Volcanoes - which go back to the earliest days of earth as a planet - were here billions of years before man was. Man has never know a time without volcanoes, hence there is no "year that volcanoes got noticed".
Early map makers noticed the location of volcanoes were located along plate boundaries.
Volcanoes can erupt at any time of year.
