Was the AD 365 Mediterranean Earthquake Normal?
The great AD 365 earthquake at Crete has implied a locked Hellenic subduction zone that can produce more earthquakes to threaten Mediterranean coastlines. But what if wasn’t a subduction zone event?

Is Atmospheric Oxygen a Planetary Signature for Life?
While some Earth-like worlds can generate significant O2 only by biology, “waterworlds” and “desert worlds” can build up O2 even without life because of chemical changes from atmosphere loss to space.
