10:30 p.m. Ash emissions continue on the Turrialba volcano.
As that observed at this time through the remote surveillance camera of OVSICORI, installed at the top of the volcano. Activity remains constant, with a tremor signal high, with little variation since 7:20, and pulse generating higher ash exits, the last 10 minutes in the form of seismic signals, as indicated by the installed instrumentation the RSN and OVSICORI.
The emanation of ash persists, the column reaches approximately 300 m above the crater and is dispersed in the West-Northwest direction.
Winds can always raise more than ash and transport them to the top of the Central Valley and northern Heredia.
The CNE and the scientific and technical organizations are constantly monitored.
