Earthquake struck New Zealand

A 7.8-magnitude earthquake and a series of powerful aftershocks left thousands stranded in a New Zealand town near the quake's epicenter. A local state of emergency has been declared for the region of Canterbury, which is home to the areas hardest hit by the quake. Helicopters are being sent to airlift trapped tourists and locals from cut-off communities in the Hurunui and Kaikoura districts.
There have been between 80,000 to 100,000 landslides since the main quake with areas of the Inland and Seaward Kaikoura Ranges the most affected. As a results, a  number of roads are closed indefinitely.

Singapore using less electricity and water

Home electricity consumption per capita fell from 115.7kWh in 2006 to 108.7kWh  in 2015. This could be due to more people using more energy efficient household appliances such as air-conditioners and refrigerators.

The Paris climate pact seeks to limit global warming to under 2 deg C above pre-industrial levels, and countries, including Singapore, have committed to implementing measures to reduce greenhouse gas emissions. Singapore's climate policy is based on three pillars - fuel switching, increasing energy efficiency, and developing renewable energy. Most of Singapore's electricity is already generated by natural gas, the cleanest form of fossil fuel. But there are limitations, such as the lack of suitable sites, to tapping renewable energy sources.

Typhoons hit Taiwan Sept 2016

Watch the video clips below and reflect on the following:
1. Describe the weather conditions associated with a tropical cyclone. (pay attention to the wind speed, rainfall and the calm condition of the eye)
2. Explain the hazards brought by tropical cyclone as shown in the video clips. (storm surges, heavy rain, mudslides, strong wind)
3, How can the risks brought by typhoons be reduced? (strength and limitation of measures such as prediction and warning as shown in the video clips,  landuse regulation and reducing vulnerability of infrastructure)

Updated - 3 typhoons hit Typhoon in 2 weeks - Typhoon Megi struck Taiwan on 27 Sept 2016.


Taiwan suffered a direct blow from Typhoon Megi on 27 Sept 2016, which killed at least four people and injured more than 250 people, many of which were caused by flying debris during the storm. Among those hurt were eight Japanese tourists who were inside a bus that overturned.
Earlier on 14 Sept 2016,  Taiwan was hit by another Super Typhoon Meranti which had brought strong winds, torrential rain and flooding to many parts of Taiwan.



Typhoon Meranti has finally moved on after pounding southern Taiwan and Jinmen County with record-setting winds, but right on its heels is another storm, Typhoon Malakas. The Central Weather Bureau expects Malakas to affect the northern half of Taiwan late Friday(16 Sept) and Saturday before heading toward

2. Volcanic eruption Volcanic ash from Mount Rinjani has caused several flights, including those from Bali to Lombok and several Australian destinations, to be disrupted. Thirteen of the domestic and international flights disrupted due to the eruption were meant to take off from or land in Bali's Ngurah Rai airport. The Lombok International Airport in Praya will also be closed from 4.55pm (local time) to 10am on 2nd Aug 2016. An ash cloud from the active volcano has affected air travel. In November 2015 and hundreds of flights were grounded after Ngurah Rai airport was closed for two days due to its eruption.

Increase in Dengue Cases in Singapore

A total of 7,370 dengue cases have been reported in Singapore since the start of the year 2016. Four people have died of the disease so far – a 47-year-old man who lived in Marsiling Rise, a 67-year-old man who lived in Toa Payoh, a 63-year-old woman who lived in Bedok and a 73-year-old woman who lived in Hougang.


The Ministry of Health and NEA have warned that the number of dengue cases in Singapore may exceed 30,000 this year, higher than the record of 22,170 reported in 2013. One of the main factors is the rising temperatures which caused faster breeding and maturation cycles of the Aedes mosquito population.

Earthquakes struck Japan

Two powerful quakes hit southern Japan a day apart, killing at least 41 people as@ 18 April 2016. The first one with a magnitude of 6.2 struck on Thursday 14 April 2016 and the second one with a magnitude of 7.3 struck on Saturday 16 April 2016.

The epicentre of Saturday’s (April 16) quake was near the city of Kumamoto and measured at a shallow depth of 10 km , the United States Geological Survey (USGS) said. The shallower a quake, the more likely it is to cause damage.

Buildings were reduced to rubble, including a university dormitory and apartment complexes, with dozens of people unaccounted for over a wide area.

Around 70,000 people have been evacuated, including 300 from an area close to a dam thought to be at risk of collapse. A hospital was left teetering by Saturday morning's 7.0 quake, with doctors and patients rushed from the building in darkness.

Isolated villages in the mountainous area of Kumamoto were completely cut off by landslides and damage to roads, with at least 1,000 people believed trapped in one area alone.

Aerial footage showed a bridge on a main trunk road had crashed onto the carriageway below it, its pillars felled. The quake came as emergency responders were working to reach areas already affected by a 6.2 magnitude tremor that struck late Thursday.
Aftershocks continued to rock Kumamoto and its surroundings, an area unaccustomed to the powerful quakes that regularly shake other parts of seismically-prone Japan.

Thursday's initial quake affected older buildings and killed nine people, but Saturday's brought newer structures crashing down, including a municipal office in the city of Uto.
The total number of deaths rose to 32.
Nearly 1,000 people have been hurt, 184 of them seriously.

Japan, one of the most seismically active countries in the world, suffered a massive undersea quake on March 11, 2011 that sent a tsunami barreling into the country's northeast coast.

Some 18,500 people were left dead or missing, and several nuclear reactors went into meltdown at the Fukushima plant in the worst atomic accident in a generation.

Response to Typhoon

An article released on 13 March 2016 reviewed the efforts of the Philippines government in helping the victims of the typhoon Haiyan which struck in 2015.

What are the responses?

  • Call for more typhoon-proof architecture, but many residents are still living in temporary housing. 
  • As of 2015, only 10 per cent of permanent housing has been completed, leaving thousands still living in temporary bunkhouses across the city. 
  • More than half of the US$12.8 billion earmarked for housing projects had yet to be used. 
  • In Tacloban, almost 14,500 housing units had been targeted to be built on 21 resettlement sites, but only 660 units - less than 5 per cent - have been completed. 
  • Many in the city are still living in transition. Though permanent homes have been built for them, only half have moved out of their temporary bunkhouses as there is no water and electricity at the new sites


What happened?


  • More than 360,000 homes were left destroyed in Eastern Visayas in 2013 as a result of Typhoon Haiyan, one of the strongest tropical cyclones to hit the country. 
  • The area was the worst hit by Typhoon Haiyan, with more than 95 per cent of its population living beside the sea or near bodies of water before the typhoon. 
  • The Philippines' precarious position in the Pacific also means it is first in line to receive more than 20 typhoons each year. 
  • The government had initially set a target of moving communities 150 metres above sea level and aimed to build structures able to withstand wind speeds of up to 300km per hour.
