A Patera volcano is dominated by an irregular or complex caldera with scalloped edges, surrounded by very gentle slopes of usually less than one degree. The alternating lava flows, pyroclastic flows, and lahars form multiple strata over many years and eruptions. these volcanoes are also shaped like a cone, but are formed from layers of lava over many years. A Tholus volcano is an isolated domal mountain with a central crater, having slopes that are usually steeper than those associated with both Mons and Peterae volcanoes. For these to form lava/magma is very hot and runny and they often many layers. There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes.

Once the rock does rupture under the stress, it releases the energy it built up over those many years in the form of a seismic wave - an earthquake occurs. The tectonic plate boundaries become evident from the data when you look at the visualization. The magma is very acidic and, therefore, extremely viscous. This is a very common type of volcano in many parts of the world, especially in volcanic hot zones. There are about 1500 volcanoes on earth, and about 500 of those are active. Answer (1 of 2): One reason is magma pushing up through the tectonic plates, sometimes moved and opened by earthquakes, others just push up over many years, until finally they erupt.
