The following questions from schools are answered by Ben, Sylvia and Graham:
- How is a supervolcano formed?
- What causes a supervolcano to erupt and how much damage can that cause?
- What makes tectonic plates move?
- How does a pyroclastic flow stop?
- How can the Taupō supervolcano help us to understand volcanoes better?
- How do humans live with supervolcanoes?
- Could humans cause a supervolcano to erupt? Why/why not?
The following questions from schools are answered by Ben, Kiharoa, Bubs, and Graham:
- How many people would be involved in the monitoring (watching or studying) of the volcanoes in New Zealand?
- Does ash freeze if it is too high in the atmosphere?
- What technology do you think will be available in 50 year's time to monitor volcanoes to keep people and animals even safer?
- How did water fill up the caldera?
- Can you cook a meal in the hot pools at the top of the volcano?
- How hot is the magma in the chamber under Taupō?
- What would New Zealand’s most active or dangerous volcano be?
- Do other countries study our volcanoes. If so why?
- How do geologists measure when a supervolcano is going to erupt?
The following questions from schools are answered by Ben, Kiharoa, Sylvia, and Graham:
- We saw a GNS video on measuring sulfate and chloride ions in the crater lake. Do geologists measure these in Lake Taupō to track activity?
- How can we tell if a supervolcano is in a building phase, “potentially culminating, at some undetermined point in the future, in a large-scale eruption again in New Zealand"?
- Yellowstone is a famous supervolcano, is it more likely to erupt again before Lake Taupō caldera?
- Are all supervolcanoes rhyolite calderas?
- Does new pumice get generated without an eruption? It always seems to be floating on the lake.
- Could we get a supervolcano in Auckland?
- There is a geothermal electricity station near Taupō. Why don't we have any at Tongariro or Rotorua?QQQQQQQQQQQQQQQQQQ
