When Volcán Poás cleared its throat two minutes before 8 a.m. Monday, ash from the eruption showered the pedestrian overlook and the visitor center, said the Observatorio Vulcanológico y Sismológico.
The eruption lasted just a minute and a half, but the column of steam, water, mud and ash climbed to 250 meters, said the Observatorio. That’s over 800 feet. That’s the reason why the volcano park was closed to visitors for awhile.
Poás began the current cycle of eruptions in 2006, the Observatorio staff noted. Since 2009, the eruptions have become stronger and reached higher levels.
There was a slowdown with the volcano eruptions in August, September and this month, the volcano staffers noted, calling the ones that took place more energetic.
The activities at the volcano suggest that there is a body of magma that is not very deep below the lake, the Observatorio said.
