Earthquake Terminology and Concepts

Surface waves are a type of seismic wave created by both P (Primary) and S (Secondary) waves, traveling along the Earth's surface.
Geologists analyze seismic data from various global sources to enhance their understanding of earthquakes.
The epicenter of an earthquake is defined as the point on the Earth's surface directly above the earthquake's focus.

Seismology Practices

Seismographs are essential tools in locating earthquakes; each star on the map indicates the position of a seismograph that recorded seismic activity.
The Mercalli scale evaluates earthquakes based on the level of damage inflicted on structures and the intensity experienced by people.

Measuring Earthquake Magnitude

The moment magnitude scale measures the energy released during an earthquake, providing an estimation of its overall strength.
The Richter scale quantifies earthquake magnitude, indicating an increase as the potential for damage rises.

Faults and Stress

When stress accumulates at geological faults, the surrounding rock can bend or fracture, leading to potential seismic activity.
S waves (Secondary waves) and P waves (Primary waves) are both seismic waves that cause ground shaking during an earthquake.
