“(…) undisputed evidence of the presence of fresh chunks of lava, which were ejected in incandescent form and in a molten state [during previous eruptions],” said the RSN.

According to information from the RSN, this material certainly indicates the presence of fresh material a few hundred meters from the surface under the active crater.  The experts believe the magmatic levels of the colossus are rising, at an alarming rate.

“These fragments of lava today represent the youngest volcanic rocks Costa Rica, only 5 days old,” reports the RSN through social networks.

Volcanologists suggest that the composition of the material is of a basaltic andesite, which has minerals such as plagioclase, olivine and pyrogens. This type of lava is normal within the volcanism of the active volcanic mountain ranges of Costa Rica.
