Rincon de la Vieja Volcano
Rincón de la Vieja Volcano is 25 km away from Liberia, located in the province of Guanacaste. Rincón de la Vieja elevation is 1916 meters above sea level, It has many peaks and craters, among these Santa Maria peak is the highest elevation of the volcano, Von Seeback peak is at 1895 meters above sea level. Remaining crates are in an degradation stage. Rincon de la Vieja national park covers 142 square kilometers of terrain and it encompasses Rincon de La vieja and Santa Maria Volcano.
The first recorded eruption of the volcano took place in 1765, Before that, the actual shape of the volcano points that once occurred a big eruption thousand of years ago. The last recent eruption was in 1998, the most recent eruptions have had place in the Von Seeback crater, but these eruptions are limited only to the crater. The active crater is a lagoon of hot and acid water.
Rincón de la Vieja is one of seven active Costa Rican among the Miravalles volcano, Arenal, Turrialba, Irazú , Poás and Orosí.
Guanacaste Cordillera Main Volcanoes:
Orosi Volcano, Cacao Volcano, Rincon de la Vieja Volcano, Santa María Volcano,
Miravalles Volcano, Arenal Volcano
and Chato Volcano
Miravalles Volcano is a located in Costa Rica at the Guanacaste province, 21 Kilometers away from Liberia. At its peak can be detected up to 6 volcanic craters, with 5 being aligned with NE-SE direction, the highest peak is 2028 meters above sea level. The boiler was formed as a result of several eruptions of pyroclastic few hundred of years ago. Miravalles Volano has an elevation on 2028 metres and its last explosion was on 1946.
On Miravalles, the Instituto Costarricense de Electricidad developed the Miravalles Geothermal Project, which produces electricity based on steem heat generated by the volcano.
The Miravalles volcano is sourrounded by the Miravalles Forest Reserve, a terrain of 108.5 square kilometers of protected area.
The Arenal volcano is perfectly conically shaped with a crater of 140 meters. The Arenal is geologically considered a young volcano. The local residents have also known it as "Arenal Peak" , "Pan de Azúcar", "The Canaste Volcano", "Río Frío Volcano" or "The Guatusos Peak". The volcano height is a 1,633 meters (5,300 feet)
The volcano was asleep for hundreds of years and exhibited a single crater at its summit, with minor fumaroles activity, covered by dense vegetation. In 1968 it had an eruption and destroyed the small town of Tabacón. Due to the eruption three more craters were created on the western flanks but only one of them exists at today's date.
Arenal is considered Costa Rica's most active volcano and has been studied by seismologists for many years and although the activity nowadays is less damaging you can still see daily ash columns, underground rumbling, glowing orange lava flows and sudden explosions. With its perfect conical shape it allows breathtaking views of volcanic action in the summit. Almost every night the crater offers a spectacle of lights with its explosive eruptions.
The Arenal Volcano area is an important watershed for the Arenal Lake Reservoir. Water from here is used for hydroelectric power, with the purpose of satisfying the electricity demand of the inter-connected national system and the Guanacaste irrigation projects.
