Moment magnitude scale

A large-scale earthquake registered at a magnitude of 7.0, occurred in Haiti on January 12, 2010, on the West Indian island of Hispaniola. The shock compromised the countries of Haiti and the Dominican Republic. It was estimated that more than a third of the population of the country was affected by the earthquake, along with many homes destroyed beyond repair (Pallardy). Similarly, in Nepal, nearly nine thousand people died from the two earthquakes in April and May 2015, and the remote villages had many homes destroyed from the quakes (Bhandari and Najar). Around noon local time, the first major earthquake hit Nepal, which registered a moment magnitude of 7.8 (Rafferty). Both countries, Haiti and Nepal were in dire need of aid relief. Richard…

In this week’s reflection assignment the required reading was over restoring rifle and shotgun barrels. The article explained the processes and procedures for lapping shotgun and rifle barrels.as well as altering shotgun barrels. And soldering, brazing, and welding In the required reading the author explained the differences between lapping the different lapping compounds. And explained the applications for the different compounds. The article also gave an overview of the tool involved in the…

Bak argues that mass extinction is an inherent property of a species, and is not the result of external factors such as a large natural disaster, since they are complex systems. Punctuated equilibrium is a manifestation of the self-organized critical state in biological evolution. For long periods of time, it appears that evolution is not occurring, simply because the system is in the critical state. This intermittent stage is dominated by the Red Queen Effect, where it takes all of the…

The earthquake struck at a shallow depth of 5kms and was measured at 6.1 on the Richter scale, this disaster affected the majority of the southern island and the base of the northern island of New Zealand, showing the dramatic proportion of the damage that occurred. The city of Christchurch however was the hardest hit and the surrounding area which covered 1,426 square kilometres. Approximately 100,000 buildings were damaged from the earthquake and roughly 10,000 buildings had to be knocked…

1.1 Introduction to Landslide A landslide is a geological phenomenon, which includes a wide range of ground movements, such as deep or shallow failure slopes and rock falls. See figure 1.1. 1.1.1 Factors influence Landslides Landslides occur when the stability of the slope turns from the stable state to unstable state. Most of the Landslides usually cause depend on two main factors: (i) Natural Factors and (ii) Anthropogenic Factors. (USSG, 2004) (i) Natural Factors (a) Geological…

have never thought of becoming a seismologist, it something I would want to learn more about. A seismologist studies seismic waves, energy waves caused by rock suddenly breaking apart within the earth or slipping of tectonic plates. There are many ways that scientists are able to study seismic ways and earthquakes. The first way is when seismologist analyze the damaged cause by an earthquake and then study it using a seismograph. The seismograph will tell the scientists the strength and the…

shaking of the ground. However, this just how people see the phenomenon where destruction follows. According to Christopher Scholz and his two colleagues, “The sudden movement of the Earth caused by the abrupt release of accumulated strain along a fault in the interior,” meaning an earthquake is the sudden movement along a fault line, which is where tectonic plates meet. When the plates shift this causes the Earth to shake but when the plates become unrestrained large earthquakes occur. The…

Oklahoma County has not been really active. Before the earthquake swarm started in the Jones area, there was only 7 earthquakes per year in Oklahoma County. But, since the Jones swarm started, there are a few hundred earthquakes per year. And, since January 2009, eastern Oklahoma County has been shaking off and on. Most of the quakes are around Jones, Oklahoma. The Oklahoma Geological Survey was interested in the 10,000 percent increase in seismic activity. Austin Holland, a seismologist for the…

Many of those who live in central Italy near L’Aquila were greatly impacted by the 6.3 magnitude earthquake that shook the entire town and surrounding areas in 2009. After this, many of the residents in these areas took comfort in the idea that it happened once, and it wouldn 't happen again. But when houses began to shake at 3:36 A.M. on August 24th, 2016 disaster struck once again. Though this earthquake was not as large as the previous one, the magnitude 6.2 was followed by almost 200…

The design of this report is to show the is to show the written report of an earthquake occurring either on the San Andreas Fault Line or the Hayward Fault Line. Designing bridges and seeing if the bridge that was built to survive an earthquake with the magnitude of 5.0-8.0 for Hayward and for San Andreas 5.0-9.0 the power of these earthquakes have the power to destroy lots of things at once. Some earthquakes are not noticeable but it 's the fact that earthquakes are so powerful that it can go…
