Mysterious Marsquakes Hint At A Volcanically Active Planet

Mysterious 'Marsquakes' Hint At A Volcanically Active Planet

Welcome Back To Theory Of Science
Researchers have analyzed a slew of recent temblors on the Red Planet and shown that these Marsquakes are probably caused by magma moving deep under the Martian surface. That’s evidence that Mars is still volcanically active, the researchers report October 27 in Nature Astronomy.Since touching down on Mars four years ago, NASA’s InSight lander has detected more than 1,000 Marsquakes (SN: 11/26/18). Its seismometer records seismic waves, which reveal information about a temblor’s size and location.Previous studies have determined that several Marsquakes originated from a swath of Martian terrain known as Cerberus Fossae (SN: 5/13/22). This region, which is particularly riddled with faults, is more than 1,000 kilometers from the InSight lander.But most of the Marsquakes linked to Cerberus Fossae so far have been pretty familiar, scientifically speaking, says Anna Mittelholz, a planetary scientist at Harvard University. Their seismic waves, which are low frequency, “are ones that look much more like what we see for an earthquake,” she says.Mittelholz and her colleagues have now analyzed a large sample of Marsquakes, including more than 1,000 high-frequency temblors, which look nothing like their earthly brethren. .in this video, we are looking into Mysterious 'Marsquakes' Hint At A Volcanically Active Planet
