THE EFFECT OF STRUCTURAL POUNDING DURING SEISMIC EVENTS Abstract This project entitled aims at the investigation of the effect of structural pounding to the dynamic response of structures subject to strong ground motions. In many cases structural pounding during earthquake may result in considerable and incalculable damages. It usually need to be accounted for in […]
Introduction Background The population of the world is constantly increasing; it currently lies at 6.7 billion people and is predicted to increase to 9.2 billion in the next forty years. Majority of this growth will occur in urban areas and it is predicted that by the year 2050 urban areas alone will contain 6.4 billion […]

Get startedAbstract Earthquake is an independent natural phenomenon of vibration of the ground which can become dangerous mainly when it is considered in relation with structures. Earthquakes can be very weak, without even realizing them but (they) can also be strong enough to result serious damages to buildings which can lead to injures or even loss […]
The earthquake occurred in the Wenchuan area in China on May 12th 2008, was a catastrophic disaster that was the most destructive with the most difficult disaster relief since new China was founded. Although with joint efforts of the Chinese government, the army and people from all NGOs and civil society groups, the earthquake relief […]
Patricia Gardner ENG 201 : 8:00 Assignment 1: Natural Science Ocean Inside the Earth’s mantle The mantle takes up 84 percent of the Earth’s structure and is composed of my different layers. Knowledge of the upper mantle is that it includes tectonic plates, magnetic pull, heat flow, and gravity studies. A new discovery has been […]
Plate Tectonics The forces that shape the earth begin beneath the lithosphere. Rock in the asthenosphere is hot enough to flow slowly. Heated rock rises, moves up toward the lithosphere, cools and circulates downward. Riding above this circulation system are the tectonic plates, enormous moving pieces of the earth’s lithosphere. [pic] Plate Movement Tectonic Plates […]
On March 11, 2001, an earthquake with a magnitude of 9.0 on the Richter scale hit Tohoku, Japan, the biggest earthquake in the history of the country. Along with over 15,000 deaths, the earthquake and the subsequent tsunami caused significant damage to the Fukushima Daiichi Nuclear plants (Oskin, 2017). The radiation leaks from the damaged […]
During the earthquake, I will be in 2nd period and the period is 20 mins from being over, and i’ll be doing my homework early and Mr. Crowell tells us to get under our desks and that an earthquake will be striking in a few minutes max. So we do and don’t you know it […]
There are so many things happening in our world that it’s hard to keep up with everything that going on. One thing that not many know about are the earthquakes in Alaska. Lots of people are surprised to find out that Alaska has earthquakes. Though Alaska is actually pretty used to earthquakes. Alaska records an […]
My Dearest Mother, Devastation was stricken in all hearts of the San Franciscans, including myself . All of our buildings were in Pieces or in flames . Everyone got out of their buildings in work clothes, pajamas, anything they had on before this destruction occurred . Most people had not known what was going […]
Earthquakes Individuals tremble when they hear the word disaster: all words that ring a bell when “earthquake” is heard. They happen all of a sudden and cause a great many dollars in reconstruction. Therefore, the sky is the limit from there, seismic tremors are a standout amongst the most terrific events The unstoppable force of […]
Earthquake in the sea between Italy and Greece Tsunami Italy, climbed the sea level A powerful earthquake, of magnitude 6.8, struck last night just before two o’clock in the morning (one in Italy) the west coast of the Peloponnese, in Greece, causing great fear but fortunately no victims, and only limited damage . The epicenter […]
At 4:53 p.m. on January 12, 2010, an earthquake with a magnitude of 7.0 struck Haiti. Within 20 minutes of the initial shock, two large aftershocks followed with respective magnitudes of 6.0 and 5.7. Leog- ne is the epicenter, a town approximately 15 miles southwest from Port-au-Prince, the Haitian capital. This location is near, if […]
Earthquakes are one of the most devastating natural disasters on the planet. They have killed countless amounts of people and are hard to tell when coming. In this essay I will being talking about the experiences and how it feels to be in an Earthquake. The most devastating earthquake on record happened in 2004. […]
On Friday, November 30, a magnitude 7.0 earthquake hit Anchorage, Alaska shocking many individuals and causing panic for them and their families. The shaking started with a sharp jolt and continued for one minute. The earthquake happened around 8:30 am, and although no deaths were reported, some individuals are being treated for lacerations due to […]
Earthquakes are super deadly especially if you are in the wrong place. Like if you in a house surrounded by furniture than you have a likelihood of dying. There are 12,000 to 14,000 earthquakes a year. A 7.0 earthquake can be 10 to 30 minutes long but they are still very dangerous.Indonesia, Sri Lanka, India, […]
Earthquakes in Japan has become more frequent these last couples of years. Japan is considered the eighteenth largest country in Asia with 145,914 square miles (377,915 sq km) (Briney 2018). Out of many Asian countries, Japan was one of the countries in Asia that had the worst earthquakes happened to. Why is Japan prone to […]
This project investigates trees, earthquakes, atmosphere and ionosphere as a coupled system to see if trees can be used as precursor for short term earthquake prediction alongside other long, intermediate and short term precursors. History has shown animals can and have predicted earthquakes (Cao et al., 2018, Tong 1988), but the general tone of this […]
In the early hours of 24 August 2016, an earthquake of magnitude (the amount of energy released) 6.2 struck Central Italy, southeast of the Umbrian town of Norcia, followed by violent aftershocks, causing 297 deaths and approximately 400 injured. Serious damage occurred in the regions of Lazio, Umbria and Marche, historically prone to seismic hazards, […]
Specific purpose: inform my audience on the dangers of an earthquake and what to do in case of one. Speech thesis: Due to the recent catastrophic events such as the Mexico City earthquakes, it is important to inform ourselves on what we can do in case of an earthquake. Introduction: On September 7, 2017 a […]
It is no surprise to Earth Scientists that Alaska sees so many earthquakes annually. With two tectonic plates meeting under a subduction zone there is bound to be a great deal of seismic activity. There is a long history of quakes, some taking several lives, that has become a lifestyle more than an occurrence. Alaska […]
Background In the past several decades, Qatar has been included the low probability expectation from any major naturally-occurring incidents like earthquakes, floods, droughts or heavy storms. A United Nations report published ranked the country as among the world’s safest. An earthquake is a sudden, rapid shaking of the earth caused by the shifting of rock […]
It’s 5:12 AM, April 18, 1906. Extremely loud low pitched rumbling wakes many people up from their sleep. This rumbling sound was caused by the Pacific and American Tectonic plates scraping along each other at the San Andreas fault. A shock suddenly hits San Francisco, and it shakes the ground for 45 seconds. Another tremblor […]
A seismometer or seismoscope is an instrument that detects and measures the motions of the ground as a result of seismic waves gushing from an earthquake, volcanic eruption or powerful explosion. Today, there are thousands of such instruments dispersed in key places around the world that constantly keep watch, gather data and help seismologists better […]
