marsquake









































a marsquake is a quake which, much like an earthquake, would be a shaking of the surface or interior of the planet mars as a result of the sudden release of energy in the planet's interior, such as the result of plate tectonics, which most quakes on earth originate from, or possibly from hotspots such as olympus mons or the tharsis montes. the detection and analysis of marsquakes could be informative to probing the interior structure of mars, as well as identifying whether any of mars's many volcanoes continue to be volcanically active or not.

extinct volcanoes are those that scientists consider unlikely to erupt again because the volcano no longer has a magma supply. examples of extinct volcanoes are many volcanoes on the hawaiian – emperor seamount chain in the pacific ocean (although some volcanoes at the eastern end of the chain are active), hohentwiel in germany, shiprock in new mexico, zuidwal volcano in the netherlands and many volcanoes in italy like monte vulture. edinburgh castle in scotland is famously located atop an extinct volcano. otherwise, whether a volcano is truly extinct is often difficult to determine. since "supervolcano" calderas can have eruptive lifespans sometimes measured in millions of years, a caldera that has not produced an eruption in tens of thousands of years is likely to be considered dormant instead of extinct. some volcanologists refer to extinct volcanoes as inactive, though the term is now more commonly used for dormant volcanoes once thought to be extinct.
