Volcanic mudflows can be detected remotely by monitoring:
A) characteristic rumbling produced as they rush down valleys
B) rapid changes in groundwater chemistry and volcanic gas conten
C) dropping of the ground surface as mudflows are erupted from beneath the volcano
Groundwater Chemistry
The study of the chemical characteristics and reactions of groundwater, including dissolved minerals, pollution, and the movement of contaminants.
Ground Surface
The top layer of the earth's crust that we walk on and interact with in our everyday lives.
Volcanic Gas
Gases emitted from a volcano, including water vapor, carbon dioxide, sulfur dioxide, hydrogen sulfide, and other volcanic gases.

Final Answer :
A
Explanation :
Volcanic mudflows, also known as lahars, produce a characteristic rumbling sound as they rush down valleys, which can be detected remotely. This sound is generated by the mixture of rock, ash, mud, and water moving rapidly, and it is distinct enough to be used as an indicator of an occurring mudflow.
