Roundup of Global Volcanic Activity

Cerro Negro de Mayasquer volcano (Colombia): magnitude 5.8 earthquake, alert level raised Orange alert has been declared for the volcanic complex at the Colombia-Ecuador border, after a magnitude 5.8 earthquake occurred under the volcano last Monday. This earthquake, located at shallow 10 km depth southwest of the Chiles cone, seems to be directly linked to the ongoing crisis at the volcano. The volcano has recently been showing increased signs of volcanic unrest and inflation. This could be the sign of magma rising with the volcano and result in an eruption, although it is not possible to quantify how likely this might be.
