Scientists have been planting seismographs along fault lines for decades. These tell the scientist what area has activity first. With these machines they can pin down activity within 50 feet most of the time.

5 How do scientists know the exact spot where an earthquake begins?

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.


Is it false that scientist know that exact rate of evoltion?

yes


How did the distance of the epicenter of Chile's earthquake the local geology and the construction affect of the earthquake?

because the buildings fall and the scientist have to learn how to make better ones so in the future they know what building is better

Why is it important to know how long earthquakes last for?

It is important to known how long an earthquake will last so that scientist will know if there will be a bigger one. The bigger earthquakes are called main-shock.


What if scientist could take a few human cells and make an exact copy of you or anyone else?

i dont know maybe make more of you


How a seismograph is used?

A seismograph is located under the ground. When there is an earthquake, the ground shakes, which also shakes the pen on the seismograph, making it move along the paper, drawing lines. To know how strong the earthquake was, scientist can look on the paper. The bigger the lines, the stronger the earthquake was.


Will there be a big earthquake in LA any time soon?

California sits an a variety of fault lines and it is only a matter of when, not if, a big earthquake will occur. Scientists say it's a certainty. They just don't know the exact time it will happen.


Do scientists know when an earthquake can happen?

Scientists can predict where earthquakes are more likely to occur based on historical data and tectonic plate movements, but the exact timing of an earthquake is difficult to predict accurately. Monitoring of seismic activity can provide some warning signs, but forecasting the precise time of an earthquake remains a challenging task.


Where is the location underground where an earthquake starts?

The location underground where an earthquake starts is called the focus or hypocenter. It is the point within the Earth where the fault rupture begins and energy is released, generating seismic waves that propagate to the surface, causing an earthquake.


The point on earths surface where an earthquake starts is called?

Within the Earth, the focal point of the energy released in an earthquake is called the hypocentre or focus. This is where an earthquake actually begins. The place on the Earth's surface directly above this point is known as the epicentre.


What is the place of origin of an earthquake?

If you want to know what the name is, it is called the epicenter. If you want to know a location where all earthquakes originate, there isn't one. Earthquakes can occur along faultlines, or in the middle of a continent.
