Insight's scientific mission ended in December 2022, after the lander sat quietly listening to "the pulse of Mars" for four years.
In that time, the probe recorded more than 1,319 quakes.
By measuring how fast seismic waves travel, scientists have worked out what material they are most likely to be moving through.
"These are actually the same techniques we use to prospect for water on Earth, or to look for oil and gas," explained Prof Michael Manga, from the University of California, Berkeley, who was involved in the research.
The analysis revealed reservoirs of water at depths of about six to 12 miles (10 to 20km) in the Martian crust.
