A huge ocean wave has been filmed from beneath the surface, revealing features never before captured on camera. The remarkable video, which will be shown as part of the BBC Natural History Unit’s new series South Pacific, was filmed in super slow motion using a high-definition camera. It reveals the hidden power of a four-metre-tall monster barrel wave. It also shows the first images of underwater spiralling vortices created by the wave’s action. The wave was filmed off the coast of Pohnpei in the Caroline Islands, part of the Federated State of Micronesia. The location is well known in the international surf community. Some of the biggest waves in the world break on South Pacific islands. The storm swells that create these waves travel more than 5,000km to break on their shorelines.

Scientists in the Democratic Republic of Congo have recorded significant increased volcanic activity around Goma in the east of the country. Half of the city was destroyed in 2002 after the nearest of two volcanoes, Mount Nyiragongo, erupted. Now Mount Nyamulagira, which lies 25km (16 miles) from Goma, may soon erupt. Scientist Dieudonne Wafula told the BBC if it did erupt, there would not be an immediate threat to Goma, but some key rural roads could be cut off.
