Here Are The Top Fun & Interesting Facts About Arenal Volcano:
#1 Arenal Volcano, also referred as “The Canaste Volcano” or “Pan de Azúcar,” is a remarkable volcano that is the youngest of all of the Costa Rica volcanoes.
#2 The volcano is located in the northern part of Costa Rica, in Arenal Volcano National Park, a 29,960-acre national park.
#3 It lies along a volcanic chain which has migrated to the north-west from the late-Pleistocene. Los Perdidos lava (Pleistocene volcanoes are volcanoes which were active during the Pleistocene epoch – from 2.5 million to 11,700 years ago) domes through the Pleistocene-to-Holocene Chato volcano.
#4 The Arenal volcano measures 5,358 feet (1,633 meters) high. It is conically shaped with a crater 460 feet (140 meters) in diameter.
#5 Inside this national park, you may also visit – the Lake Arenal Dam, Lake Arenal, and an inactive volcano called Mount Chato (better known as Cerro Chato). Scientists believed that Mount Chato first erupted 38,000 years ago during the Pleistocene period.
#6 There is also plenty of wildlife in the park. For instance, there are at least 135 species of reptiles, such as – eyelash pit vipers, fer-de-lance (a highly venomous pit viper species), iguanas, and boa constrictors.
#7 In addition, there are over 130 species of mammals, such as – howler monkeys, white-faced monkeys, three-toed sloths, spider monkeys, raccoons, coatis, jaguar, tolomuco, and ocelots.
#8 The volcano towers over the surrounding landscape, which is surrounded by plantations producing one of the best coffee in the world. Also, there is evidence of human life in the surrounding area dating all the way back to 4000 B.C.
#9 The earliest estimated eruption of the volcano occurred about 7,000 years ago. It was dormant for centuries and exhibited a single crater at its summit, with occasional fumaroles (an opening in a planet’s crust) activity, covered by dense vegetation.
Note – a volcano is considered active only if it has erupted in the last 10,000 years, according to the Smithsonian Global Volcanism Program.
#10 On Monday, July 29, 1968, at 7:30 AM, this volcano erupted and destroyed the small town of Tabacón. This day will always be remembered in Costa Rica for the death of 87 people.
#11 Interestingly, this volcano was thought to be extinct prior to the eruptions of 1968 (the USGS defines a dormant volcano as any volcano which is not showing any signs of unrest but could become active again).
#12 Moreover, the local ranchers and farmers who worked the grounds near its base referred to the volcano as the mountain – Arenal Mountain (Cerro Arenal).
#13 Between 1968 and 2010, the volcano was active – it spewed smoke, hot rocks, ash, and lava from its top on a regular basis.
#14 During this time, lava could be seen streaming down the sides of the Arenal volcano, making it a great attraction for tourists.
#15 Its rock is mainly basaltic andesite and it erupted in the form of Vulcanian and Strombolian tephra, slow-moving lava flows, and pyroclastic flows.
#16 Since 2010, it has been dormant again.
La Fortuna de San Carlos
#17 It is the name of the nearest town to the Arenal Volcano, about 8 km distance. This town is located in Alajuela province and connects the volcano area with the northern lowlands of the country and the forests of Santa Elena and Monteverde.
#18 Beside the volcano, La Fortuna de San Carlos has other amazing tourist attractions, including a breathtakingly 70-meter high waterfall.
The Arenal Observatory Lodge
#19 It is located southwest of La Fortuna de San Carlos, at the foot of the volcano.
#20 This is the only accommodation in this National Park. It offers one of the best places to observe the Arenal volcano.
Other Volcanoes That Were Thought To Be ”Sleeping”
Kadovar Volcano, Papua New Guinea
It forms the tiny 2 km wide Kadovar Island, one of the Schouten Islands. The volcano erupted in spectacular fashion on January 5, 2018, spewing lava for the 1st time in known history and sending an ash cloud more than 2.1 kilometers above sea level.
As of March 20, 2018, there are a total of 557 affected populations from the villages of Taragauo, Dong Sarakbano, Manot, Niukatnam and Rumgio thanks to Kadocar eruption.
Mount Tongariro, New Zealand
This volcano is located 12 miles (20 kilometers) to the southwest of Lake Taupo (surface area of 616 square kilometers) and is the northernmost of the 3 active volcanoes which dominate the landscape of the central North Island.
On August 6, 2012, Mount Tongariro erupted just before midnight in the 1st important activity at the site since 1897.
Mount Agung, Bali
Gunung Agung, also known as Mount Agung, is a volcano in Bali, Indonesia, southeast of Mt Batur volcano (this volcano is marked by a collapsed top, called a caldera), also in Bali.
In 2017, Mount Agung has started spewing magma many miles high above the island of Bali for the 1st time in more than 50 years. The 2017 eruption caused over 40,000 people to be evacuated from 22 villages around the volcano.
It has erupted again in February 2018, just several days after the alert status was lowered in the area.
