Modifying The Event Flashcards
Divert Lava Flows
SUCCESS:
-Mt Etna lava diverted with explosions + natural barriers
-Delayed flow a month so allowed people to evac
-Prevented economic/social damage
FAILURES:
-Mauna Loa Hawaii explosives used but had no effect
-Flowed towards settlements causing social + econ damage
OVERALL UNSUCCESSFUL:
-Highly viscous so easily break through barriers
-High temp takes too much water to cool + harden
-Path hard to predict
Hazard Resistant Buildings
SUCCESS:
-Mori Tower, Tokyo has shock absorbers to minimise swaying
-Withstands 200+ mag one or more earthquakes a year
FAILURES:
-Sichuan 7000 aseismic buildings collapsed due to rapid construction to try and cope with rapid population growth
-1000s added deaths due to collapsing buildings
OVERALL SUCCESSFUL:
-Very successful if constructed properly
