Different types of magmas produce different types of hazards. The creation of scoria really begins with the magma beneath the Earths surface. These volcanoes often occur in clusters that cover large areas, resulting in very widespread volcanic fields. This action can produce a ground cover of scoria all around the volcanic vent, with the heaviest deposits on the downwind side. The color difference is due to the difference in their composition. S. philippinensis Plant growth can be reduced, leaves covered in mould may die prematurely and there may be a reduction in fruit yield.[3].
