The Newcastle Earthquake occurred on 28 December 1989 with a magnitude of 5.6M. Although the earthquake did not measure very high on the Richter scale, it was shallow and that is why it shook Newcastle more than a deeper earthquake. The tremor left 13 people dead and hundreds of people injured and needing hospital treatments. The devastation to property was huge and caused damages to 3000 buildings, 35,000 homes and 147 schools. This earthquake quickly became one of Australia’s most serious natural disasters. The seismograms confirmed that the focus of the earthquake was 10 to 12 km deep within the crust under Boolaroo, an outer suburb of Lake Macquarie. The quake was also felt 163 kilometres south in Sydney and 281 kilometres north in Kempsey.

In 2007, Dr Christian Klose, from Columbia’s Lamont Doherty Earth Observatory presented a new theory that the earthquake was prompted by two hundred years of coalmining. Dr Klose theorised that because of coalmining, stress in the Earth’s crust started to change and over time this caused the tremor. Another Australian report pointed out other factors that may have contributed to the unfortunate natural disaster. It mentioned that minor tremors in the nearby Hunter Valley region prior to the Newcastle Earthquake might have created a fault line that led to the earthquake. Australian Geo-scientists disagree with Dr Klose’s theory and say that because the epicentre of the earthquake was too deep underground, it is not likely to the caused by extensive coalmining.

The San Francisco Earthquake killed many - over 3000 to be exact. Not everything is known about the Earthquake but we do know a small bit, from Art. Paintings, Stories, Films, Photos and more. From these we know about what devastation was caused by the horrific events of the 1906 San Francisco Earthquake. Two of the many ways we know about the Earthquake is “Comprehending Calamity” a Personal Narrative by Emma Burke, and “The Horrific Wreck of The City” an Eyewitness Account by Fred Hewitt.
But people have similar and different views and opinions on this earthquake, and that is seen “Comprehending the Calamity” by Emma Burke and in Fred Hewitt’s “Horrific Wreck of the City”. In 1906, the San Francisco earthquake struck a little after five in the morning. The earthquake, at a magnitude of 7.8, shook and destroyed buildings. At least 250,000 people were homeless, and many camped out in a park. But that wasn't all.
An earthquake strikes, demolishing a home as items plummet to the ground. However, that home is not in California, it is in the middle of Oklahoma. There is no fault line in that part of the country, so how did an earthquake cause so much damage? Was it fracking? Hydraulic fracturing, or more commonly, fracking, is the process of pumping water and chemicals into the ground to extract natural gas.
When was the first earthquake in North Carolina recorded? The first recorded earthquake was on March 8th, 1735 near Beth. Another one on February 21st, 1774 this one was quite noticeable speaking there were some reports from Winston Salem through Virginia. How do tsunamis form?
The last Cascadia earthquake in the 1700s gave the people of that time five minutes to prepare before it happened. If this coming earthquake is similar then the citizens of the Pacific Northwest will not have a long warning before it hits. Cities will be underwater across the coast and the people caught in the chaos can only hope and pray that they will make it out alive. Across Oregon alone it is estimated to be over a million buildings in ruins. FEMA estimates that search-and-rescue teams will be sent out across a hundred thousand square miles of land and across four hundred and fifty-three miles off the coastline.
Northridge Earthquake 1994 Northridge earthquake 1994, one of the most well-known earthquake by Californian people. January 17, 1994, at 4:31 AM this Northridge earthquake struck Los Angeles, California. The earthquake was not happened in the city of Los Angeles, but it happened near San Fernando Valley, 16.5 miles northwest of Los Angeles. With the power of 6.7 Ritcher scale, the earthquake struck the city of Los Angeles, California.
The quivering began to intensify, causing belongings to fall in residents’ homes. It was the beginning of the 5.7-magnitude Oklahoma earthquake, which struck on November 6, 2011 and resulted in significant structural damage (“Oklahoma’s Largest Quake in Decades Buckles Highway; Rattles Residents,” CNN). A journalistic study—published in the journal Geology—conducted in 2013 showed that the 2011 earthquake was actually caused by fracking, a practice in which water is injected into the Earth’s ground (“Wastewater Injection
Recently, on January 7th 2016, there was an earthquake caused by fracking, in Oklahoma, where earthquakes are rare. This particular quake was a 4.8 on the Richter Scale, which is the highest ever recorded. It occurred in the center of the state, was felt all over. Also, within the past week, there have been more than 20 quakes all over the state. in recent years, since 2011, earthquakes have occurred more and more often.
These two plates push and shove each other causing small tremors throughout which can cause landslides,volcanic eruptions and once in a couple years, quakes with devastating results. The strongest earthquake recorded occurred in 1991 with a measure of 7.6 on the Richter scale. This earthquake left 4 dead and buildings as well as bridges and road were completely destroyed. If another Earthquake occurs, the coastal cities would be the most affected ones as they are closer to the plates.
The earthquakes intensity was measured at a magnitude of 7.9 on the present Richter scale (The Great 1906, 4). This earthquake was an extremely vigorous magnitude that would have killed approximately fifthteen hundred to forty five hundred people and injure fifty thousand (House, 51). This was not the first earthquake in San Francisco. 1864, 1898, and 1900 were years of earthquakes striking but not as strong as 1906 (San Francisco of 1906, 1). Ten million California residents who lived closely from the major fault lines could have been in endangered in many extreme ways. (House, 56).
The earthquake of 2010 was a 7.0 on the Richter Scale. This large earthquake caused the death of 230,000 people. This was due to poor building structure and little warning. There were too many bodies to move and so few people who were capable of moving them (due to injuries) that the bodies would just be piled up on roads and in city squares. As a result of the earthquake, a total of 10,000 children were left orphaned.
The text asserts that there were no sweeping fires to blame, only the earthquake. This event led to the first major legislative initiative in California to recognize seismic issues: the Field Act of 1933. Steinberg contends that although this was a step in the right direction, seismic enlightenment was still difficult. The author notes that regardless of awareness, many built in areas vulnerable to harmful seismic activity (i.e. near fault lines). The author also states that California is not the only area prone to earthquakes and that typically the poor suffer more from these events wherever they happen.
Earthquakes are caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two plates are rubbing against each other, they stick a little. Most earthquakes occur along the edge of the oceanic and continental plates. Due to stress they shift and cause the earthquake.
