What are the main responsibilities of a seismologist?
Studies earthquakes, analyzes earthquake data, gives reports on current earthquakes, interprets the composition of the Earth, evaluates earthquake dangers, determines earthquake magnitude, analyzes faults and fractures.
Explain the significance of a seismograph in relation to earthquakes.
It detects and records seismic waves, helps locate the epicenter, determines energy release, and earthquake depth.
Describe the characteristics of a seismogram.
The recording made by a seismograph.
What is the definition of an epicenter?
The location where the earthquake wave first hits the surface, directly above the focus.
Discuss the characteristics of P-Waves in earthquakes.
Type of body wave, first to reach the seismograph, stretches and compresses the Earth's crust, moves back and forth, slows down in liquids.
Explain the properties of S-Waves in seismic activity.
Shear or secondary waves, ground shaking perpendicular to wave direction, cannot travel through outer core or liquids.
Learn about the role of a seismologist in studying earthquakes, analyzing data, and evaluating earthquake dangers. Understand the function of a seismograph as a tool used to detect and record seismic waves.
