Back in historical times, volcanoes played a crucial role in the evolution of the planet and early life, and are constantly reshaping the morphology of Planet Earth. 

Today, about 500 active volcanoes presently exist on the Earth’s surface, with some 50 erupting each year, and more than 800 million people living within 100 kilometres (60 miles) of an active volcano. As populations continue to grow around volcanoes, these impact events will likely continue to affect communities. 

With modern society heading into uncharted territory as the world grapples with unprecedented climate change effects, many concepts adopted by policymakers and scientists to deal with volcano-related hazards will quickly become outdated, and hence making ongoing research so crucial. 

While extensive research has been done on explosive eruptions, there has been limited studies on how lava flows are impacting communities. These streams of molten rock are one of the most common volcanic hazards and can be disastrous for communities. 

On this episode of Climate Connections, Dr Elinor Meredith, Research Fellow in Volcanic Risk, University of Twente and Susanna Jenkins, Associate Professor, Earth Observatory of Singapore, NTU share insights from their extensive study on the frequency and severity of these lava flow impact events, and whether they are an increasing threat to communities.
