The Science Hour

A new undersea volcano has appeared off the coast of East Africa. The sea floor between Madagascar and Mozambique has become increasingly seismically active in the last year. As well as the appearance of this active volcano, local islands are now experiencing frequent earthquakes. The causes of Indonesia’s Palu Bay tsunami last year are being examined thanks to social media. Videos taken as the tsunami hit have been analysed to determine wave heights and speeds and suggest possible causes. Scientists at a massive underground physics research facility in Italy are to stand trial over safety risks. The facility uses poisonous chemicals. There are concerns these could leak into drinking water supplies in the event of an earthquake. As scientists keep finding ever more fascinating facts about the invisible housemates that share our homes, we investigate what might be lurking in quiet household corners or under our beds. We head out on a microbial safari with expert tour guide Dr Jamie Lorimer from the University
