Krakatau, West of Java
I. Introduction
Krakatau is a former stratovolcano that is located within the Sunda Strait between Java and Sumatra. The most popular and logical theory for the origin of its name is that it was adapted from the sanskrit word “Karkata”, justification being that Rakata is cited as meaning crab in the older Javanese language (Wilson, 1999). The origin of this volcano is perhaps first noted in the Javanese Book of Kings in 416 A.D. as a “thundering sound” in Kapi, a westward province of Java. Despite this reference, no geologic evidence of an eruption has been reported of that time. It is believed that during this time period the eruption left the three islands that we know of today. This paper will explore the legacy of …show more content…

By 1930 it crested anew producing flows faster than the waves could erode them. It currently grows at approximately 6.8 meters per year and is active, alternating between quiet periods and strombolian eruptions (Shoeman). It is located between the two former volcanoes Danan and Perbuwatan
X. Anak Krakatau’s Eruptions
In terms of chemical composition, it has been noticed that the flows of Anak Krakatau are similar to those in Hawaii. There is a presence of basalt as well as the old rhyolite of Krakatau, making Anak Krakatau a chemically complex volcano (Shoemaker). As denoted in the geochemical section of this paper, Anak Krakatau is next in a series of magma types, or is slightly differentiated, and is a significantly active volcano with enumerative degassing events. Eruptions include frequent pyroclastic flows
XI. Conclusions
Overall, Krakatau was one of the most infamous and devastating volcanic eruptions mankind has been around to witness. Ranking a VEI of 6 and a death toll of over 36,000 people, the impacts of this hydrovolcanic eruption were astounding. In light of this, more information was recorded and spread than with any preceding

    The ginormous volcano at Akrotiri on the island of Thera during the Bronze Age was devastating, and is speculated to be related to the fall of the Minoan civilization. Starting in 1867, archeologists discovered pottery, a buried city and frescoes. These discoveries are the most significant as the pottery and the buried city helped historians learn about the art, trade and societal aspects of Akrotiri, and the frescoes found revealed more information about Akrotiri’s art and religion.

    While Kamiak butte is primarily made of quartzite, it is surrounded by a thick layer of basalt. Basalt is an intrusive igneous rock. The basalt at Kamiak Butte is 6 to 17 million years old.1 It is dense and dark in color- grays or black hues.2 Through research I learned that the basalt at Kamiak Butte was formed on a rift zone. Lava flowed from the rift zone into the area. In turn flattening out what were the preexisti...

There are many sections in this article that discuss the methods used to determine the closet possible dates and the sequence in which they follow. There are also sections in this article which discuss methods used for the evidence of impact, eruption and how reading the environmental changes can help paleontologists determine conclusions and narrow the perspectives of paleontologists (scientists) and popular culture as a whole.

  • The 1815 Eruption of Mount Tambora

    2292 Words  | 5 Pages

    Mount Tambora, located on the Island of Sumbawa, Indonesia is classified as a Stratovolcano. Also known as a composite volcano, Tambora is a tall conical volcano (cone like structure) where layers of the walls are built by hardened lava and volcanic ash. The term composite is used to describe the volcano due to the composite layered structure built from sequential outpourings of eruptive materials1. Among the most common types of volcanoes, Tambora also shares its destructive prowess with best-known volcanoes such as Krakota (1883) and Vesuvius (79 A.D). The Island of Sumbawa is located in the middle of the Lesser Sunda Islands chain (a group of islands in the southern Maritime Southeast Asia) and is in the province of West Nusa Tenggara3. A map of Mount Tambora is shown in Figure 1 to provide a better perspective of its location. Interestingly enough, Tambora forms its own peninsula on Sumbawa, known as the Sanggar Peninsula. In April of 1815, after years of dormancy, Mount Tambora erupted with great intensity, approximately 7 on the volcanic explosivity index, which is shown in Figure 2. It has been estimated that the eject volume of Tambora was 160 cubic kilometres, which represents the largest volcanic eruption in recorded history. The death toll has been projected to be at least 71,000 people, of who over 15% were killed directly from the eruption1. The remaining 75% have been thought to succumb to starvation and disease, as the eruptive fallout decimated the agricultural industry in the region. Following the eruption, a volcanic winter ensued. As sun become less abundant due to clouds of ash, crops and livestock perished. Please note that all definitions appearing in the footnotes are either taken from already referenced so...

  • Kohala Volcano Essay

    1084 Words  | 3 Pages

    Over the centuries, the making of the Big Island as we know it today eventually entailed the growth and conjoining of six separate volcanoes, building all the way up from the seafloor, some 18,000 feet below the ocean’s surface. These volcanoes, from northwest to southeast, are named Mahukona, Kohala, Mauna Kea, Hualalai, Mauna Loa and Kilauea, and become younger as one moves north to south. Mahukona Volcano, just off the Big Island’s northwest coast, was the first volcano to start forming. Now submerged beneath the surface of the ocean because it is sinking into the Earth’s crust under its own vast weight, Mahukona is no longer visible. As the Pacific Plate slowly continued moving northwestward over the hotspot, the location of the rising magma moved relatively southeastward, and through time the rest of the Big Island volcanoes formed along that path.After Mahukona, Kohala Volcano, the precursor to today’s Kohala Mountain, erupted next. As Kohala Volcano emerged from the sea and joined with Mahukona, a much larger Big

    The earliest outcropping volcanic deposits date back to about 25,000 years ago. The lavas observed at a -1125 m bore-hole are about 0,3-0,5 million years old. It is known for the first eruption of which an eyewitness account is preserved, in 79 AD. Geologically, Vesuvio is unique for its unusual versatility. Its activity ranging from Hawaiian-style release of liquid lava, fountaining and lava lakes, over Strombolian and Vulcanian activity to violently explosive, plinian events that produce pyroclastic flows and surges.
