The last noticeable activity came in 1996, and since then Irazu has been a quiet giant. Located less than sixty miles from the capital of San Jose, the Irazu Volcano makes for a perfect day trip with so much to see! Irazú volcano is located in the Cordillera Central close to the city of Cartago, Costa Rica. The summit of Volcán Irazú is near tree-line, and the wind and volcanic activity conspire to give the effect of a moonscape. It is the highest active volcano in Costa Rica. Irazu is the highest volcano in Costa Rica. The eruption spread material over the northwest side of the volcano and later caused avalanches in the Río Sucio. Irazu last erupted during President John F. Kennedy's visit in1963 spreading ash from Costa Rica to Nicaragua. This park protects colossal Irazu, which, at 3,432 meters above sea level, is the tallest volcano in Costa Rica. Irazú Volcano National Park was created by Law No. The Iztarú tribe, who lived on the slopes of the volcano, knew it as 'Irazu' meaning ‘thundering mountain’; a fitting name for the volcano that has been erupting for the last 500 years. 26945-MINAE of August 22nd 1988, for having a current area of 2000 ha. It is worth mentioning that this activity was documented by Diego de la Haya, for this reason, one of its craters bears his name. From the summit it may be possible to see both the Atlantic and Pacific Oceans. In 1963, Irazú Volcano ended a 20 year silent abruptly on the same day that United States President John F. Kennedy visited. A major eruption of the Irazu Volcano in 1723 completely destroyed the capital at the time and the current Costa Rican capital of San Jose, was completely covered in heavy soot and ash after a 1993 eruption. ... That eruption had a maximum Volcanic Explosivity Index of 3. 1917 of July 30, 1955, published in Official newspaper La Gaceta 175 of August 9 of that year. 1994 Eruption A small phreatic eruption occurred at Irazu volcano on 8th December 1994 fumarole on the upper NW-flank. The 1963–65 eruption of Irazú, like all others of this volcano during the historic period, produced only ash and other fragmental ejecta without lava. The active volcano has a long history of eruptions. Photo courtesy of NOAA'S National Geophysical Data Center. Irazú Volcano Activity. Historically, the Irazú volcano in 1723 was its first major recorded eruption and destroyed the city of Cartago when it was the capital of Costa Rica, but the ash also covered much of San José. Irazú, one of Costa Rica's most active volcanoes, rises immediately E of the capital city of San José. This protected area’s many geological features include the Hermosa Beach, Principal and Diego de la Haya craters, as well as the Sapper formation—the highest point in the massif, from which both Caribbean and Reaching upward of 11,260 ft (3,432 m), Irazu is the tallest volcano in Costa Rica. Later the park was expanded by Executive Decree No. The initial outbreak on March 13, 1963 started with a series of great explosions that hurled out much ash, blocks, and bombs, but the activity soon settled down to alternating periods of explosive cruptions and quiet emission of steam. This view taken in early 1964 shows a dense cloud erupting from the crater. The next eruption can’t be predicted with much accuracy, but currently the only activity in the crater is from fumaroles releasing toxic steam. The massive volcano covers an area of 500 km2 and is vegetated to within a few hundred meters of its broad flat-topped summit crater complex. The most recent eruption was in 1994, but it could become active again at any time. The eruption decimated crops in the area but left the soil enriched for decades to come. This massive volcano covers an area of 500 km 2 (193 mi 3 ) and is vegetated to within a few hundred meters of its broad flat-topped summit crater complex. Irazú is one of Costa Rica's most active volcanoes, rising immediately E of the capital city of San José. Irazú’s last big explosion in 1994 was a phreatic eruption, an explosion of steam, rocks and volcanic bombs that occurs when water is heated by magma. The volcano actually remained active for two more years after this date, spewing lava in a powerful display. Photograph Credit: Howell Williams. Irazú.
