InSight Lander Detects Mars Quakes

On April 23rd 2019, NASA announced that its InSight lander has detected the first seismic activity on Mars, which they are calling a, "Marsquake." The seismic event was recorded on April 6th using its SEIS or Seismic Experiment for Interior Structure instrument. Researchers at Jet Propulsion Laboratory in California say that the, "Marsquake," was equal to a 2.5 quake here on Earth. Since Mars is believed to have no plate tectonics, the origin of the quake is yet to be determined.
