section::::heat source.









































io's main source of internal heat comes from the tidal forces generated by jupiter's gravitational pull. this external heating differs from the internal heat source for volcanism on earth, which is a result of radioactive isotope decay and residual heat from accretion. in the earth, these internal heat sources drive mantle convection, which in turn causes volcanism through plate tectonics.
volcanology of io
the subduction of the nazca plate beneath the south america plate causes volcanism along the western margin of south america. this volcanism is distributed over three volcanic belts, the northern volcanic zone, the central volcanic zone and the southern volcanic zone. among these, the central volcanic zone includes the volcanoes of southern peru, a country with over 300 volcanoes. of these, el misti, huaynaputina, sabancaya, ticsani, tutupaca, ubinas and yucamane have been active during historical time. geothermal manifestations such as fumaroles, geysers and hot springs also occur in the country. in general though volcanism in peru is poorly known.
