QU: What are hazard profiles?AIM:To compare and contrast characteristics of major tectonic

hazards in relation to development levels. Starter - Use the dingbats to figure out the covered words.

A previous homework covered these!!

Which of the following hazards is worst? In pairs rank them using the classifications listed.

VolcanoTsunamiEarthquake

1‐Frequency2‐Speed of onset3‐Areal extent4‐Magnitude5‐Recovery rate6‐Damage $7‐Duration8‐Death toll

Task: Rapid fire - You need a mini white board, pen and eraser.

Start with frequency. Pairs holdup rankings. Quickly compareideas and move on to next.

Teacher note

Keep in mind questions/problems

you come across

Mw (Moment Magnitude)

Using just one disaster element does not give us a wholistic picture to compare with. Look at the magnitude of these events. Where would you concentrate your aid efforts?

How does this change things?

Task: Identify a root cause, dynamic pressure and unsafe living conditions which would have contributed to Haiti's obvious increased vulnerability.

Above is a retrospective example of a hazard profile comparing a tsunami and volcanic eruption , these are easier to compare as the criteria that makes up the profile are known and recorded. Many aspects can be compared at the same time to give a more accurate picture (see previous slide). Hazard profiles help governments and other organisations to develop disaster plans. For example the profile for the 2004 Tsunami indicates it's huge areal extent, therefore early warning systems reaching all countries is a priority for planning. The Kilauea eruption on Hawaii is much more localised and long lasting meaning towns nearby need evacuation plans or lava diversion channels built.

Hazard profiles can also be used to compare the same hazards with different physical processes and human vulnerabilities

TASK: On your copy of this sheet use your knowledge to construct hazard profiles. For the last Tsunami profile use the retrospective data (below) to compare the 2004 and 2011 events.Prof

Resilience and vulnerability should be mentioned.

Assess the reasons why, even within a country, some people are more vulnerable to hazards than others. (12)

Weigh up a number of factors and consider which is most significant

Worth defining these terms in the intro!
