What can you learn from only one seismogram?
4. One seismogram tells you how far away the epicenter was and how strong the earthquake was.
What is a safe distance from a fault line?
Phivolcs now recommends avoiding construction within 5 meters on each side of a fault trace, or a total width of 10 meters. We may call this the ideal “10-meter wide no-build zone” in the vicinity of a fault.
What is difference between seismograph and Richter Scale?
A seismograph is what scientists use to actually measure the earthquake and the Richter scale is a way of putting the data into an understandable context. The Richter scale is a logarithmic scale which means the number on the scale measure factors of ten.
What is seismologist?
Seismology is the scientific study of earthquakes and related phenomena, such as volcanic eruptions. Seismologists also apply what they learn from studying the Earth’s structure and other geological events, such as tsunamis, for commercial and other purposes, such as detecting nuclear explosions.
What are 3 things a seismologist does?
Seismologists study earthquakes and their results, like tsunamis, and landslides. They may also monitor active volcanoes for tremors and signs of an impending eruption. They use seismographs and computer equipment to collect and analyze data on seismic events.

Who was the first seismologist?
Chang Heng
Who named earthquakes?
The cause of earthquakes was stated correctly in 1760 by British engineer John Michell, one of the first fathers of seismology, in a memoir where he wrote that earthquakes and the waves of energy that they make are caused by “shifting masses of rock miles below the surface”.
When was first earthquake recorded?
The earliest earthquake for which we have descriptive information occurred in China in 1177 B.C. The Chinese earthquake catalog describes several dozen large earthquakes in China during the next few thousand years.
Who is known as the father of seismology?
John Milne
What is seismology Class 8?
Answer: Seismology is the scientific study of earthquakes and their related phenomena.
Which is known as seismic wave?
A seismic wave is an elastic wave generated by an impulse such as an earthquake or an explosion. Seismic waves may travel either along or near the earth’s surface (Rayleigh and Love waves) or through the earth’s interior (P and S waves).
What is common to both P waves and S-waves?
Answer: P-waves and S-waves are waves of the body that travel across the globe. On average, P-waves move 60% faster than S-waves, since the interior of the Earth does not respond to both of them in the same way. Compression waves that apply a force in the direction of propagation are P-waves.
