How come Turrialba is the most dangerous volcano in Costa Rica?

Intermittent eruptions, sometimes violent, in recent months have put Volcano Turrialba in focus.

Situated in Cartago Province, some 36 kilometers northeast of the capital city San Jose, Turrialba is ranked as the second largest volcano in the country.

A volcanologist who has studied Turrialba for years tells Xinhua it is the most dangerous one out of the 200 or so volcanoes in this Caribbean country.

“We currently have at least seven active (volcanoes in Costa Rica), and the most dangerous is the Turrialba Volcano. As to Turrialba, it is an explosive volcano. Its ash strip extends to the Central Valley, where we have the largest population.”

According to geological statistics, this hot pot started to lose temper at least 10,000 years ago, and the first major eruption was recorded 4,000 years ago.

“It still had many small eruptions, and the last ones, apart from the others, were (recorded) in between 1864 and 1866. For two years the ash (continuously) emitted. People could even collect sacks of sand as it was popularly called. So much ash fell down.”

Ash could suffocate, burn and kill, not only crops and plants, but human being and animals.

“We are talking about ash reaching more than 100 kilometers away. This can still occur nowadays with Turrialba. Major eruptions will even affect the coastal sites, something that one can’t believe will happen in Costa Rica.”
