EES: 1030: 0B06 12/6/17 Toba, the Deadliest Volcano Eruption Around 74,000 years ago during the Quaternary period, the supervolcano known as, Toba, erupted in Northern Sumatra, Indonesia. Toba is thought to be one of the largest known eruptions the Earth has ever seen. And certainly the largest to erupt during the Quaternary period. Out of the three periods that make up the Cenozoic Era, the Quaternary period is the current and most recent of the three. The eruption of the Toba volcano did not…

flow on Newtonian fluids on plate, cones and disks. Hari R [30] investigated the chemical and radiation effects on MHD casson fluid flow past an oscillating vertical plate embedded in porous medium. Subbaiah Naidu [70] studied the effect of Hall current on free convective flow of stratified fluid over an infinite vertical porous plate. Venkateswarlu M et.al [74] studied the effects of chemical reaction and heat generation on MHD boundary layer flow of a moving vertical plate with suction and…

1. Introduction The Brent field is an oil field located in the East Shetland Basin. This oil field was the first discovery in the northern part of the North Sea. It is located 186 kilometres north-east of Lerwick, Shetland Islands, Scotland at the water depth of 140 metres (460ft). (Figure 1) The field lies entirely within United Kingdom (UK) licence Block 211/29 at latitude 61°N and longitude 2°E. The Brent field is one of the biggest hydrocarbon accumulations in the United Kingdom area.…

A VOLCANO TRAGEDY January 15 , 2004 was the tragic day that a volcano had erupted. It all happened so fast like in a blink of an eye everything was so dark and magma was gushing out like a gusher candy. We realized that we where in the ring of fire , after the tragedy had passed. Before all that happened me and my family decided to head for safety in a gym where thousands of people were panicking trying to find out…

1. Mount Fuji: Mount Fuji is the highest mountain in Japan, soaring to well over 12,000 ft! It is also an active volcano, and considered to be one part of Japan’s trilogy of Holy Mountains. It is indeed considered a sacred spot, and those who brave the strenuous climb to the summit are sure to come across many make-shift shrines that have been erected along the way. Be sure to visit Hakone, a resort located at the mountain’s base that offers road-weary hikers the opportunity to take a luxurious…

The Santa Cruz earthquake happened on October 17, 1989, in San Francisco Bay Area and magnitude was 6.9. 67 people were killed, and over 5 billion damages followed the earthquake. (History.com Staff, 2009) Community and people think this earthquake occurred in San Francisco area. However, there were other affected cities such as Los Gatos, Watsonville, and Santa Cruz, etc. In consequence of location, scientists, geologists called this earthquake differently such as Loma Prieta earthquake, San…

Mauna Loa Volcano What volcano is referred to as the largest of the world? What is one of the most active volcanoes in the world? Thats right the Mauna Loa. The Mauna Loa rises 13,680 feet above sea level and in meters it is 4169.664 above sea level. The location of the Mauna Loa is on The Big Island, in Hawaii. It’s geographical coordinates are 19.4721 degrees north and 155.592 degrees west. The Mauna Loa volcanic activity started 700,000 to 1,000,000 years ago, around when it first…

The location I chose for this assignment is my home county, San Diego. San Diego is known for having the best weather in the United States, which it can attribute to its geology. San Diego is also well known for consistent droughts; however, its current unique geography is a result of ancient rivers and seas depositing Cretaceous and Tertiary sedimentary rocks. As a result of these ancient rivers, “San Diego County can be divided between three distinct geomorphic regions: the Coastal Plain…

The second most abundant element in the Earth’s crust other than oxygen is silicon which if by mass is around 25.7g or 23%. However in nature, silicon never exist as a free or pure element but instead it mostly combines with the most abundant element in the Earth’s crust, oxygen, hence producing silica (SiO₂) or silicate minerals. The most prominent charge of Si in the crust is +4 rather than +2 which involve a silicon atom to bond in a tetrahedral manner with 4 other oxygen atoms giving rise to…

On January 17th 1994, at 4:31am, a magnitude 6.7 earthquake struck the San Fernando Valley region of Los Angeles, killing more than 60, injuring more than 9,000, and causing widespread damage (Taylor, 2014). With the vast amount of damage, loss of life, and injuries it is easy to understand how the local and state responders would have quickly been overwhelmed in their response measures. This is the exact sort of emergency that the Stafford Act was developed for. According to (Hunter, 2009),…
