Turrialba (Costa Rica) - Report for 7 November-13 November 2018

OVSICORI-UNA reported that during 6-11 November low-level ash-and-gas emissions at Turrialba were continuous, though occasionally punctuated by energetic explosions which elevated the plumes as high as 500 m above the crater rim.
The emission drifted towards the Valle Central.
Ashfall was reported in several areas downwind including Cascajal de Coronado, Desamparados (35 km WSW), San Antonio, Guadalupe (32 km WSW), Sabanilla, San Pedro Montes de Oca, Moravia (31 km WSW), Heredia (38 km W), and Coronado (San Josť, 35 km WSW).
Emissions likely continued on 12 November, though inclement weather did not allow for visual confirmation.
