Volcano Hazard level: Low ?

Volcanic eruptions occur when molten rock (magma), gases, and volcanic debris are expelled from a volcano, resulting from pressure buildup beneath the Earth's surface. Eruptions can produce multiple hazards including lava flows, pyroclastic flows, ashfall, lahars (volcanic mudflows), and toxic gases. The hazard severity depends on the volcano's explosivity index, eruption style, proximity, and the specific volcanic phenomena produced.

In the area you have selected (Costa Rica) volcanic hazard is classified as low according to the information that is currently available. This means that the selected area is located at less than 50 km from a volcano for which a potentially damaging eruption has been recorded in the past, but over 10,000 years ago. However, the potential for future damaging eruptions cannot be ruled out. Based on this information, risk studies and the impact of volcanic eruption may be considered in different phases of the project, in particular during project design, implementation and maintenance. Further detailed information should be obtained to adequately account for the level of hazard.
