Volcano Cerro Azul Ash Raw Minerals Lapilli Pumice Lava Bombs Stones Rocks Collecting

Volcanic Ash sample Raw Minerals Lapilli Pumice Lava Bombs Stones Rocks for Collection.
Rare specimen Volcanic Sand erupted from the Cerro Azu Volcan during the eruption of 9 August 1967, taken from Quizapu Crater. Extremely fine grained.

Available on our website, besides ashes, pumice and bombs, also various volcanic rocks, such as Apache Teardrops, sulfur, obsidian, tuff, crystal chalk, etc.

Volcanic ash consists of small tephra, which are bits of pulverized rock and glass created by volcanic eruptions, less than 2 millimetres (0.1 inch) in diameter . Ash is created when the usually violent nature of an eruption involving steam results in the magma and solid rock surrounding the vent being torn into particles of clay to sand size.
Every ash samples is labelled and bagged in a vial with cap (mm 44 x 10), so thay can easily be removed if required for study under a microscope.
As with all volcanic ash, the material should be handled with care and not inhaled.

Cerro Azul (Spanish pronunciation: [sero asul], blue hill in Spanish), sometimes referred to as Quizapu, is an active stratovolcano in the Maule Region of central Chile, immediately south of Descabezado Grande. Part of the South Volcanic, its summit is 3,788 meters (12,428 ft) above sea level, and is capped by a summit crater that is 500 meters (1,600 ft) wide and opens to the north. Beneath the summit, the volcano features numerous scoria cones and flank vents.
Cerro Azul is responsible for several of South America's recorded eruptions, in 1846 and 1932. In 1846, an effusive eruption formed at the site of the present-day Quizapu crater on the northern flank of Cerro Azul and lava flowing down the sides of the volcano, creating a lava field 8-9 square kilometers (3-3.5 square miles) in area. Phreatic and Strombolian volcanism between 1907 and 1932 excavated this crater. In 1932, one of the largest explosive eruptions of the 20th century occurred at Quizapu Crater and felt 9.5 cubic kilometers (2.3 cu mi) of ash into the atmosphere. The volcano's most recent eruption was in 1967.
The South Volcanic Zone has a long history of eruptions and poses a threat to the surrounding region. Any volcanic hazard-ranging from minor ashfalls to pyroclastic flows-could pose a significant risk to humans and wildlife. Despite its inactivity, Cerro Azul could again produce a major eruption; if this were to happen, relief efforts would probably be quickly organized. Teams such as the Volcano Disaster Assistance Program (VDAP) are prepared to effectively evacuate, assist, and rescue people threatened by volcanic eruptions.
