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.
seismographs
Scientists use seismographs to monitor earthquakes. Though, a seismograph merely registers an earthquake. By using at least three seismograph stations, and using triangulation, the epicentre of the earthquake is able to be plotted.
Having three seismographs allows scientists to triangulate the epicenter of an earthquake more accurately by measuring the time difference in the arrival of seismic waves at each station. This helps determine the location and magnitude of the earthquake more precisely for effective response and mitigation efforts. Additionally, having multiple seismographs provides redundancy in data collection in case one station fails or malfunctions.
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.
Not just by looking at it. Scientists do detailed analysis using seismographs, and chemical samples of gas and,where possible, lava. These can point to whether or not a volcano is getting read to erupt.
Scientists use seismographs.
Scientists developed seismographs in the late 19th century. The first seismograph was invented by John Milne in 1880.
The three types of the Seismographs are: - magnitude,shaking and focus.

You would need at least three different seismometer locations to triangulate an earthquake's location.

three
At least three seismographs are needed to locate the epicenter of an earthquake. By comparing the arrival times of seismic waves at different stations, scientists can triangulate the epicenter. With three or more points of arrival time data, they can pinpoint the exact location of the earthquake epicenter.
