The Volcano Observatory (Observatório Vulcanológico e Sismológico da Univ. dos Açores, CIVISA) recorded dozens of mostly small quakes at shallow depths between 1-15 km in an area about 6-7 km west of Furnas volcano, half way between the caldera lakes of Lagunas Fogo and do Congro. The largest were 6 earthquakes of magnitudes 3.0-3.6, some of which were felt by local inhabitants. At the moment, the activity is still continuing, but has decreased significantly. It is unclear whether the earthquakes are volcanic in origin or not. If so, they could have been caused by a small magma intrusion at the lower crust and indicate an early sign of possible re-awakening of the volcanic system.
Distribution of quakes as depth vs time (the smaller quakes have no given depth from the dataset)
Blue flames of burning sulfur: Ijen volcano in East Java has one of the most impressive sulfur deposits on earth. They are so hot that the sulfur often ignites - a mysterious display at night caught on camera.
