However, there are still small clouds of ash hanging in the sky because of it. It was a very unlucky year that year because it happened to be an El Nino year. The volcanic eruption just exasperated the bad situation. Tephra is the discharge that comes out of the volcano. It comes in three different forms, accessory, accidental, and juvenile.
Accessory is made up of the volcanic cone that is shot everywhere when the volcano erupts.
Accidental is sub-volcanic rock. It is carried up from the mantle or the lower part of the crust. Juvenile is made from pure magma. When the volcano erupts, shards of magma are shot miles high. Tephra gets a different name according to its size and weight and color.
