How Does A Seismograph Works? |
|
Answer» 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. Seismographs can detect quakes that are too small for humans to feel.
