Effects of earthquakes and volcanoes

One of the regions where people are at greatest risk is the Ring of Fire

​The level of risk depends on the geographical location – areas close to plate boundaries such as those around the Ring of Fir are more at risk than those areas in the middle of tectonic plates.

​Risks and vulnerability

• Areas which are densely populated are more at risk.

• Developing and emerging countries building structures may be less robust and more densely packed together,

Urbanisation

• ​LEDC are less equipped to deal with Natural disasters

• Poorer infrastructure leads to more damage

• Poor health services

• weaker emergency response

• lower levels of planning and preparation

​​Level of economic development

​Primary effects:
- Death
- Injuries
- Damage to crops
- Damage to infrastructure

​ Secondary:
- spread of diseases
- homelessness
- loss of jobs
- food shortages
- transportation issues ( grounded aeroplanes )
- mUDFLOWS

​​- Pyroclastic flow
A fast moving flow of material down the side of a volcano. The flow is a mixture of ash, pumice and hot gases. Very dangerous due to high speed and high temperatures, capable of causing widespread deaths.

​​Caused by :

- Lava flow
- Volcanic bombs from eruption
- toxic gas clouds

​Primary effects:
- Death
- Injuries
- Damage to crops
- Damage to infrastructure
- avalanches
- Tsunamis

​ Secondary:
- spread of diseases
- homelessness
- loss of jobs
- food shortages
- transportation issues
- tsunami
- landslides
- Fires
