Tectonic hazards can have many impacts on people and their environment. However, some of these impacts can be reduced by management strategies such as prediction, building techniques, planning and education. These waves travel faster than the other types of waves and cause less damage so they can be used as a warning for stronger tremors. However, even far away from the epicentre the warnings may only arrive a few seconds before the strong tremors.

For example, tiny earthquakes and changes in the shape of the volcano e. Although people died, this figure would've been much higher without the evacuation. Often people don't want to abandon their homes or they don't believe the eruption will really happen. Rainfall and meltwater mix with volcanic ash to create mudflows lahars. Tourism increases with people interested in seeing the impact of the volcanic eruption.

Ash provides fertile soil for agriculture. Related Topics Use the images below to explore related GeoTopics. Topic Home. Next Topic Page.

What factors influence the effects and response to tectonic activity? Rural and Urban areas Population density also affects the impact of an earthquake. Distance from the epicentre The closer the epicentre the stronger the earthquake. Emergency response Lack of emergency services and poor communication links in LICs mean that people are not rescued as quickly, or cared for as well, as they would be in a HIC.

Time of day Night time earthquakes can make it more difficult to rescue people immediately after an earthquake. Time of Year Earthquakes can result in higher fatalities if they occur in times of cold weather.

Surface type The type of soil or rock that an area is built on affects the impact of the earthquake. Related Topics Use the images below to explore related GeoTopics. Previous Topic Page. Topic Home. Next Topic Page. In geography these are often referred to as socio-economic factors.

Poverty is a major issue throughout the world. People with low incomes, or people who rely on support from family members, would find it difficult to better protect themselves and to increase their capacity to cope with a natural disaster.

In some regions of the world, farming is challenging due to poor farming methods, difficult climate and thin soils. It is the people within marginal areas of land who often suffer most during an earthquake because they are unable to afford strong buildings to live in and they often have poor communication links.

It is very difficult for people and services to get into remote and underdeveloped areas affected by natural disasters, if the transport and communications systems are poor.
