Two Billion Year Eruptions?

A meteorite from Mars indicates that it's possible a volcano on Mars - most likely Olympus Mons - erupted constantly for two billion years.

This apparently ridiculous fact is possible because Mars has little to no tectonic activity, meaning hotspots under the crust don't move. (Which is also why Olympus Mons is ridiculously huge but not very steep).
