Why are some tectonic events more deadly than others? (KE)
Preparation
Education
well educated (usually more common in ACs)
many people have "grab bags" readily packed for emergencies
regular drills are held so people know what to do in case of real tectonic events
the "drop, cover and hold on" technique is taught so that people can protect themselves against risks such as falling buildings
poorly educated
not all countries educate people on what to do in case of emergencies such as tectonic events. This may not be an issue if the area is far from a tectonic plate boundary, however it could cost lives if the people in areas with a lot of tectonic activity are not properly educated.
Measuring and Monitoring
scientists can record everypiece of information about every earthquake, however small (magnitude, time, location) using; the Richter scale, the Mercalli scale and seismic gaps in order to get a rough prediction of when another hazard may occur
alerts can then be sent out on smart phones to warn people that a tectonic event will soon occur, which can reduce the number of casualties
Wealth
Advanced Countries (AC)
expensive / high-tech aseismic buildings
strong safety glass to stop windows from breaking
gas pipes automatically shut off
deep foundations
ACs have more resources to cope with the aftermath of tectonic events
Low-Income Developing Countries (LIDC)
LIDCs have less resources to cope with the aftermath, which results in more deaths
low cost aseismic buildings
simple foundations
made of lightweight materials, so people won't be crushed if they collapse
cross-braced wood or bamboo in the walls
Population
low populated / rural areas
less people in an area usually means that less people will die in that area. However people in rural areas could become stranded if the transport links to them are destroyed during the tectonic event, and if this happens they won't be able to get help.
highly populated areas / cities
if there are more people in an area, there are likely to be more deaths in that area
buildings in cities are both bigger and closer together than those in rural areas, so if buildings collapse they are more likely to fall onto people
