake beforehand.
they check the intensity or magnitude of the earthquake.
p wave
You use a seismometer. Then, measure the magnitude according to the Richter scale.
There are a bunch of little earthquakes every minute. We don't even feel them! They don't cause any damage. The only way we know about these earthquakes is because seismographs (instruments used to detect seismic waves) detect the waves underground.
Scientists who study earthquakes are called seismologists. Of course, if an earthquake is at all large, it becomes rather easy to detect. You can feel the earth moving.
