Population distribution:
roughly half of the nation's population resides in urban areas; the capital of San Jose is the largest city and home to approximately one-fifth of the population

Natural hazards:
occasional earthquakes, hurricanes along Atlantic coast; frequent flooding of lowlands at onset of rainy season and landslides; active volcanoes

volcanism: Arenal (1,670 m), which erupted in 2010, is the most active volcano in Costa Rica; a 1968 eruption destroyed the town of Tabacon; Irazu (3,432 m), 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

Environment - international agreements:
party to: Biodiversity, Climate Change, Climate Change-Kyoto Protocol, Desertification, Endangered Species, Environmental Modification, Hazardous Wastes, Law of the Sea, Marine Dumping, Ozone Layer Protection, Wetlands, Whaling
signed, but not ratified: Marine Life Conservation

Geography - note:
four volcanoes, two of them active, rise near the capital of San Jose in the center of the country; one of the volcanoes, Irazu, erupted destructively in 1963-65
