Volcanoes also inject water vapor into the upper atmosphere, which can lead to night-shining clouds.

In 1883, the eruption of the Indonesian volcano Mount Krakatau (Krakatoa) caused widespread reverberations in climate, including night-shining clouds like those seen from the United Kingdom in this 1885 sketch by William Ascroft, an artist who recorded phenomena thought to have been linked to the eruption.
