What is going on under our feet? What are the big events that shape our world? Volcanoes and earthquakes are tectonic events that, over millions of years, change our planet. Our Earth is 4.56 billion years old and a lot has changed in that time! Join us for an exciting evening of dramatic volcanic eruptions, exploration of volcanoes in the middle of oceans and mountain building events!
A Pint of Lava and a Packet of Pumice, Please
Ever wondered if you would be here if it weren’t for volcanoes? If not, then this unusual talk is for you. I will cram as much volcanology into ten or fifteen minutes as is humanly possible. Why volcanoes matter; how your ancestors grew up in their shadow; where to take your next holiday; and how a super-eruption might ruin your day are among the questions answered.
Volcanic Islands: Deep Cause, Shallow Consequences
Many of the World's ocean islands have formed as a result of volcanic activity. Their global distribution is not random but controlled by processes at the Earth's core-mantle boundary. A unique example of the intimate link between Earth's deep and surface processes is spectacularly displayed in Galapagos. The volcanic islands, formed by a thermal anomaly anchored at the base of the mantle (2900 km), deflect ocean currents that in turn cause the unique diversity of fauna and flora. The equatorial position and biodiversity of Galapagos make it highly sensitive to changes in our planet's climate.
Earthquakes! Science, Hazard and Resilience
People are dying in earthquakes around the world at an ever increasing rate, mainly due to large populations concentrating in seismically active areas with unsafe buildings. In this talk I will describe the science we can use to work out what happens in an earthquake. I will then explain how we can recognise the effects of past earthquakes preserved in the landscape, and how their signs tell us about future earthquakes. Finally, I will end on an optimistic note by explaining the steps that can be taken to dramatically reduce earthquake-related fatalities.
