Loloru volcano is a large shield volcano in SE Bougainville Island.
It is composed mainly of airfall tephra and thick pyroclastic flow deposits and together with the nearby Takuan complex covers about 60% of the southern half of Bougainville Island.
The smooth flanks of Lorou's shield are cut by deep radiating valleys in all directions. The summit of Loloru volcano contains 2 nested calderas 3.5 and 2 km wide and a forested andesitic lava dome at the SW edge of the caldera. The caldera has been the source of many violent explosive eruptions of Loloru in the past 10,000 years, depositing large ignimbrite deposits on southern Bougainville Island. The most recent explosion was about 3000 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.
