Earthquakes 1 recording station
What instrument is used to record earthquakes?
Earthquakes are recorded by instruments called seismographs. The recording they make is called a seismogram. The seismograph has a base that sets firmly in the ground, and a heavy weight that hangs free.
How can you tell how far away an earthquake was?
By looking at the amount of time between the P and S wave on a seismogram recorded on a seismograph, scientists can tell how far away the earthquake was from that location. However, they can’t tell in what direction from the seismograph the earthquake was, only how far away it was.
What type of waves are produced during an earthquake?
SEISMIC WAVES Two basic types of elastic waves or seismic waves are generated by an earthquake; these are body waves and surface waves. These waves cause shaking that is felt, and cause damage in various ways.
What is the location of an earthquake called?
location below the earth’s surface where the. earthquake starts is called the hypocenter, and the. location directly above it on the surface of the earth is. called the epicenter. Sometimes an earthquake has foreshocks. These are. smaller earthquakes that happen in the same place as. the larger earthquake that follows.
What kind of instrument is used to record an earthquake?
Earthquakes are recorded by instruments called seismographs. The recording they make is called a seismogram. The seismograph has a base that sets firmly in the ground, and a heavy weight that hangs free.
Where is the epicenter of an earthquake located?
The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
How are scientists able to determine the location of an earthquake?
Scientists then use a method called triangulation to determine exactly where the earthquake was (figure 6). It is called triangulation because a triangle has three sides, and it takes three seismographs to locate an earthquake.
When does an earthquake have a foreshock It is called?
Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock.
