EARTHQUAKE

Living in earthquake zones presents numerous hazards that can create significant challenges and dangers. One major threat is the possibility of tsunamis, which can travel long distances and cause extensive destruction when they sweep inland, particularly in coastal areas.

Destruction of properties

severe shortage of housing
people will lose their homes
cause widespread destruction to homes

Threat Of Tsunami

Causes widespread destruction at coastal areas when sweep inland
Travel long distances

Landslides

Furthermore, ashen debris flows caused by earthquakes can also trigger mass movement of soil
When earthquakes occur on areas with steep slopes, many times the soil slips causing landslides
E.g. An earthquake hits Ecuador of 6.7-magnitude was particularly deadly for its size due to the major landslides that occurs only 20 mins after the earthquake hit
Landslide
Mass movements of rock, debris, and soil down a slope of land

DISRUPTION OF SERVICES

Communication services are affected
TV broadcasts and telephone connections
Vibrations snap pipes and break cables causing outbreak of fire
Potentially affect a large area
Kobe, Japan in 2004
Disrupt Supply of electricity , gas and water

Fires

Rapture Gas Pipes (providing fuel to start fires)
Ability to spread quickly over large area

Eg. Kobe,Japan,1995-Extensive Fires Raged For 2 Days

Destruction of infrastructure

Japen, Kobe
Places in city become inaccessible or difficult to reach
Transportation can be disrupted
Unsafe to use damaged roads
