Simulate seismic waves

What is seismic wave? Seismic wave refers to the vibration radiated from the earthquake source to the surrounding area, that is, the elastic wave radiated from the source to the surrounding area. Earthquake waves are mainly divided into two categories: body waves and surface waves. Body waves include longitudinal waves (P-waves) and transverse waves (S-waves), while surface waves include Rayleigh waves and Rayleigh waves.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

1. Seismic waves mainly include longitudinal and transverse waves. The wave whose vibration direction is consistent with the propagation direction is a longitudinal wave (P-wave). The wave whose vibration direction is perpendicular to the propagation direction is a transverse wave (S-wave). two Magnitude and Intensity: The degree of earthquake damage to the ground and buildings during an earthquake is called seismic intensity. three Zhang Heng and His Seismograph: Over 1800 years ago, Chinese scientist and writer Zhang Heng created the world's earliest seismograph for measuring earthquakes.
