Natural phenomena, extending beyond what's strictly weather, often get lumped into "meteorology", including earthquakes, tsunamis, and volcanoes. One fairly well-known case is the Japan Meteorological Agency (JMA), whose remit includes not just weather by hydrology, seismology, and volcanology.

Generally: concerns of an extra-human, non-biological origin. E.g., JMA doesn't address pandemics.
