seismographic
Measuring earth's tremors
Seismographic means relating to or recorded by a seismograph—an instrument that detects and measures ground vibrations, especially earthquakes.
The term applies to the equipment, its readings, or the data it produces: seismographic stations across the region, seismographic evidence of underground testing.
Figuratively, something seismographic registers subtle shifts or tremors in any domain.
