Factors Affecting Extent of Damage of Earthquakes- Mr Kheng's class by Yong Kai Chung

2017-03-07 04:31:04 UTC

The type of location

Concentration of the affected area

2017-03-08 00:26:19 UTC

This is because even if the magnitude is not very high but the area affected has a lot of people, the earthquake could possibly kill many of them too.

Prepardness of people

2017-03-08 00:27:55 UTC

If the people there are prepared they can know how to protect themselves during an earthquake , resulting in fewer deaths

Population density

2017-03-08 00:34:52 UTC

Earthquakes in sparsely populated areas are likely to affect less people than in densely populated ares. thus, an earthquake can cause more casualties and damage than an earthquake in a countryside.
>Yuxuan_3E1

Time of occurrence

2017-03-08 00:38:39 UTC

If the earthquake occurs during the day, the chances of people surviving will be higher. If the earthquake occurs during the night, when everyone is sleeping, there will be more deaths as people could not escape in time.
-Hui Xuan 3E1

Surroundings of the Area

2017-03-08 00:38:57 UTC

If the earthquake occurs in an area which has more buildings and structures , they may collapse during the earthquakes and cause severe damage to the surroundings resulting in higher number of deaths to people.

Location of earthquakes

2017-03-08 00:39:18 UTC

Earthquakes can occur at convergent, divergent and transform plate boundaries but occur most frequently at convergent plate boundaries as stress builds up when a plate subducts beneath another.
-Aloysius

Type of soil

2017-03-08 00:40:45 UTC

in some location,the soil is more loose and unconsolidated causing the seismic waves to be more amplified and cause more damage.Liquefaction could also occur when the ground becomes unstable and saturated.

The magnitude of an Earthquake

2017-03-08 00:44:40 UTC

If there is a higher magnitude earthquake , the vibrations will be more severe, causing more damage to infrastructure. This will result in more people being displaced.

Preparedness of people

2017-03-08 00:44:56 UTC

People is well developed countries that suffer from earthquakes know what to do so it will reduce the number of deaths compared to less developed countries.For example, Tōhoku,Japan suffered a greater earthquake than Haiti, but 270000 more people died in Haiti as they were less prepared.
-zele

Distance from the epicent

2017-03-08 00:46:36 UTC

Damages by earthquakes may differ due to the location of the epicentre. If it is nearer to the city, more people may not survive and many buildings will collapse unlike when it is away from the city area. Such an example is the earthquake in Christchurch,New Zealand.
<3 Sameerah 3E1

Whether the country is a LDC or a DC

2017-03-08 00:49:16 UTC

If the country is a more developed country,the damage it suffers will be higher as the cost will be high and the building are mostly High rise buildings which can cause more damage when it collapse.
-Ze Kai 3-1

Location of living areas

2017-03-08 00:50:42 UTC

If the epicenter of the earthquake has a densely populated living area on top of it, many people would certainly be affected by the earthquake, causing many to be injured and/or die.
-Timothy.

Depth

2017-03-08 02:45:23 UTC

Earthquakes can happen anywhere from at the surface to 700 kilometers below. Hence, deeper earthquakes are less damaging because their energy dissipates before it reaches the surface.
- Jia Yun 3E2

how developed an area is.

2017-03-08 02:46:06 UTC

A more developed country would have a higher number of tall buildings and cause the earthquake to inflict more damage on the city,also increasing the damage cost for the earthquake. A less developed country would have lesser buildings, and that earthquakes would inflict lesser damage, decreasing the damaged cost.
How Yee, 3-2

Density of building

2017-03-08 02:46:10 UTC

In some cities,the building are very closely packed together throughout the whole city. Therefore when an earthquake occurs, the building topple over. But the people trying to escape have no safe place to go where there is open ground to avoid falling buildings, therefore the dust and rubble will collapse and kill people.
-Xavier and Jerand 3E3 :)

time of incident(earthquake)

2017-03-08 02:47:46 UTC

If an earthquake happens at night and the majority of people are sleeping, the death toll will rise as people react more slowly.

-Emer,3E2

The location of the country

2017-03-08 02:48:30 UTC

If the location of the country is nearer to tectonic plate boundary, the destruction of the earthquakes will be stronger than those further away from tectonic plate boundaries

~Tee Hong, 3-2

LDC vs DC

2017-03-08 02:48:54 UTC

A more developed country will have more preventive measures and lesser impact dealt.
- Wei Le 3E2

LDC OR DC

2017-03-08 02:49:39 UTC

In a DC, there would be a large amount of high-rise buildings around. This will cause a more disastrous impact when it collapse unlike in a LDC where most building would be low level and will not really have a disastrous impact

-AMRULLAH THE LEGEND n KAIWEI

Level of preparedness.

