What do scientists use seismographs for?
A seismograph is the device that scientists use to measure earthquakes. The goal of a seismograph is to accurately record the motion of the ground during a quake.
What are two things seismometers can tell a scientist?
Seismometer are used by seismologists to measure and record seismic waves. By studying seismic waves, geologists can map the interior of the Earth, and measure and locate earthquakes and other ground motions. The term seismograph is usually interchangeable, but seismometer seems to be a more common usage.
What did scientists discover with seismometers?
Seismographs can detect quakes that are too small for humans to feel. During an earthquake, ground-shaking seismic waves radiate outward from the quake source, called the epicenter. Different types of seismic waves travel at different speeds and through different parts of the Earth during a quake.
What are seismometers used for?
A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with “seismograph”. Seismographs are instruments used to record the motion of the ground during an earthquake.
How does seismograph help in studying the earthquake waves?
Seismologists study earthquakes by looking at the damage that was caused and by using seismometers. A seismometer is an instrument that records the shaking of the Earth’s surface caused by seismic waves. The term seismograph usually refers to the combined seismometer and recording device.
What is a seismograph explain its working with the help of diagram?
An instrument used for recording the vibrations caused by earthquakes is known as seismograph or seismometer. The vibrations are recorded on a strip of paper and the diagram produced is known as a seismogram. Numerous models of seismographs are in current use.
