These percentages are somewhat misleading, however, because most of Earth’s rift zones are about 2 to 3 km (1.2 to 1.9 miles) below sea level, where volcanic activity is hard to detect. Because continental rocks are generally higher in silica, potassium, and sodium than are oceanic rocks, this process of assimilation and mixing can also play an important role in producing the wide range of compositions that occur in rocks from subduction volcanoes. Furthermore, any fractional crystallization tends to concentrate volatile elements in the residual melt.
Typically, volcanologists use seismic monitoring as their main indicator of imminent volcanic activity. Most subduction-related volcanoes are explosive and build stratovolcanoes, while rift volcanoes tend to be more effusive and build shield volcanoes, though there are exceptions to both these generalities.
