The current scientific consensus regarding Olympus Mons, the largest volcano in our solar system, is that it is likely a dormant volcano rather than a completely extinct one. While much of its structural growth occurred during the Hesperian period, geological evidence suggests that volcanic activity on Mars may have continued much more recently than previously thought.
Observations of lava flows on the surface of Olympus Mons indicate that some volcanic eruptions may have occurred as recently as tens of millions of years ago. On a geological timescale, this is considered very recent. This suggests that the volcano may still possess a source of internal heat capable of generating magma, even if it is not currently active.
Because we cannot monitor the internal thermal state of Mars in real time like we can with Earth, scientists cannot definitively rule out the possibility of future eruptions. Therefore, while the volcano is not currently erupting, it is classified as potentially dormant.
