Earthquakes and extent of damage

I have been telling my students about the numerous earthquakes near Solomon islands last week. You can read about it from the channelnewsasia:

How is the magnitude is measured on the Richter scale?
What are the factors which affect the extent of damage?
Why is a shallow focus earthquake more damaging than a deep focus earthquake?
Where are most earthquakes found?

The fear of an earthquake is real and you should know the cause of a tsunamis and the impacts of tsunamis on coastal areas.

Most importantly what are the preparedness measures?
Does the early warning system work?
Has technology helped?

Remember the eBook on the oceans fury? Do check out my earlier post:

National efforts in mitigating climate change

Read the article on

Singapore has made a pledge to stabilise and limit its yearly greenhouse gas emissions to about 65 million tonnes by 2030. 

Singapore has progressively switched from fuel oil to natural gas for cleaner power generation. Today, over 90 per cent of electricity here is generated from natural gas. There is a need for us to attain higher levels of energy efficiency by deploying best-in-class technologies.

What other ways have we been helping in mitigating climate change? How effective are these strategies?

We need to continue our efforts in mitigating climate change by reducing carbon emission or our temperatures in Singapore may soar by 4.6°C by end of the century.

Watch this cute animation on what you can do to help reduce carbon emission and contribute to mitigating climate change.

As shown above there are more warmer days and more intense rainfall in Singapore.

Volcanic eruption affecting tourism in Bali

Read this article on how travel to Bali is affected due to the volcanic eruption of Mount Raung in East Java (natural disaster).

The volcanic ash from the eruption of Mount Raung in East Java has lead to the cancellation of 250 flights and thousands of tourists stranded in Bali on 10 July 2015. Flights have to be cancelled due to reduced visibility from the volcanic ash which posed a hazard in landing.

As posted earlier the outbreak of diseases such as MERS also affected tourist arrivals e.g. in South Korea. 

The economic situation of Greece has also discourage tourist arrivals. What other situations can you think of that affects tourist arrivals?

Preparedness Measures for earthquakes

Read this article on how research in Singapore on building design can help to save lives in an earthquake.

Associate Professor Li Bing has been working on the best way to make buildings quake-proof. In Nepal, for instance, six school buildings which had their beam and column structures wrapped with low-cost materials like wire mesh and glass fibre withstood April's 7.8-magnitude earthquake.

And when disaster strikes in Asia and Pacific regions, Singapore is often among the first to send rescue missions overseas. Meanwhile, the Changi Regional Humanitarian Assistance and Disaster Relief Coordination Centre helps disaster-affected areas by coordinating multi-national military relief efforts.

Visit and play the game.
Record the strategies used in minimizing damage from earthquakes.

Earthquake rocks Nepal

Watch the video on the aftermath of the Earthquakes in Nepal and note down the impacts of the earthquakes.

Read more about it @

A powerful earthquake rocked central Nepal, causing extensive damage to buildings and dozens of injuries and deaths on 25 April 2015. 

The quake measured 7.9 and struck an area between the capital Kathmandu and the city of Pokhara. Tremors were felt across the region, as far afield as Pakistan, Bangladesh and neighbouring India.

Read the article on Channel News Asia on the impacts and some of the short-term response which are critical in reducing the number of casualties. Search for victims, setting up shelters, medical and food.

A 6.8-magnitude quake hit eastern Nepal in August 1988 killing 721 people, and a magnitude 8.1 quake killed 10,700 people in Nepal and India in 1934.
Why is the area prone to earthquake? Are there ways to mitigate the impacts of earthquakes?

The death toll exceeded 4000 on 28 April 2015. More on the short-term response @

Rescue operation, shelter, food and medical aid are critical immediately after a natural disaster. 

Why is this so?
What can be done?
Who can help?
Where would the help be needed?
When must this help be rendered?
How is the rescue work carried out?

What are the measures to reduce the negative impacts of natural disasters in the long-term other than the immediate help given?

International efforts:

As @ 30 April, death toll exceeded 5000 - the survivor rioted against the unavailability of relief from the government. Read the following article and explain why short-term response is critical.

Read this article on 5 May 2015 on more short-term responses - rescue team, medical and food aid, immunization etc.
