How can geologists tell where the epicenter of an earthquake is?
The epicenter refers to the point on the earth's surface above the focus of an earthquake. Geologists determine the epicenter with the use of 3 seismographs. This method is called triangulation.
What do you need to completely describe where an earthquake started?
Scientists use seismographs to measure thousands of earthquakes, large and small, every year. Some seismographs can detect ground movements as small as one hundred-millionth of a centimeter. The recording produced by a seismograph is called seismogram. By studying seismograms, scientist can determine the locations and strengths of earthquakes.
How do scientists measure the size of earthquakes?
They use seismographs and the richter scale to determine their size.
How can you determine if you live in an area where earthquakes are likely to occur?
You can determine if you live in a area were earthquakes are likely to occur by going on line and looking for past seismographs in your area.
What can help a geologist determine the earthquake risk for an area?
Geologists can determine the risk for an earthquake by measuring the seismic waves along faults as well as friction using a seismometer.
how do scientists determine earthquake location and how do they use this information?
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.
What uses information collected by seisomographs to determine the relative strength of an earthquake?
Richter Scale
Why do scientists need three seismographs?
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.

How do you know that earthquake is going to occur?
We can't yet tell the exact time a deadly earthquake will strike. We can make educated guesses based on an increase or decrease in seismic activity over time.

What information can scientists get by studying seismographs from different locations?
Each of a pair of seismic stations can determine the direction a seismic wave came from, and if that data is plotted on a map, the location where the lines cross will be the epicenter of the quake.
Why are seismographs stations needed to determine the location of an epicenter?
Three seismograph stations are needed to determine the location of an epicenter because each seismograph can determine distance to the epicenter but not direction. The point where the three circles intersect is the epicenter of the earthquake. +++ Focus - not epicentre, which is the point of maximum movement on the surface above the slip itself.
How do scientists measure the size of earthquakes?
They use seismographs and the richter scale to determine their size.
What kind of information would need to be collected about a planet in order to determine if humans could survive a visit to its surface?
All of the information.
What types of information can a scientist get by studying seismogram?
The location and movement of earthquake epicenters and faults. The internal structure and composition of the Earth The structure and layering of crustal rocks. The likely locations of mineral and hydrocarbon deposits. Information as to where it is wise and unwise to build structures. Where Tsunami are likely to happen Information as to when volcanoes may erupt. Where earthquake zones are the frequency of large earthquakes (if the seismic record is long enough)
How can you determine if you live in an area where earthquakes are likely to occur?
You can determine if you live in a area were earthquakes are likely to occur by going on line and looking for past seismographs in your area.
