State: Colombia | Coordinates: 34.89, -75.32 | Eruption: Strombolian
In Colombia, the activity of Nevado del Ruiz volcano is slowly but steadily increasing. The ash eruptions are becoming more frequent and are causing concern among the residents of the volcano. Images of the eruptions are now being shared on social media. Most recently, an ash cloud reached 5800 meters today. Last week’s SGC bulletin said that seismicity had continued to increase. The strongest earthquake had a magnitude of 2.1 at a depth of only 3.1 km. Furthermore, a slight increase in ground deformation was recorded. The gas emission was high. The researchers consider a further increase of activity possible. Nevado del Ruiz is particularly dangerous because its summit is glaciated. Meltwater could increase explosive activity, or trigger lahars.
