Earthquake magnitude is a quantitative measure of the energy released at the source of an earthquake, with each whole number increase on the scale representing a tenfold increase in amplitude and roughly 31.6 times more energy release. It is typically measured using the Richter scale or the moment magnitude scale, with the latter providing a more accurate representation for larger earthquakes.
Concept
Waveform analysis is the study and interpretation of the shape and characteristics of waveforms to understand the underlying physical phenomena or signals they represent. It is crucial in fields like electrical engineering, acoustics, and medical diagnostics to extract meaningful information from complex signals.
Concept
Refraction is the bending of light as it passes from one medium to another due to a change in its speed, while reflection is the bouncing back of light from a surface. Both phenomena are governed by the laws of optics and are crucial for understanding how light interacts with different materials.

Ground motion refers to the movement of the earth's surface due to seismic waves generated by phenomena such as earthquakes, volcanic activity, or artificial explosions. It is a critical factor in assessing seismic hazards and designing structures to withstand potential impacts from these natural events.
Concept
The Magnitude Scale is a logarithmic scale used to quantify the size of an earthquake, measuring the energy released at the source of the earthquake. It allows for a standardized comparison of earthquake sizes and is instrumental in assessing potential damage and necessary response efforts.
Concept
Seismic tomography is a technique used to image the internal structure of the Earth by analyzing the propagation of seismic waves generated by earthquakes or artificial sources.
