they know by underground sensors that tell them that earthquakes are coming to a certain or not certain area.

Sort of! The point of maximum effect on the land surface is the earthquake's Epicentre, and the unfortunate residents can tell you where that was. The origin of the 'quake, i.e. the centre of the action that caused the tremors, is its Focus, and is usually deep below ground. The earthquake is timed as it passes seismographs around the world, and because the speed of the vibration through the planet is known, the location of the focus can be calculated from triangulating distances, which are speed/time. Obviously it won't be that simple, but that is the general principle.
What information can scientists obtain by studying seismographs from different locations? A.the location and strength of the earthquakeB.when the next earthquake is going to happenC.the direction of motion of tectonic platesD.the amount of damage caused by an earthquake i need your help can you please click "IMPROVE ANSWER" to tell me the answer....... Hello I am here to help. The answer is A. :D I am a student and took this test weeks ago!
Scientists can tell whether organisms are closely related by comparing their DNA. This will allow then to look at various traits and features so as to compare the relationship between organisms.
Some scientists are people that explore the world and try to tell us about the planet but we don't understand!
A dumb scientist. The only person you should tell if you found somthing worth sharing is the news reporter!

they do it by using a seismograph
Seismographs
The word epicenter is typically heard after an earthquake has occurred. This word refers to the area of first impact by the earthquake, and is used to tell how big the earthquake was.
well they can tell because there smart and they have a divice im only 11 though
How far away the epicenter is.
When an earthquake occurs, data from one seismograph can tell you the arrival time of seismic waves, the distance from the earthquake epicenter to the seismograph, and the magnitude of the earthquake. By analyzing this data, scientists can determine the location and strength of the earthquake.
the china earthquake obviously happened in china but it happend in a place called Sichuan. Can anyboy else tell me why did the earthquake happen?
how far away you are from the focus of an earthquake
The redshift tells scientists how fast a star or galaxy is moving away from us.
yes but there was not an early warning system so they could not tell the people.
A seismograph is a device that measures and records seismic waves caused by earthquakes or other sources. It provides information about the magnitude, location, and depth of an earthquake by detecting the vibrations of the Earth's surface. Scientists use seismograph data to study earthquakes and assess seismic hazards in different regions.
It makes a lower frequency than something coming to us