2017-03-08 02:52:54 UTC

A country which is more develop, can be more prepared.They build buildings with a better infrastructure with a advanced engineering and will not collapse easily.
They have emergency evacuation drills which make them more prepared
when in case of a earthquake they know what to do evacuation or seek protection which make safer.-Ren Ce

magnitude of earthquake.

2017-03-08 02:53:30 UTC

A country experiencing earthquake of higher magnitude will experience a strong vibration, thus a more severe consequences will be caused.

-Kai Jie and sean
3E2

Architecture

2017-03-08 02:58:30 UTC

Architecture of the building plays a huge role in who and which buildingsurvives a quake. The January 2010 Haiti earthquake, for example, was made far worse by poor construction, weak cement and unenforced building codes.
Chuan Xun and Haikel -3e2

The stability of the surrounding buildings

2017-03-08 02:58:31 UTC

The buildings are the main cause of death and injuries of people during an earthquake. When an earthquake happens, the city's buildings that is not build properly will collapse and cause more damage than the city with very stable buildings.
~Hawa 3-2

Preparedness of the people living there.

2017-03-08 02:59:28 UTC

If the people living there are more prepared during an earthquake, there would be lesser deaths or casualties. For example, in Tohoku, Japan, although the magnitude is 9.2, there are only 28000 deaths.
-Kai Sheng

Whether the country is a DC or LDC

2017-03-08 03:00:36 UTC

A lesser developed country mostly have houses that are usually about only 2 storeys high compared to a developed country which is filled with skyscrapers. In case of an emergency, residents in developed countries may not be able to run out in time as they have to travel down the building. in a less developed country, the buildings are small and short which makes it easier for residents to evacuate -Namirah :)

Preparedness of residentsa

2017-03-08 03:01:24 UTC

A developed country will be more prepared and earthquakes will be less severe because their buildings are built better such that they have a stronger base and will no collapse as easily. They also practice emergency evacuation drills so that when a real situation really come they will know what to do and they can evacuate more effectively.
Nirvana (18), 3-2

distance from the epicentre

2017-03-08 03:01:33 UTC

the damage caused by an earthquake is more severe when an area is closer to the epicentre of the earth During the earthquake in New Zealand , 2011, the epicentre was a town a few kilomeres away from the city centre . This city suffered more damge than any other areas away from the.
-nat

Distance from the epicentre

2017-03-08 03:01:48 UTC

The damage caused by an earthquake is more severe when an area is closer to the epicentre of the earthquake. During an earthquake in Christchurch, New Zealand, in 2011, the epicentre was in a town a few kilometres away from the city centre. The city suffered more damage than areas further away from the city.
-Zhiqi & Suki 3E3

Distance from the epicentre

2017-03-08 03:02:07 UTC

When a city is more closer to the epicentre , it will suffer more damage . As the seismic activity at the epicentre is more severe . The shock waves from the epicentre will spread out , the cities that are further from the epicentre will receive lesser damage compared to the cities near the epicentre.
Jing En -3E2

Stability of infrastructure

2017-03-08 03:04:36 UTC

Effective building design reduces the chance of the building collapsing and minimizes the damage caused by an earthquake. They can be built to resist the shaking of the ground.
- Mavis 3E2

Time of occurence

2017-03-08 03:08:52 UTC

The time of day during which an earthquake occurs determines where people are and what they are doing. This will affect people's chances of survival in an earthquake. If the earthquake occurs when most people are sleeping at night, there is a higher chance that these people will be trapped in their houses and more deaths may occur. For example, more than 2,400 people died when an earthquake occurred a couple of hours after midnight in the Sun Moon Lake Region in Taiwan in 1999.
~Miraa:3 -3E3 VALOUR

Infrastructure Development

2017-03-08 03:15:38 UTC

infrastructure needs to be developed with advanced engineering to withstand the vibration associated with an earthquake.Effective building design can reduce the collapse of buildings and minimise the damage caused by an earthquake.Roads bridges and dams can be build to resist the shaking of the ground so that they do not collapse ,or can be easily repaired if they collapse.
WangJin&Leena-3E2

Time of occurance

2017-03-09 11:50:20 UTC

People are doing different activities at different times of the day . The time where the earthquake strikes play a huge part in determining if it is severe as people might not be able to do the necessary evacuation . This is where the level of preparedness of residents come in . Due to the incapability to evacuate , the earthquake may take away more lives and thus resulting in a severe earthquake .

