magma

Volcanologists said the formation of a lava lake is obvious proof of the rise of magma to the surface.

UPDATE: April 14. 10:34 a.m. : Vulcanologists from OVSICORI and the National Seismological Network reported two strong eruptions at 7:39 a.m. and 7:57 a.m. on Friday.

Vulcanologists say the increase in the emanation of gases, vapor and water from the Poás crater is caused by a volume of fresh magma from deeper levels that is pushing up toward the surface.

Weather conditions have prevented OVSICORI staff from approaching or conducting flyovers with a drone over the crater to measure the depth of the magma body.
