2014

What are the 3 signs of an impending volcanic eruption?
How can we tell when a volcano will erupt?
- An increase in the frequency and intensity of felt earthquakes.
- Noticeable steaming or fumarolic activity and new or enlarged areas of hot ground.
- Subtle swelling of the ground surface.
- Small changes in heat flow.
- Changes in the composition or relative abundances of fumarolic gases.
How did Mount Tavurvur was formed by tectonic plates?
As the Solomon Sea Plate sinks into the Earth it is melted by the heat of the planets interior. Some of the melted material then rises through the overlying South Bismarck Plate, fueling the volcanoes of New Britain.
How was the town of Rabaul destroyed?
Rabaul was the provincial capital and most important settlement in the province until it was destroyed in 1994 by falling ash from a volcanic eruption in its harbor. During the eruption ash was sent thousands of metres into the air, and the subsequent rain of ash caused 80% of the buildings in Rabaul to collapse.
When did Rabaul last erupt?

| Mountain type | Pyroclastic shield/Caldera |

Is Rabaul volcano active?
Rabaul volcano is one of the most active and most dangerous volcanoes in Papua New Guinea. Rabaul exploded violently in 1994 and devastated the lively city of Rabaul.
How can you tell if a volcano is active?
If a volcano has erupted since the last Ice Age—in the last 10,000 years or so—and is still showing activity like lava and ash flows or gas emissions, it’s considered to be active. If a volcano hasn’t erupted in the last 10,000 years, but scientists think it will erupt again, it’s considered dormant.
