Analyzing Low Frequency Seismic Events at Cerberus Fossae as Long Period Volcanic Quakes

The InSight Mission began acquiring the first seismic data on Mars in early 2019 and has detected hundreds of events. largest events recorded to date originate at Cerberus Fossae, a young volcanic region characterized by high volume, low viscosity lava flows. A handful Low Frequency (LF) quakes that share key attributes Long Period Earth's volcanoes are also traced Fossae. This study explores whether traditional source model simulates generation tremor as pressurized fluid makes its way through channel depth, can explain these atypical LF We consider wide range physical parameters including viscosity, ratio driving pressure lithostatic pressure, aspect channel, equilibrium opening. find produce observed signature, with combination low-viscosity magma volume flux ∼104 − 105 m3/s within an order-of-magnitude agreement Fossae flow properties deduced from analysis dimensions. It is impossible, however, this stage conclude or not likely explanation for Mars, results fluxes extreme Earth yet just bounds what been inferred therefore we cannot rule out active mechanism responsible
