Earthquakes can cause great damage. Over the past few years there have been a total of 56-80 earthquakes. It has endangered many residents and will continue to. Earthquakes are very deadly and many peoplei in San Francisco may agree. Between the fire and the earthquake no one will ever be sure which one caused the most damage. On April 18, 1906 at approximately 5:12 am a fire started in San Fransisco. A rupture along the Tomales-Portola which is also known as the San Andreas fault line caused the earthquake The city of San Francisco was located along the San Andreas Fault line. The San Andreas Fault extends 810 miles through California. About 270 miles of ground surface was ruptured in Northern California. The epicenter was located near San Francisco.The Great San Francisco Earthquake caused the ground to shift at about 4 to 5 feet per second, and the rupture traveled at about 5,900 miles per hour. The magnitude of the earthquake was estimated to be 7.8. on the Richter scale. Earthquakes happen along fault lines, the lines where tectonic plates meet. Tectonic plates are the huge rocky plates that make up the surface of the earth. Tectonic plates can move apart or collide with each becaue of pressure. This powerful movement tears apart the surface of the Earth releasing energy like shock waves which cause earthquakes. The two tectonic plates that interacted to cause the earthquake were the Pacific Plate and the North American Plate on the boundary line that is…
shook. It was then announced by the Governer that this was completely un expected. It was an Earthquake. The plates that clashed were not supposed to crash in the next hundred years. But, for some reason they were “moved” faster than ever possible. People began to Gossip wondering what caused such destruction. As seven million people were killed.
Cajos has stricken the north American plate. Earthquakes have been popping up out of no were all day. The number of people killed has sky rocketed. As…
“Earthquake” was directed and produced by Mark Robson’s in 1974. The Film gives viewers a look upon a catastrophic earthquake that occurs in the metropolis, Los Angeles, California from before and after the earthquakes.
Through out the film there are three main themes that would I will discuss. I will look upon analyzing it in a disaster and emergency approach and not as movie critics. These themes consist of emergency management and how it is portrayed then ill be addressing how people are portrayed…

Hazard Management in Response to Earthquake Occurrences - Newcastle 1989 vs. Kobe 1995
Characteristics of the Hazards
The Newcastle earthquake of 1989 is still, until
this day, known as one of Australia’s most severe
natural disasters. With the epicentre at Boolaroo,
occurring roughly 15 kilometres west south west
from the heart of Newcastle (32.967° S,

PRINCE WILLIAM SOUND EARTHQUAKE OF 1964
The Prince William Sound Earthquake in Alaska, accord on March 27, 1964 with a magnitude of 9.2. This earthquake is the second largest earthquake ever recorded in the world, with a duration rupture of four minutes. This earthquake took many lives, damaged a mass area of the earthquake, and created a devastating tsunami following the earthquake. This earthquake was not only felt in Alaska, but also in parts of Yukon, some parts of Canada…
Richter scale: used worldwide to describe an earthquake magnitude. It gives an estimate of the amount of energy used.
Seismology: Scientific study of the waves earthquakes generate
Seismologist: A person who studies seismology
Seismic waves: Consists of elastic energy which radiates out in all directions from the earthquake focus
Seismograph: An instrument that DETECTS AND RECORDS
Seismogram: PAPER COPY (candygram)
Seismometer: Inside the seismograph
Amplitude: size of waves…
The nature of an earthquake
Earthquakes are caused by the sudden release of energy within some limited region of the rocks of the Earth. The energy can be released by elastic strain, gravity, chemical reactions, or even the motion of massive bodies. Of all these the release of elastic strain is the most important cause, because this form of energy is the only kind that can be stored in sufficient quantity in the Earth to produce major disturbances. Earthquakes associated with this type of energy…
1- Earthquakes create dust, debris and gas emissions which release toxic gas which pollute our air. Earthquakes can also trigger volcanic eruptions which can cause more carbon to be in the air.
2- 1968 Illinois earthquake. It caused significant structural damage to buildings, the toppling of chimneys and shaking in Chicago. It affected 23 states and measured up to 5.4 on the Richter scale.
3- Earthquakes are measured on the Richter scale. They are classified as dangerous from as…
Could this B.C. Earthquake the Largest in Canada?
After a sleepless night of tsunami warning, an earthquake with a magnitude of 8.2 has struck on the northwest tip of Vancouver island around 2:35 A.M this Wednesday also covering other parts of BC.
This is the largest earthquake recorded in the history of Canada leaving about 850 people injured; 102 dead and 31 missing. At least 12 buildings have been red-tagged, which means that they have been designated as unsafe to enter,
Scientists say the…
“Earthquakes have a greater impact when they happen in poorer parts of the world” Discuss
Earthquakes are a natural phenomena that, when occurring near civilisation, can and almost always do cause grief and harm to those caught in the shock waves or after effects. The severity of impacts from earthquakes are obviously dependent on the countries that are affected; for example a richer, but more densely populated and constructed country can suffer significantly more than a poorer, but more sparsely…
