Volcanic activity can influence landforms through input of sediment into a system. For example, an explosive volcanic eruption could produce a pyroclastic flow which may enter coastal systems. The sudden input of a large amount of sediment may create a new landform such as a delta, this can be seen in the Soufriere Hills, Montserrat 1996 in which a pyroclastic flow entered the sea from the Tar river valley, to form a shallow shelf for sediment to accumulate, creating a low energy coastal system.  

A tombolo is another example of a landform that could be created due to a pyroclastic flow. An example of this is in Italy where the islands of Vulcano…
