Nyiragongo Eruption

Bbc World Service
About this episode

The latest Nyiragongo eruption was not entirely unexpected, the volcano’s lava lake inside the crater had been building up for years. Local volcanologists say it was only a matter of time before an eruption occurred. The big concern was where the flank of the volcano would be breached as the city of Goma rests under the volcano and there are potential fissures even within the town. However there are still questions over the effectiveness of seismic monitoring in the area, North Kivu. The Goma observatory has been unable to carry out this work due to a lack of funding. And monitoring is further complicated by the region’s long running civil war, with rebel groups often camped around the volcano. We hear from Dario Tadesco and Cindy Ebinger. Who have both been monitoring developments.

Cyclone Yass was the second Cyclone to hit India within a week. Are these events becoming more common and are they related to rises in global temperatures? Climatologist Roxy Koll has been monitoring the situation.

Greenland’s pristine glaciers might not be so pristine. Jemma Wadham from Bristol university and her team have found unexpectedly high levels of Mercury in meltwaters - similar to those from industrial pollution. They say research now needs to focus on the impact for wildlife and people in the Arctic region.

And the elusive Sowerby’s beaked Whale doesn’t travel very much despite pockets of the species being found across the Atlantic. Kerri Smith has been researching this species, which is rarely seen alive. Using samples from whales beached or caught accidentally she was able to build up a picture of their distribution.

As millions more of us move to live in densely populated cities, we almost inevitably face living in closer proximity to our neighbours. Neighbour noise can certainly be a source of annoyance – but could it even be damaging to our health?

Increasing evidence suggests that unwanted noise can cause sleep deprivation, distraction and annoyance, as presenter Anand Jagatia finds out. He discovers that noise annoyance has a small but significant impact on our wider health – including our cardiovascular system – but that annoyance is not necessarily down to sound alone. Factors such as perception of the neighbourhood and relationships with our neighbours also play a part.

CrowdScience has examined living with unwanted noises before, and we revisit our trip to the acoustics lab at the University of Salford in Manchester, UK. Here, we meet the researchers and engineers investigating the best ways to make our homes more pleasant for our ears whilst still maintaining the ‘buzz’ of city life.
