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.
