GCSE Geography | Immediate and Long-term Responses to Tectonic Hazards (Tectonic Hazards 9)

After a tectonic hazard occurs immediate and long-term responses help the recovery effort - but these may differ between countries at different stages of economic development.

Immediate responses

Immediate responses are the aid and assistance that are given within the first few hours or days following a disaster. These are often referred to as the emergency responses, and they are vital in reducing the death toll, particularly in low income countries.

Immediate responses include evacuating people following a warning, although this is mainly limited to volcanic eruptions as earthquakes occur without warning. They also include the search and rescue effort, trying to rescue people trapped under rubble for example, as well as using social media to aid search and rescue operations. In addition, they include medical care for the sick and injured, this might by in the form of checking people for broken bones, administering pain killers or antibiotics, or performing emergency surgery. Furthermore, they also include providing temporary shelter for those who have lost their homes, usually in the form of large community buildings. Finally providing food and clean bottled water is an important part of the immediate response effort as food and water supplies are often destroyed in a hazard event. The main aim of immediate responses are to minimize the loss of life. Usually in low income countries the victims are dependent on support from high income countries, so emergency aid may take a few days to come through, which is one of the reasons the death toll in LIC events tends to be higher.

Long-term responses

Long-term responses are those that take place in the weeks and months after a hazard event, and focus on the re-building and reconstruction of areas that have suffered extensive damage. The aim is to help people return to their normal lives as quickly as possible, and to also reduce the risk of damage from natural hazards in the future.

Long-term responses include restoring essential utilities that have been affected by the tectonic hazard event, for example repairing gas mains and electricity cables, to ensure that energy sources are restored, as well as repairing water pipes to make sure that people are not without a supply of drinking water for too long. Buildings have to be repaired or rebuilt – both domestic and commercial properties, but also there is the repair of transport infrastructure too, including roads and railways – this is extremely important as damaged infrastructure makes it very difficult to bring in emergency supplies. This process is very costly so can take years to happen in LICs. Another response is working to rehome people who are living in temporary accommodation. In 2021 Haiti was hit by a large earthquake – many of the people affected were still living in temporary accommodation following the devastating earthquake of 2010.

Finally, long-term responses also include putting measures in place to minimize future risk of damage or loss of life, through monitoring, prediction, protection and planning.
