recognize the signs, and better educate themselves. Through grasping how an earthquake occurs, and where they happen in the world can better help people understand earthquakes as a whole. Also, in being mindful on how earthquakes are measured and their magnitude can help someone become better educated on the topic of earthquakes since they could happen at any time. Besides the fact, learning about the causes, foreshocks, mainshocks, and aftershocks are also vital in sensing earthquakes. Not only is it fundamental
This quake was documented on 22 of May 1960 and was a magnitude of 9.2 by the U.S. Geological Survey and was said to be the largest earthquake of the 20th century (Lutgens, Tarbuck, & Tasa, 2015). The earthquake started off of the coast of Chile, and sent the seismic force inward toward the city of Valdivia
evacuation plans, reliable roads in flood situations, shelters or other safe places to stay, access to food, and disclosure of these plans to the public sector. If they had access to better recovery and reconstruction plans, this too would reduce the magnitude of the aftermath. There is no such thing as "zero risk" but we can reduce the loss of life property, and increased poverty but this will require industrial, environmental, economic, legal and political involvement. Disaster management measures varies

Earthquakes: How they happen and what to expect. What is an Earthquake? Have you ever wondered how it starts and what causes it? Many people spend everyday studying this to find answers. In theory scientists do know that an earthquake is the shaking of the ground caused by sudden release of energy inside the earth's crust. This is also known to scientists as the breaking and moving of tectonic plates along a fault line, which than creates seismic waves at the epicenter. The earthquake has
Ever since the catastrophe centered in Northridge, resources have been allotted to prepare people in the event of another situation like the Northridge Earthquake. In elementary school, children are taught how to protect themselves from earthquakes. The main technique used is drop, cover, and hold on. Students were taught to drop under their desk, cover the back of their head and neck area with one of their hands and grab one of the legs of the desk with their other hand. This position was to be
The Day of Tragedies “Would you like to see your new baby sister?” my father said with exhaustion but joy in his voice. As I entered the room, I saw my new sister, Annika Marie Acuna. I already knew her name considering I picked it out from a magazine. My mom handed me Annika having total trust in me to not drop her. But I guess I’m a pro by now since I’m the eldest of two little sisters. Annika was a heavy baby coming in at nine pounds eleven ounces. But all of that was just a flashback to fifteen

It was a strong earthquake that slammed the central area of Taiwan. The earthquake was measured 7.3 on the Richter scale. During the earthquake, the people of the entire island felt the shaking of earth beneath them and the building for a few minutes. In Nanto, the area of the epicenter, almost all of the buildings collapsed. In Taichung, a close metropolis, many
beings experience huge loss to their life and livelihood through earthquakes. Some deadliest earthquakes till the date; • 1556 Shaanxi earthquake: On 23rd January, 1556 at Shaanxi (China) world’s worst quake took around 8 lakh lives with its 8.0Mw (Magnitude) vibration. More than 500 miles area damaged through it. • Great Tangshan earthquake: On1976 July 28, China again experienced another horrific natural disaster of 7.7Mw shake which destroyed a lot of hard earned properties and around 7 lakh innocent
One of the major aftermaths of the Northridge Earthquake of January 17, 1994, was the widespread connection damage that posed a major question regarding the behavior of field-welded, field-bolted moment frame connections, also known as Pre-Northridge connections. Before the Northridge Earthquake, Steel Moment Resisting Frames (SMRFs) were believed to have ductile behavior that would achieve high-cycle fatigue. As a result, fatigue was not considered to be a failure mode for these connections during
Guatemala Guatemala is a small country located in the Americans it's barely the size of Tennessee. Guatemala is bordered by Mexico to the north and west, the Pacific Ocean to the southwest, Belize to the northeast, the Caribbean to the east, Honduras to the east and El Salvador to the southeast .(Guatemala by Kari Schuetz ) Guatemala has comfortable weather neither too hot nor cold. Its seasons tend to be divided into 2 parts the wet season and the dry season. From mid-May to October
earthquake. From reading and looking off the seismograph, we can determine the direction, distance, magnitude and the specific type of earthquake that just happened. Furthermore, the records on the seismograph, based on the motion of the ground is called a seismogram. With our understanding of detecting earthquakes, let’s look at Japan’s Tohoku earthquake. Firstly, it was a megathrust earthquake with a magnitude of 9 that ruptured undersea around 130 kilometers away from Sendai. It was from two plates,
Francisco has the technology and all the measurements are taken to predict an earthquake or any other disaster, some disasters can happen anytime and very suddenly. Such a disaster was the 1985 earthquake, which read a strikingly high 7.2 on the Richter scale. This earthquake, in the highly populated San Francisco might have killed only 63 and injured many more but the economic impacts were great as buildings were destroyed, bridges collapsed and fires blazed through the city destroying anything in
Earthquake is a frequent phenomenon in areas called ‘earthquake zones.’ Earthquake creates numerous kinds of effects such as loss life and damage of property depending upon its magnitude. Earthquake can make damage from small to large impact on communities. As some consequences of the earthquake, there is secondary effects like fire, water supply problem, electricity, transportation, and communication disruption (Gaurav Kaushik, 2013). Manmade infrastructures are playing an important consideration
observing station Agra (27.2o N, 78o E). The details of these earthquakes are mentioned in table 1 which shows the days of occurrence, magnitudes, depths (km), locations (Latitude and Longitude in degrees), radius of influence zone (km) and distances from the Agra station (km). The radius of influence zone is calculated by using the expression R = 100.43M, where M is the magnitude of the earthquake [21]. Although these earthquakes have occurred far away from the observing station Agra, atleast two of them
natural disasters that United States had ever seen at the time. Although the earthquake lasted under a measly minute, it caused significant damage and began various fires. Having started on April 16 at around five in the morning, with an approximate magnitude of 8.3, the earthquake caused an abundant amount of casualties as well as an outburst of fires that demolished countless homes and buildings. Moreover, after taking the lives of more than 3,000 people as well as the homes of 225,000 residents, many

Chile in 2010, and compare and contrast these two earthquakes to see how the consequences of earthquakes can be reduced. Introduction of The Chile Earthquake The Chilean earthquake on 27 February 2010 occurred at 03:34:17 local time (UTC-3), with a magnitude of 8.5 Mw (United Nations, 2010). This earthquake occurred on the boundary of the Nazca and South American tectonic plates which are converging at a rate of 70 mm per year. The earthquake occurred as thrust-faulting on the interface between the two
coincides with the sides of the Pacific Ocean. The points at which crustal rupture occurs in such quakes tend to be far below the earth's surface, at depths of up to 645 km. Not all subduction zones are subject to frequent earthquakes. The frequency and magnitude of earthquakes around subduction zones are related to the direction in which the plates are moving. If two plates moving in the same general direction come close together, generally the edge of one plate will slide below the other at a sharp angle
Earthquakes can be recorded with seismometers. The magnitude of Richter is the most common scale. Earthquakes are movements of the Earth caused by the release of stress accumulated by geologic faults or by volcanic activity. In the last years, many scientists think that drilling for oil and gas (fracking) causes earthquakes too. There are three different types of earthquakes that will be defined in this discussion. 2: Discussion Earthquakes: The magnitude is used to quantify the