- Ryan Koh

Level of preparedness

2017-03-13 02:51:45 UTC

The damage caused by earthquakes can be huge, but if the people are prepared to deal with the earthquakes, the damage will be more manageable.
-Jasper 3E1

Distance

2017-03-13 13:33:10 UTC

Earthquake intensity is affected by both the distance along the surface the earth and how deep the earthquake is below the earth. They have been earthquakes that were very severe but didn't cause much damage, because they occurred a long way from places that humans live. Earthquakes can also hit anywhere from the surface to about 450 miles below the surface. By the time a deep earthquake has reached us, its energy has often dissipated through the ground, leaving left to do the damage.
- jin Qin

Time of occurence

2017-03-13 14:03:59 UTC

Most people are active in the daylight than night time. Thus, they have a better sense of alert and urgency when they are awake and doing daily things. They would be able to react faster when an earthquake occurs. They would be able to evacuate from buildings quicker.

- Sofiaaa :) 3E1

Severity

jeong_hanhan — 2017-03-14 13:49:29 UTC

The severity of the earthquake matters as some earthquake are not as violent and sometimes cannot be felt , while the higher the severity of the earthquake the higher the amount of damages.
-zhiying , 3-2

Distance of the focus to the epicenter

2017-03-16 03:10:40 UTC

The further the focus is away from the epicenter the weaker the seismic waves that hits the surface of the earth. Hence the smaller the magnitude,the lesser the damage to the people and infrastructures

Justina 3E2

Population in an Area

2017-03-16 11:34:37 UTC

If a country or city has a greater population, the earthquake will affect a larger group of people than an unpopulated area.

Joey Poon 3E2

Location of earthquake

2017-03-17 02:37:38 UTC

If earthquake occurs in a less populated area, the impact will be smaller. If it occurs in a city which is a more crowded and dense area of the country, most of the buildings will be more packed together and will be taller. when earthquake strikes, if one of the building collapse, it might collide with the other buildings surrounding it, this then causes a domino effect, thus destroying more properties.

- Jia Xuan 3E3

Population density

2017-03-17 05:44:04 UTC

Areas that have high population density are likely to experience more damages since having a higher population density requires more infrastructure to be built to accommodate them. Buildings that collapse will harm others, increasing the chances of death rates.
-Natasha 3E2

How developed the country is.

2017-03-17 08:25:34 UTC

Less developed countries will have lesser buildings. So when an earthquake occurs in a less developed country, damages caused will not be as severe as developed countries. More developed countries have a lot of high rise buildings. Thus when an earthquake occurs, it will suffer from more sever damages, because the buildings may collapse.

Eliza 3E1

Distance from epicenter

2017-03-18 13:39:41 UTC

The epicenter has the most violent vibration. The further the distance from the epicenter, the less violent the vibration. When the vibration is less violent, it will lead to a smaller extent of damage and vice versa.
- Zhao Rui_3E1

Distance from the epicenter.

2017-03-21 08:07:39 UTC

A city that is closer to the epicenter would be more destructive compared to a city that is further a city that is further away from the epicenter of the earthquake

Lucas Tay 3E2 Apache

Location`

2017-03-22 12:19:40 UTC

A country that is near the epicentre of the earthquake will suffer more damage and have more casualties while a country that is further away from the epicentre might suffer lesser damage and lesser casualties or might just a feel a light tremor

~Brayden 3E1

Level of preparedness

2017-03-22 13:42:02 UTC

Earthquake can be impactful however if the people are prepared , the damage will be reduce greatly.

-Qi Sheng 3E1

Location of the earthquake

2017-03-22 13:45:05 UTC

If the earthquake occurs closer to a plate boundary , then the effect will be a disaster. However , if it is further away from a plate boundary , it will be less destructive . If the earthquake occurs in a more built up location with more buildings , then there will be more destruction as the building collapse .

-Peiyu 3E1

Time of occurence

2017-03-22 14:26:51 UTC

If an earthquake occurs at night, large majority of people would be sleeping, which will result in less time for them to evacuate to safety. Hence, some earthquakes are more devastating than others.

-Da Fu 3E2

Level of preparedness

sim_boon_suang — 2017-03-22 14:47:48 UTC

When the earthquake is located in a city that has high-rise buildings, cramped road and citizens who are unprepared due to lack of experience with any earthquakes, there will definitely be a higher rate of deaths and injured.
When it occur in placed where there are also high-rise buildings, cramped roads, but have citizens who are prepared, they would know what to do during an earthquake instead of panicking and screaming helplessly. This will result in lesser deaths and injured.
- Boon Suang 3E2

Distance from the epicentre

2017-03-22 15:14:23 UTC

The damage caused by earthquake is more severe when the area is closer to the epicentre of the earthquake. One example is during the earthquake in Christchurch, New Zealand, in 2011, the epicentre was in a town a few kilometres away from the city centre. The city suffered more damage than areas further away from the city.
-Seri Ariqah Bte Shahri 3E2

