Understanding the Anak Krakatau eruption - a podcast by BBC World Service

We have the latest from a year long investigation into the causes of the December 2018 Indonesian Tsunami. And we get a look at the first pictures from the Mayotte undersea volcano, which emerged earlier this year off the coast of East Africa.

As CrowdScience celebrates its third birthday, the team takes time to revisit some of our early episodes, and catch up with listeners to discover if the answers we uncovered changed the course of their lives? We hear from Zach, who has learned to let go of a possibly lost memory and Erin, who discovered technology could hold the key to finding the man of her dreams. And two years after he emailed to ask why he couldn’t kick his habit, we ash Sharif whether he has finally managed to stop smoking?
