Hecates Tholus is an extinct shield volcano in the Elysium Planitia area on the planet Mars . It lies north of the neighboring volcanoes Elysium Mons and Albor Tholus .
Hecates Tholus is 5.3 km high and 180 km in diameter at the base. Its complex caldera has a diameter of 10 km and is 600 m deep.
On the flanks there are radial trenches that have been eroded by liquid lava . A crater is visible on the northwestern edge, which was formed by a collapse after the magma chambers below were emptied. The western edge also shows traces of a past glaciation .
Evaluations by the Mars Express probe have shown that the volcanoes of the Elysium region were active for long periods of time. Major eruptions of Hecates Tholus occurred 1 billion and 300 and 100 million years ago.
