An #eruption of #Nyiragongo #volcano (#DRC) began in the evening of May 22. #Meteosat satellite data (from @CIRA_CSU) show a strong thermal anomaly appearing at 17:15 UTC, and a small #volcanic plume amidst widespread regional convection. Follow @CharlesBalagizi for updates. If you're looking for background info on #Nyiragongo and its previous flank #eruptions in 1977 and 2002, there's a collection of papers in the Italian Acta Vulcanologica journal available here (with free PDFs):
