Question 1

5 Limitations of managment

Answer 1

Man vs nature 
Scale 
Environment 
Ceteris Paribus 
Economic development

Question 2

Man vs Nature argument

Answer 2

Damage unavoidable in some areas such as fishing

Japan 10% of fishing ports damaged and Indian Ocean 65% of fishing fleet damaged as cannot react to 15minute landfall

Question 3

(4) Scale limitation

Answer 3

13.5million living on N.Sumatra means ability to mitigate minor
9.0mm magnitude earthquake created tsunami beyond Japan’s Meteorological agency
Indian Ocean 9.1mm (3rd largest recorded)
Exceeded Japanese defence capacities, surprising as only 58% of people headed to high ground

Question 4

(3) Environment

Answer 4

Indian Ocean 2km fetch up rooted surface level objects
Biggest export coffee vulnerable to flooding
Year after disaster fish along Japanese East coast still 250x’s more contaminated than safe for eating

Question 5

(2) Ceteris Paribus

Answer 5

Due to diffraction it allowed tsunami to affect more areas also areas were unprepared
JPF slow and responsive response result of disaster beyond contingency

Question 6

(2) Economic development

Answer 6

230,000 deaths vs 16,000 but same amount from drowning shows impact of early warning (Japanese in danger warned via sms within 3 minutes/ tsunami hit N.Sumatra in 15mins without warning)
Death toll fell sharply in Japan with time from landfall whereas in Indian Ocean it stayed high
