What else can I help you with?
What is the minimum number of seismic stations needed to determine the location of an earthquake and epicenter?
you need to have 3 seismic stations to triangulate the location of the earthquake and remember a earthquake can be from the inside of the earth but not necessarily at the epicenter because no epicenter is a straight line down.
What will happen if there were only two seismic stations recorded waves from an earthquake?
Then you would end up with 2 possible locations for the epicenter. You need a 3rd station to confirm the actual location.
Why are tsunamis measured?
you need to know what size was the wave that caused the destruction and for reasons of statistics. you have a wave size and you get an earthquake wich epicenter is in the sea, you know what size of wave to spect in the coast and the time to evaquate.
How many m3 nitrogen in 1 kilogram?
To answer this you need to find out the mass of 1m (or 1 dm) of nitrogen.
Why do you need latitude?
you need it to find where states and country's are
Can geologists use data from only two seismographs to locate an earthquake's epicenter?
No. Without a 3rd peice of data from another station, there will always be 2 different possible locations of the epicenter. You must have 3 seismographs to collect the data.
What do you need to collect to find the epicenter of an earthquake?
You need to find how many km the earthquake is
How many seismographs must be used to locate the epicenter of an earthquake?
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.
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 many seismographs needed to locate an earthquake?
A couple. You need to find where the tremors are coming from, basically which graph has the strongest reading even when you move it's location.
How many stations do you need to locate the epicenter of the earthquake?
To locate the epicenter of an earthquake, you typically need a minimum of three seismic stations. By triangulating the arrival times of the seismic waves at these stations, scientists can estimate the epicenter's location. More stations can increase the accuracy of the calculation.
Why do scientists need information from 3 cities to find the epicenter of an earthquake?
Scientists need information from at least three cities to determine the epicenter of an earthquake because each city provides a distance measurement to the epicenter. By triangulating these distances, scientists can pinpoint the intersection point, which represents the epicenter of the earthquake. Having data from three cities helps to confirm the location of the epicenter more accurately.
What do you need to pinpoint the epicenter of an earthquake?

How Many Stations Do You Need To Pinpoint the epicenter?
To pinpoint the epicenter of an earthquake, you typically need at least three seismic stations that record the arrival times of the seismic waves. By comparing the difference in arrival times between the stations, you can triangulate the epicenter using a process called seismic triangulation. Additional stations can provide more accurate results and help confirm the location.
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 many seismic do you need to find an earthquakes epicenter?
3. With 2 you can get possible locations (where the 2 circles intersect). With the 3rd reading, that circle will intersect the other two circles at one of those 2 candidate locations. See the link for a description.http://www.geo.mtu.edu/UPSeis/locating.html
Why do three circles show the epicenter of an earthquake?
Each circle is actually the radius around a reporting station. To find an earthquake's epicenter, you need at least three reporting stations. The radius around each station should meet at one point, the epicenter. This point should be about the size of a town, depending on how close or far the reporting stations are. With any less than three reporting stations, the exact point of the epicenter may not be located.
