A common effect of volcanic eruptions are land slides.
"Debris flows of mud, rock, and water travel down the flank and into valleys and streams at velocities of 20 mph to 40 mph."

Pyroclastic flows are mixtures of hot gas, ash and other volcanic rocks travelling very quickly down the slopes of volcanoes. They are one of the most dangerous hazards posed by volcanoes.
eruptions can inject massive quantities of ash into the atmosphere, greatly "reducing the solar heating of the Earth and potentially interrupting the global food supply for several years."

"how explosive a volcano is depends on how runny or sticky the magma is."
"When the plunging plate gets deep enough inside the mantle, some of the rock on the overlying plate melts and forms magma that can move upward and erupt at the Earth's surface."
"Stratovolcanoes build from eruptions of lava and tephra that pile in layers or strata, much like layers of cake and frosting."
The Cindercone volcano is the smallest and most common type of volcano.
The Galapagos islands were formed from shield volcanoes.
Cindercone volcanoes mainly shoot out pea sized tephra.
The famous Ring of Fire, in the Pacific Ocean region, is made up of Stratovolcanoes.
Cindercone volcanoes have the largest crater at the top.
