1 But how reliable are these statistics?
Reliability of Disaster Statistics It depends on whether direct (primary) deaths or indirect (secondary) deaths from subsequent hazards or associated diseases are counted. Location is significant because local or regional events in remote places are often under recorded. Declaration of disaster deaths and casualties may be subject to political bias. Statistics on major disasters are difficult to collect, particularly in remote rural areas of low human development countries (LHDs). Time-trend analysis (interpreting historical data to produce trends) is difficult.

2 Let’s have a look at two examples
Using the templates provided you are going to research 1 example of mega-disasters from either: 2010 Eyjafjallajokull volcano 2011 Japanese Tohoku tsunami You’re going to exchange notes with your partner on the other 

3 LO: To understand the concept of a multiple-hazard zone.
Key Enquiry Question 3: How successful is the management of tectonic hazards and disasters? LO: To understand the concept of a multiple-hazard zone. Which countries stand out as being the most hazard prone in the world?..... Any ideas?

4 What trends can you spot?
Tropical Cyclones Earthquakes/ volcanoes Hailstorms Tornadoes

5 Background Hotspots are likely to be were plate boundaries intersect with major storm belts in areas of high human concentration in low or medium developed countries 2001 a project was started to begin to identify disaster hotspots (at country level but also within a country) These hotspots are known as multiple hazard zones. The project assessed the risk of death and damage This was estimated by combining the exposure of six major natural hazards – Earthquakes, volcanoes, landslides, floods, drought and storms. Combined historical data with potential vulnerability based on size, density and poverty of the population. Tectonic Hydro- metrological Vulnerability

6 Guess Who? Experiences more natural disasters than any other country 40% of population live below the poverty line Has an average of 10 typhoons per year Is located on the ‘Ring of Fire’ Is made up of 7,107 islands – only 2773 have names! The national language is the Tagalog The volcano Mt Pinatubo can be found Has the capital Manila Philippines

7 California Coast Guess Who? Has over 1500 earthquakes per year
Sits right across the San Andreas Fault Has an economy which would rank as the 7th largest in the world if it were a nation Is home to 1 in 8 of the USAs population Is the home of the USAs official Christmas tree – a giant sequoia 300 ft tall Had a former film star for a Governor Produces more than 17 million gallons of wine per year California Coast

8 Earthquakes, volcanoes, landslides/lahars, typhoons, flooding
California Coast Philippines Average income (US$) Country type Human development index Annual population growth Under 5 mortality rate Physical geography Hazards 45,000 HIC 0.7% 7 per 1,000 RIC 2.3% per 1,000 1,415 Plains and mountain ranges Numerous volcanic islands Earthquakes, volcanoes, landslides/lahars, typhoons, flooding Earthquakes, tsunamis, flash floods, fire RIC – Rapidly industrialising

9 California Coast Philippines
Average income (US$) 45,000 1,415 Country type HIC RIC Human development index 0.95 0.78 Annual population growth 0.7% 2.3% Under 5 mortality rate 7 per 1,000 40 per 1,000 Physical geography Plains and mountain ranges Numerous volcanic islands Hazards Earthquakes, tsunamis, flash floods, fire Earthquakes, volcanoes, landslides/lahars, typhoons, flooding RIC – Rapidly industrialising

10 What are Disaster Hotspots?
Disaster hotspots occur when two or more hazards occur in the same location. In many cases, one hazard triggers or exacerbates another for example earthquakes trigger landslides. Disaster hotspots are the world’s most unpredictable and dangerous locations. The Philippines and the California coast are compulsory case studies that we are going to look at.

11 Your homework task As a group you are to present a case study of The Philippines as a location that experiences several hazardous events. You are investigating how hydrometeorological hazards sometimes contribute to tectonic hazards, so there must be a link e.g. an earthquake event made worse by a cyclone event shortly after. I suggest you split up the information below between your group and produce small snippets of info that can be stuck on an A3 piece of paper when you come to the lesson on Friday.

12 What about smaller geographical areas?
Think about trade... Think about what has happened to the environment... Think about population density... Think about dependency on services... Discuss what pupils know of megacities from previous learning, they are to suggest why some megacities have low hazard resilience. Think about how the houses are constructed... Think about planning (particularly housing)...
