Surface Wave Detection Method

Surface Wave Detection is a geophysical exploration technique that utilizes the wave dispersion characteristics of surface waves, primarily Rayleigh waves, to map subsurface layers. This method is categorized into two main approaches:

1. Active Source Detection (MASW)

• What is it? A method using artificial vibrations to analyze shallow geological layers.
• How it works: Vibrations from a hammer, weight drop, or vibroseis truck are recorded by geophones.
• Applications: Ideal for studying shallow layers (<15m) in urban engineering, pipeline detection, and infrastructure projects.

2. Passive Source Detection (ESPAC)

• What is it? A method relying on natural ground vibrations for deep-layer analysis.
• How it works: Ambient vibrations are recorded and analyzed to determine S-wave velocity structures.
• Applications: Suitable for deep strata exploration (up to 10 km), including mineral resource detection and oil reservoir mapping.

These complementary techniques offer a comprehensive understanding of subsurface structures, essential for reliable seismic assessments.
