Volcano Puu Oo Olivine Ash Raw Minerals Lapilli Pumice Lava Bombs Stones Rocks Collecting

Volcanic Ash sample Raw Minerals Lapilli Pumice Lava Bombs Stones Rocks for Collection.
Rare collection of super green volcanic olivine sand ash from Mount Pu'u 'Ō'ō Mahana cinder cone Volcano eruption 10,000 BC, collected from the Mahana Beach.
The sample is almost entirely translucent green volcanic Olivine (Peridot) volcanic coarse glass fragments. Cool stuff and known from only 4 localities in the word.

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.

Pu'u 'Ō'ō (often written Puu Oo) is a volcanic cone in the eastern fracture zone of the volcano Kīlauea of ​​the Hawaiian Islands. Pu'u 'Ō'ō explodes continuously since January 3, 1983, making it the longest eruption of this area of ​​the last two centuries.
The hill was initially nicknamed "Pu'u O" by volcanologists, because its position, when it was marked on a map of the area, coincided with an "o". Later, the elders of the village of Kalapana were asked to name the new hill, and chose Pu'u'Ō'ō.
Pu'u 'Ō'ō eruption began when fissures split the ground in the rainforest of the eastern fracture. In June 1983, activity was strengthened and localized in the mouth of the Pu'u'Ō'ō. Over the next three years, 44 eruptive episodes with lava fountains up to 460 meters high have interrupted traffic at various points along eastern Hawaii. The fallout from ash and spray from the imposing lava fountains built a 255 meter high cone.
In July 1986, the pipeline that supplied the magma to Pu'u 'Ō'ō broke off and the eruption abruptly shifted 3 kilometers to form the Kūpa'ianah vent. With the new vent, a new type of eruption arrived: the continuous, silent pouring of a lava lake was replaced by the high episodic fountain. After a few weeks, a roof formed over the main lava flow channel, created a lava tube. This allowed the lava to retain the heat remaining fluid for long distances until reaching the ocean 12 kilometers from the mouth. The lava flow ceased when the lava tube system went out.
In 1990, the eruption entered its most destructive phase when the flows turned eastward and totally destroyed a couple of villages, bays and surrounding beaches, covering them completely with lava. Over 100 houses were destroyed by the ever-expanding flow over a nine month period. The volume of lava erupted by Kūpa'ianah decreased steadily until 1991, and at the beginning of 1992 it had definitively ceased. The eruption then returned to Pu'u'Ō'ō, until 1997, with a short fissure eruption in the crater of Nāpau, southwest of Pu'u 'Ō'ō.
On the evening of January 29, 1997, a series of earthquakes struck the eastern part of Kīlauea. When the magma found a new path on the surface, the ground cracked in the nearby crater of Nana and the lava fountains illuminated the night sky. However, activity in this area was short-lived and the center of activity soon returned to Pu'u'Ō'ō.
In January 2005, 2.7 cubic kilometers of magma covered an area of ​​over 117 square kilometers and thus added 0.93 square kilometers of land to the southeastern coast of Hawaii. So far, the eruption has destroyed 189 buildings and 14 kilometers of highways and many ancient Hawaiian sites. The coastal highway has been closed since 1987, as it has been buried under the lava up to 35 meters thick.
In 2008 the cone of Pu'u'Ō'ō was in the 25th year and 57th eruptive episode. This was the largest lava volume of the last five centuries to erupt from the eastern fracture zone of the volcano. New activities followed in the following years: that of 2011 eventually destroyed all the remaining houses, while on 27 June 2014, new mouths opened on the northeastern flank of the cone of Pu'u'Ō'ō. Still a collapse of the Pu'u 'Ō'ō crater took place on April 30, 2018 with the creation in May of an ash plume. The lava flowed underground until about 10 miles away. Residents located on the southeast coast of the island were asked to evacuate. On May 3, 2018, the Pacific tsunami alert center reported a magnitude 4.6 earthquake from the south flank of the volcano. The USGS reported that there were about 70 earthquakes of magnitude 2.5 or stronger in just 2 days.
The current state of the Pu'u 'O'o outlet can be checked on the Hawaiian Volcano Observatory website.
