Columbia & Ecuador Twin Volcanoes - Higher Alerts EDIS CODE: VA-20140502-43593-MLC Date & Time: 2014-05-02 11:01:11 [UTC] Area: MultiCountries, Columbia and Ecuador, Cerro Negro de Mayasquer volcano The alert level of the twin-volcanoes Cerro Negro and Chiles has been raised to yellow in response to an ongoing seismic crisis and deformation that has been detected since November 2013, when a new monitoring network had been installed. INGEOMINAS reported that seismic activity has remained elevated and that so far, more than 60,000 small earthquakes at shallow depths (1-6 km) have been recorded since November 2013. The epicenters were between 3-5 km SW of the Chiles volcano, while deformation affects neighboring Cerro Negro volcano to the west. Several of them were felt by people living close by. The largest quake so far was a magnitude 4.5 event that was felt widely. Colombian volcanologists mapped the risk zones for each of the two volcanoes. Neither of them has recorded historical eruptions and little is known about their activity. Whether or not the current unrest leads to an eruption in a near or medium-term future (months, years), and if so, which of the two volcanoes would be involved is unknown. Since the location of the volcanoes is at the Ecuadorian border, the Ecuadorian civil defense SNGR (Secretaria National Management Riesgos) also raised an yellow alert for the potentially affected area in Ecuador.
