Hopefully I helped ^~^

Answer 2

correct option is seismograph, tilt-meters, correlation spectrometers

Step-by-step explanation:

correct option is seismograph, tilt-meters, correlation spectrometers

Seismographs evaluate the movement in the crust of the earth. Volcanic eruptions are strongly linked to earthquake activities which also cause earthquakes & tremors, and seismographs are used for tracking volcanoes as well. Scientists used various instruments for measuring ground deformity (EDM, leveling, GPS and tilt), volcanic gas detection and measurement instruments (COSPEC)

A tiltmeter is a delicate instrument used to evaluate minute changes from lateral level on ground.

Volcanologist discovered an process to measure pollution which is termed as correlation spectrometers
