Can the weather trigger a volcano?
from Unexpected Elements · host BBC World Service
Which came first the volcano or the rain? Volcanic eruptions are known to influence global climate systems, even leading to the cooling of the planet. However local weather conditions can also influence the timing and ferocity of volcanic eruptions. As volcanologist Jenni Barclay explains rainwater can contribute to volcanic instability and even increase the explosiveness of eruptions.Syria has been experiencing civil war for more than 10 years. Many people have left including many of the country's scientists. We speak with 3 exiled Syrian scientists Shaher Abdullateef, Abdulkader Rashwani, and Abdul Hafez about their current work, which involves working with other academics and students in Syria sometimes remotely and sometimes directly.New findings from Chile reveal an unknown Tsunami emanating from an earthquake there in the 1700s. Historical records mention other ones, but not this one. Geoscientist Emma Hocking found the evidence in layers of sand.And we discuss the development of tiny robot-like structures made from frog cells, they can move and build other copies of themselves. Sam Kreigman and Michael Levin explain how.And, Life is full of choices, from the mundane (like what to wear today) to the critical (how should we deal with the pandemic?). So how can we make the best decisions? That’s what listener David wants to know.To investigate, Caroline Steel learns how being smarter doesn’t necessarily make you a good decision maker. She speaks to researchers about the importance of ‘gut feelings’ – and how certain people with no intuition whatsoever can struggle to make choices. She also learns why it’s easier to give advice to other people than to follow it yourself, and how we can work together to make the best decisions in a group.(Image: Eruption of Semeru.
