Vocán Poás puts on a great show for the Web camera monitor

As the Costa Rican national soccer team took the field against Italy Friday, Volcán Poás emitted an eruption that flew 200 meters into the air. The eruption, called the second biggest this month, was caught on the Web camera position at the volcano crater.

There is no scientific evidence that the cheers of Tico soccer fans set off the volcano, but in the commotion following the sensational 1-0 victory against the Italian team, the event was largely unnoticed. The Observatorio Vulcanológico y Sismológico de Costa Rica at Universidad Nacional has issued a report with photos.

The largest eruption this month was June 1 but at night. So there is no visual evidence, the Observatorio said. Researchers found evidence the following morning. The Friday eruption took place at 10:08 a.m., the report said.

The volcano is a popular tourist site, and Poås has been emitting eruptions repeatedly, much to the delight of tour operators.

The Observatorio said that a whole litany of gases are set free when the volcano behaves like this although the majority is water vapor, carbon dioxide and sulfur dioxide.  These eruptions can come without any notice, presenting a danger to researchers who might be in the floor of the crater. University experts frequently are there. A team was there the previous Wednesday.

Most of the eruptions have stayed within the crater, and the tourist overlook is well away from danger. The volcano has been behaving like this since 2005 and it is expected to continue, the Observatorio report said.

The eruption sequence covers 30 seconds, the Observatorio reported. The camera was a gift from the U.S. Office of International Development.
