After the news of a sizable earthquake under Nevado del Huila, we can add Nevado del Ruiz to the list of volcanoes that have been shaken up recently. There was a M5.7 earthquake underneath Ruiz on Saturday (9/13), which is a pretty significant event. However, the earthquake was located at over 100 km depth, so likely it is not related to any magma movement at Ruiz. I will keep my eyes open for any reports of increasing unrest at Ruiz and at Huila in the coming days.
