Look at the two news reports below and reflect on:
What are natural disasters?
Where are the places which are affected by the natural disasters?
When did it happen?
Who are affected?
Why does natural disasters affect tourism?
How can the risks from the natural disasters be minimised?

1. Typhoon

The city of Guangzhou issued its first-ever red storm alert as Typhoon Nida is expected to make landfall today 2 August 2016. All trains departing from Guangdong would be cancelled and hundreds of thousands of passengers affected.  Local official said that it's the strongest typhoon to hit the Pearl River Delta since 1983 and will bring severe flooding. More than 220 flights out of Guangzhou, Shenzhen and Zhuhai airports were cancelled. Cathay Pacific and its subsidiary Dragonair cancelled all of their flights in and out of Hong Kong for 16 hours, from 10.00pm on 1st Aug until 2.00pm on 2nd Aug, affecting more than 100 flights.

Watch the videos below on the two typhoons which affected Hong Kong and China in 2015 and 2016.

Typhoon Chan-hom hit the Chinese coast south of Shanghai on 11 July 2015 with winds of up to 160 kph, as 1.1 million people were evacuated and hundreds of airline flights cancelled,

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.

Watch the videos below on the volcanic eruption of Mount Rinjani which affected Bali, Indonesia in 2015 and 2016.

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.

Taiwan Earthquake 7 Feb 2016

A 6.4-magnitude earthquake struck Taiwan at 4am local time on 7 Feb 2016.

The earthquake started at Kaohsiung but why was the impact greater at Tainan?

The damage at the epicentre Kaohsiung was much lower than Tainan due to the softer soil at Tainan. The impact was also greater as the earthquake  was shallow at a depth of 10km. Many families were at home as it is the eve of lunar new year and casualties were higher as they were sleeping at the time when earthquake struck and were not able to respond or evacuate on time.

The collapse of buildings have caused more deaths and injuries. Queries are made on the structure of the buildings, especially when tin cans were found in the construction. Most new buildings in Taiwan are built to withstand quake of magnitude 5 to 6. The president of Taiwan said that the government will tighten regulation on building construction.
Other than strengthening buildings, what are the other ways to mitigate the impact of earthquakes?

Rescue work is still in progress and is one of the most important short term response.
What are the other short and long term responses?

Earthquake is common as Taiwan lies at the plate boundary of the Eurasian and Philippines Plate.

Why does earthquake occur at the plate boundary?
Why is earthquake a hazard?
Why does the damage from earthquake differ?


A 6.4-magnitude earthquake struck off the coast of Papua New Guinea's Bougainville Island early Tuesday (Feb 9). The quake hit some 96 kilometres southwest of Panguna at 2.19am (12.19am Singapore time), according to the US Geological Survey. The epicentre was 102 kilometres southwest of the larger town of Arawa also on Bougainville Island and USGS said it was 32 kilometres deep, which is considered shallow. Quakes are common on the island nation, which lies on the 4,000-kilometre-long Pacific Australia plate, which forms part of the "Ring of Fire", a hotspot for seismic activity due to friction between tectonic plates.  http://www.channelnewsasia.com/news/asiapacific/6-3-magnitude-earthquake/2499350.html

The earthquake which struck Papua New Guinea has the same magnitude as the one which struck Taiwan. Why are there more damages and casualties in Taiwan? 

Another earthquake struck Chile at 7.33 pm 9 Feb (0033 GMT Wednesday 10 Feb) 326 km north-northwest of Santiago, the USGS said. It had a depth of 31.5 km. There was no immediate reports of damage and injuries.

Impact of climate change on crop yield


WHAT IS AN EL NINO?
* Warming of sea surface temperatures in eastern and central Pacific Ocean that disrupts weather patterns across the Pacific
* Can cause ocean cooling in the western Pacific and around Northern Australia 
* Can deliver more rain to the west coast of North and South America
* Can disrupt trade winds that blow moisture-laden air towards eastern Australia

WHAT ARE THE EFFECTS IN AUSTRALIA?
* Lower rainfall through winter and spring, especially in the north and east
* Temperature extremes
* Warmer-than-average weather, particularly in southern Australia in the second half of the year
 * Decreased cloud and low rainfall
* Worsening heat extremes for cities such as Adelaide and Melbourne, increase in extreme hot days and heatwaves further north
* Increased frost
* Increased bushfire risk
* Fewer tropical cyclones, especially for Queensland
* Later northern monsoon rains
* Below-average wet season rains early
* Reduced winter snowfall




However over at France, the increase in temperature has been good for champagne maker. http://www.straitstimes.com/lifestyle/food/global-warming-good-for-champagne-makers-so-far



The 1.2°C increase in temperatures in the region over the past 30 years has reduced frost damage. It has also added one degree in the level of alcohol and reduced acidity. Harvesting in Champagne has been brought forward by two weeks on average over the past 30 years. And while drought has slashed output in other areas of agriculture, the chalky Champagne soil has water retention properties that have so far been able to temper the impact. And to fight dry weather, winemakers also use techniques such as removing grass competing for water in vineyards or keep more leaves to protect grapes from the sun.

Interesting cartoons on Geography

Interesting cartoons from http://www.ripleys.com/blog/tag/geography/
The Australian Alps receive more snowfall than the Swiss Alps. There are only two individuals in the U.S. who have their own zip code—the president and Smokey the Bear. (Submitted by Chester Tumidajewicz, Amsterdam, NY) During Mount St. Helens’ nine-hour eruption in 1980, the volcano spewed 540 million tons of ash over more than 22,000 square miles! About 50,000 Canadians fought in the American Civil War, including about 200 for the South. (Submitted by Dan Paulun, West Lafayette, OH)
Look at the intensity of the volcanic eruption from the cartoon.  Are you curious to find out more about the Mount St Helens eruption?
