IHE Notes: Preparation of Earthquakes

Preparation of Earthquakes
1. Building designs & locations
a. Fault lines should be shown on maps for people to avoid constructing buildings above active fault lines
b. If not, foundation of buildings must be extended to solid material c. High-risk areas should have low-density land use
d. Steel structures built to prevent buildings from collapsing when the ground moves i. Taipei 101 has a steel pendulum that would sway & reduce resonance amplification during an earthquake
ii. Tokyo’s buildings reinforced to withstand stronger earthquakes e. Shock-absorbing rubber blocks installed in buildings to absorb earthquake energy & oscillations
f. Electric supplies installed in buildings in Japan & San Francisco with auto shutoffs to prevent fires
g. Fireproof materials used in fittings of buildings to reduce intensity of fires BUT
h. Developing countries may not be as well prepared as Developed countries i. Quite costly for the whole nation to have earthquake resistant features j. Less Developed Countries would have less money for such investment k. Over-congested cities would be a death-trap during an earthquake i. Kobe has many areas with flimsy & old structures which collapsed during the Earthquake

ii. Many buildings & infrastructures collapsed in Sichuan 2008 due to corruption iii. To save cost & time, materials used to build schools were low quality, resulting in collapse of the buildings
iv. Haiti had no reinforced buildings & the govt building collapsed during the earthquake too
2. Drills/ Education
a. In Japan, annual drills are conducted to prepare & educate the population b. Warning systems such as SMS were used to warn the Japanese of impending disasters c. Data collected from constant monitoring of areas in the cities helped to save many lives d. Japan invested thousands of dollars in seismographs and data collection systems to monitor the ocean & ground movements

BUT
e. Some cities/countries do not have...
