Well in old enough texts they might all be considered and described so. From our perspective, eclipses or comets -- astronomy, drought or famine -- meteorology or climatology, war -- fun one that could come into several, e.g. a climate change or drought could trigger a war with neighbours, perhaps to try and migrate. War is only one of those I think does fall under modern view of astrology as, like earthquakes, they can't be reliably predicted until inevitable. Comets like Halley's or solar eclipses can be predicted, with decent precision.
