The document discusses the increasing frequency of earthquakes globally and in Bangladesh in particular. It notes that in 2011 there have already been 162 earthquakes over 5.0 magnitude worldwide. While major quakes seem to occur elsewhere, Bangladesh has not been unaffected and is ill-prepared to handle a major disaster due to lack of resources. The document outlines some common misconceptions about earthquakes and debunks the theory that intentionally causing small quakes can prevent large ones. It stresses the importance of emergency preparedness and changes needed to building codes to improve earthquake safety.

Earthquake Preparedness
Every disaster has different effects. It can cause permanent damage or temporary inconvenience. This research paper seeks to illustrate how to avoid terrible outcomes of unexpected earthquakes. Every disaster, if prepared for can cause less damage. An earthquake is one natural disaster that has a high rate of damage in its after effects. It is known as the abrupt and fast shaking of the ground caused as rock breaks and shifts due to the strain that has accumulated over a long period (Walker 2008). Earthquakes are one of the major disasters not anticipated, and they end up causing irreparable damage. This paper will use a sample of the San Francisco Bay area. It has a population size of 7,150,739 people as at the census taken in 2010. The Bay Area sits at border where a couple of the earth’s biggest tectonic plates intersect and pass each other. Sometimes, the boundary faults may break. Then the North American plate hurls at the Pacific Plates. This is when an earthquake occurs.
The area has had a number of earthquakes, a trend that scientists cannot take to be random. Some of the earthquakes have a magnitude of 6 and even higher. There is a high frequency of earthquakes. It is estimated that there is a 50% probability that in the next thirty years there will be more occurrences of the same magnitude. Ranging from 1836 to 1911, there was an alarming 18 earthquakes. The Earthquake that occurred in 1906 caused a great strain. This is believed to be the reason for the reduction in earthquakes since only one followed that. The Loma Prieta earthquake had a magnitude of 7.1. It occurred after 1979 (Walker 2008).
Factors that make this area suitable for my proposal are the population of bay area is considerably high, and a great number of people will be affected by an earthquake should it occur. The reason for this is that the area is strategically located between two tectonic plates, making it prone to earthquake occurrence. In addition to this, the continual damage proves that the area needs to take up measures to keep it free from more damage. It could gain from learning about disaster preparedness. These strategies would eliminate the greater risks by foreseeing them and training the residents. From studies carried out bay area is prone to the occurrence of earthquake especially in the future due to the factors mentioned above. Furthermore, only a few individual poses the disaster management skills, which increases fears and further affect the area economic ...

1. The Quake Phenomenon /Jennifer Ashraf Kashmi
Ten years ago earthquakes were treated and considered as rare natural disasters. They were feared that's true, but
news about earthquakes occurring were few and far between. Today, earthquakes have become a common topic of
conversation and frequently aired in the news. The latest earthquake of 8.9 Magnitude in Sendai, Japan on the March
11, has been described as being a 'catastrophic' event, further followed by the 'apocalyptic' images of the resulting
tsunami which hit afterwards. Waves sweeping everything in their path, swirling whirlpools, and the cries of people
for rescue the images are practically impossible to erase. The disaster didn't simply end there, and with barely
enough time for the Japanese citizens to recoup, a third shock followed the nuclear reactor explosion. The
accumulated death and injury toll for all these events lie in the thousands. And the starting factor for this chain of
events was the initial earthquake.
In 2011, we already have 162 earthquakes which have happened worldwide of over 5.0 Magnitude, of which 5
earthquakes are above 7.0 Magnitude. Even though the major disasters seem to be in other countries, Bangladesh
has also not been unaffected in this respect. The increasing frequency of the earthquakes hitting Bangladesh has
become a cause of concern, mainly owing to the fact that we are a developing nation and we do not possess the
adequate resources necessary to enable us to recover from a massive scale disaster. Additionally, the population at
risk is also increasing as well as the population density in all the major cities in Bangladesh (mainly Dhaka and
Chittagong, which are both earthquake-prone areas). Even though everyone is familiar with the concept of
earthquakes, the basic facts are not widely understood by the general population.
Misconceptions about earthquakes are extremely common. One common misconception is that the increased
earthquake activity is a sure-fire indication that a major quake is looming on the horizon. A temporal increase in
earthquake activity does not mean that a large earthquake is about to happen. Similarly, quiescence, or the lack of
seismicity, does not mean a large earthquake is going to happen. A temporary increase or decrease in the seismicity
rate is usually just part of the natural variation in the seismicity. There is no way for us to know whether or not this
time it will lead to a larger earthquake. Swarms of small events, especially in geothermal areas, are common, and
moderate-large magnitude earthquakes will typically have an aftershock sequence that follows.
There is a theory that a majorly large earthquake may be avoided if we artificially generate several small
earthquakes, whilst using triggered explosives in an attempt to do so. This is strongly not recommended as it would
not be a successful alternate option. Even huge amounts of explosives almost never cause even small earthquakes
and it would take hundreds and thousands of small earthquakes to equal a large one, even if it could be done. In
addition, we wouldn't have any control over the size of the earthquake being created if it worked, since small and
large earthquakes all start out in exactly the same way. This theory has been tested, albeit unsuccessfully, by the US
in Central Nevada on January 19, 1968, under the operation codename “Faultless”. The codename was later deemed
to be a poor word choice as a fresh earthquake fault line 1200 metres long was created as a result. If we follow the
Chaos Theory (which follows the concept that minor details can often results in the occurrence of major events i.e. a
butterfly flapping its wings in London can generate a tornado in the Middle-east), then we can predict that this
experiment has already or will eventually result in a major catastrophic disaster, if not in the form of earthquakes
then in some other form. Nature is not meant to be tampered with.
Since earthquakes have now shifted from being a rare occurrence to a fairly common one, it's a useful to have all the
necessary facts regarding how best to deal in the event of an earthquake or even with the aftermath. In the event of
an earthquake, it's usually advisable to leave your house immediately and seek refuge outside. Stay away from
windows, chandeliers or any other glass items and, whilst heading for the doors, be careful that you do not let
yourself get injured by swinging doors. Gather your family together and leave as a group. The theory is as simple as
the one followed in the case of fire never stop to pick up personal belongings. Safety comes first. Just in case you are
2. unable to get out in time, it also helps to be well equipped at home to deal with such a scenario. Emergency supplies
should include first aid kits with instructions, emergency adequate medication, drinking water or chlorine purification
tablets, canned and packaged food with a mechanical can opener, portable radio and extra batteries, walkie-talkies,
etc. Earthquakes can happen anytime and anywhere so you may not necessarily be at home when it occurs. In this
instance it is advisable to also have a few necessities such as canned food, liquid, comfortable shoes, etc. also at
work, just in case.
The cumulative effect of a major earthquake happening in Bangladesh, and specifically in Dhaka, is unpredictable but
foreseeably disastrous. The majority of tall buildings in Dhaka have been built with little or no strong foundations and
therefore highly susceptible to destruction in the event of a strong earthquake. The buildings include both residential
and commercial structures, destruction of which will result in calamitous consequences. Most of these buildings have
lifts and possess no emergency exits such as fire escapes or staircases outside the building which would have been
undeniably helpful. Health and Safety, in respect to dealing with natural disasters, is far from failsafe. Whilst the US
instigated an evacuation programme for its coastal cities likely to be affected by the tsunami in Japan, the degree of
success for any such evacuation procedure in respect to Chittagong and Cox's Bazaar is questionable in any such
event. It is time for the Government to start seriously considering making a few necessary changes in regards to
making foundations a compulsory part of construction and begin educating people about emergency evacuation
instances.
