1. Plural of geophone; sensitive instruments that detect and record ground vibrations and seismic waves, used in seismic surveys and earthquake monitoring.
Usage: technical; plural form; commonly used in geology, geophysics, and oil/gas exploration

Examples

• Geologists deployed arrays of geophones across the fault line to monitor seismic activity.
• The oil company used geophones to map underground rock formations during the seismic survey.
• Geophones are essential instruments for detecting even small ground vibrations caused by earthquakes.
• The research team buried hundreds of geophones in a grid pattern to collect detailed subsurface data.
• Modern geophones can transmit real-time data wirelessly to monitoring stations.