Level of preparedness

2017-03-23 14:11:01 UTC

If the citizens knew what to do during an earthquake ,example where to go when an earthquake occurs, the chances of people surviving would be much higher than when everyone do not know what to do and panic this way more people would lose their lives.
-Yu En :) 3E1

The strength of the buildings

2017-03-25 06:27:59 UTC

The strength of buildings affects the amount of damage that the earthquake can do. During an earthquake, if the buildings weren't properly built and with strong, stable materials, it will not be able to withstand the earthquake and stand after one.
Min Kai 3E1

Distance from the epicentre

2017-03-25 14:09:34 UTC

The nearer the location to the epicentre, the greater the destruction. The location nearer to the epicentre will have more impact than the location located far from the epicentre.

Alyaa 3E3

Strength of building

2018-04-12 03:26:12 UTC

The strength of earthquake is important as there are many people working in building that are tall so when a building is not strong enough and it collapse more people will die.

LDC vs DC countries

2018-04-12 03:27:42 UTC

developed countries is able to save more lives it has the technology to save people from the earthquakes,while in less developed countries, they do not have enough technology or resources to help the citizens .
sin haw 3-3

Distance from the epicentre

2018-04-12 03:29:46 UTC

The nearer the city is to the epicentre of the earthquake, the city would experience a higher vibration than those further away from the epicentre . This could lead to a higher extent of damage.

Distance from the focus and epicentre

2018-04-12 03:34:10 UTC

affected area is near the epicentre but the focus is very far down into the earth the affected area will not be affected very much

distance from

2018-04-12 03:34:16 UTC

Distance from the epicentre.

2018-04-12 03:38:22 UTC

If a country is right above the epicentre,even if it is magnitude of 4.0, there will still be great damage to the country. If the country is very far from the epicentre, even if the magnitude is 8.0, the damage is lesser than those on the epicentre as the seismic waves is lesser as it is lost to the surrounding.
Xin Hui 3E3

2018-04-12 03:41:32 UTC

If a city is closer to the epicentre, it will suffer more damage as the seismic waves are stronger.

2018-04-12 03:51:31 UTC

Earthquake intensity is affected by the distance of the focus or epicentre.The nearer it is to the epicentre the more violent the earthquake will be. thus destroying more properties and endagaring more live._ Irfan Naufal 3E4

Location of the city

2018-04-12 03:51:58 UTC

If the location of the city is closer to the epicentre , the damage will be greater then those city which are further away from the epicentre as the seismic waves will be stronger.
- Charisse 3E3

Preparedness

2018-04-12 03:52:08 UTC

Less developed countries might have have the necessary technologies to detect earthquakes or to predict when an earthquake will strike,but developed countries does. Developed countries,upon estimating when the earthquake will strike could set up preventive measures or evacuate measures that could minimize the damages and costs of the earthquake.
-Kaylyn

2018-04-12 03:56:27 UTC

Location that the Earthquake occur
If the earthquake hit the area with many people staying, there will be more damage compared to when an earthquake hit places with lesser people staying.
- Janessa 3E4

Distance from the epicenter

2018-04-14 14:54:22 UTC

The closer the city to the epicenter, more damage will be dealt.
Keng zheng 3E4

Location of the citiy

2018-04-14 16:01:59 UTC

If the city is near the epicentre, more energy would be released and thus the ground would vibrate violently. However, If the city is located further away, the vibration would be lost to the surroundings thus the speed of vibration would decrease and lesser destruction would be caused
Koh Qien -3E3 tree

Time of Occurence

2018-04-15 05:40:58 UTC

If the earthquake occurs when most people are sleeping, there is a higher chance that these people will be trapped in their houses and more deaths may occur.

Naquib,
3E3

Distance from epicenter

2018-04-15 07:14:41 UTC

The epicenter is the point at the surface right above where the earthquake originates and is usually the place where the earthquake’s intensity is the greatest.
Joel Goh 3E3

Time of occurence

2018-04-15 11:05:31 UTC

If the earthquakes occurs at night, most people would be sleeping and this increases the chances of people being trapped in their houses and more deaths will occur.
-Kenneth 3E3

Occurence timing

2018-04-16 14:01:56 UTC

when earthquakes happen during peak hours or when most people are working more people will be trapped in the buildings.

time of occurence

2018-04-25 12:56:38 UTC

if the earthquake occurs in daytime, people will be better aware and hence able to evacuate as soon as possible. but if the earthquake occurs at night, while everyone is asleep, they will be unaware and by the time they realize it, damage may already occur because they were unaware and unprepared to evacuate.
