Iztaccíhuatl volcano (also spelled Ixtaccíhuatl) is a massive andesitic stratovolcano next to the famous neighbor Popocatépetl volcano. It is the 3rd highest mountain of Mexico.
Iztaccíhuatl has the profile of a sleeping woman when seen from the Valley of Mexico, which gave it its name meaning "Woman in White", referring also to the Ayoloco glacier covering its summit. Geologically, it is the predecessor volcano of Popocatépetl and now in its final stages of infrequent activity, with some activity sometime less than 11,000 years ago.
Introduction to Plate Tectonics: The Earth's upper, rigid layer is broken into several plates which are in constant motion to one another. Most earthquakes and volcanoes occur as result of these plate boundaries.
Volcanic crisis at Sakurajima - updates: A strong earthquake swarm and increased inflation were detected in August 2015 and triggered authorities to raise the alert level, as volcanologists think that a larger eruption could follow. News and updates on the events can be found on this page.
