How do geographers research volcanoes? Dr Tom Pering explains in this podcast
On June 3 2018, Guatemala’s Fuego volcano erupted. It is the strongest eruption in 44 years. The volcano set off lahars – fast flowing mixtures of rock, debris, ash and water – which buried nearby villages. Guatemala is the biggest economy in Central America. Yet, according to World Bank, it has one of the highest inequality rates in Latin America. Poverty, malnutrition and maternal-child mortality rates in rural and indigenous regions. Of all the people living in poverty, 52% are indigenous.

Only a few weeks previously, Hawaii’s Kilauea volcano erupted on May 4, and in Indonesia Mount Merapi volcano has been erupting since mid-May. What drives such activity? Given that they often impact communities locally, national and internally it is important that volcanoes are monitored. Volcanic gas emissions are the driver of the vast majority of volcanic activities. In this podcast Dr Tom Pering from the Department of Geography, University of Sheffield discusses his research into using smartphone technology as a research tool to monitor these gazes and expand how geographers engage with hazards. You can follow Dr Pering’s research on Twitter.
Listen to the podcast and answer the following questions
Why is it important to know baseline gas emissions of volcanoes?
How have volcanic gases been measured
How have scientists changed how they monitor gas emissions?
What is remote sensing?
What is the correlation spectrometer?
What are the social and economic restrictions to monitoring volcanoes?
Dr Tom Pering is currently researching Massay volcano, Nicaragua. It is a complex volcano that is composed of a nested set of calderas and crates – the largest. Watch this vlog by Dr Tom Pering, and describe the features showcased and distinctive hazards generated. You can read about this research on Dr Pering's blog.
What is it like to live with volcanic gases? This video explores life near the Massay volcano in Nicaragua. Watch the film take notes on how the community builds lives in this hazardous landscape. How have they adapted and build resilience? What are the risks? Consider your answers in relation to the economy, health, infrastructure, food and water security, and social life
If time permits, read the following articles and produce notes to produce a full case study of the Massay volcano.
