Recently, scientists looked at data collected by NASA’s InSight lander to learn more about seismic activity on Mars, known as marsquakes. The data show that the marsquakes all started from the same location on the planet. This discovery was surprising to scientists, as they expected that the marsquakes would originate from all over the planet because of the cooling of the planet’s surface. Now, scientists believe that there could be areas of active magma flows deep beneath the planet’s surface that trigger the marsquakes.
