Nevado del Ruiz Volcano Update Potential for a Large Eruption Alert Level Increased

a In the last week, the number of seismic events at one of the planet's most historically deadly volcanoes increased to record levels, with 11,000 such events occurring on a single day. And, there appears to be a new intrusion of magma pushing its way up through the glacier covered Nevado del Ruiz volcano in Colombia. As a result, its alert level was raised from yellow to orange for the first time in slightly more than a decade. This video will discuss the ongoing situation and what might happen next at this volcano. • Important Nevado del Ruiz links: • [1] Nevado del Ruiz Volcano Hazard Map: https://recordcenter.sgc.gov.co/B1/11... • [2] Unidad Nacional para Gestión del Riesgo de Desastres: http://portal.gestiondelriesgo.gov.co/ • [3] Servicio Geológico Colombiano: https://www.sgc.gov.co/ • Thumbnail Photo Credit: iStock.com, Nicolas Socadagui, https://www.istockphoto.com/photo/vol....
