‘Blue alert’ up as disaster agencies set 24-hour watch on Mayon

THE National Disaster Risk Reduction and Management Council (NDRRMC) raised the blue alert on Mayon after a series of phreatic explosions were monitored from the country’s most active volcano on Monday.

NDRRMC Executive Director Ricardo Jalad said a blue alert would mean that all concerned agencies under the NDRRMC would render duty at the operations center on a 24-hour rotational basis.
