Natural hazards:
occasional earthquakes, hurricanes along Atlantic coast; frequent flooding of lowlands at onset of rainy season and landslides; active volcanoes
volcanism: Arenal (elev. 1,670 m, 5,479 ft), which erupted in 2010, is the most active volcano in Costa Rica; a 1968 eruption destroyed the town of Tabacon; Irazu (elev. 3,432 m, 11,260 ft), situated just east of San Jose, has the potential to spew ash over the capital city as it did between 1963 and 1965; other historically active volcanoes include Miravalles, Poas, Rincon de la Vieja, and Turrialba
Environment - current issues:
deforestation and land use change, largely a result of the clearing of land for cattle ranching and agriculture; soil erosion; coastal marine pollution; fisheries protection; solid waste management; air pollution
