Hazards & Opportunities
It is estimated that 600 million people will live in seismically active areas by 2025
There are many hazards associated with living in areas vulnerable to earthquakes and volcanic eruptions, as outlined in the previous section
Many opportunities are particularly associated with living near volcanoes, including:
Fertile soil
The ash and cooled lava contain many minerals, which lead to high crop yields
Tourism
Many people want to visit areas where there are active volcanoes; this increases the number of jobs available
Minerals and precious stones
These can be mined and sold, providing work for local people
Geothermal energy
As the magma is closer to the surface, the heat can be used to generate geothermal energy
Creating a new land area
Once the lava and ash have cooled, new land is formed
The opportunities for living in earthquake zones include:
Building regulations and infrastructure
Areas have stricter building regulations to ensure that construction can withstand seismic activity
This can lead to stronger and more resilient buildings and infrastructure
Community preparedness
Residents in earthquake-prone areas tend to be more prepared for natural disasters
This can result in a more resilient and united community that is better equipped to respond to emergencies
Research and innovation
Earthquake-prone areas attract researchers and engineers focused on developing technology and techniques for earthquake prediction, early warning systems, and building strength
This can lead to improvements in earthquake science and engineering that benefit everyone living in active regions
Natural beauty
Some people find the scenery, geological formations, and outdoor leisure opportunities of earthquake-prone areas attractive to live and work in
Some earthquake-prone areas are close to the coast where the climate is good and fishing and farming are easy, such as the San Francisco Bay area
It is important to also remember that some people have little choice but to live in earthquake zones due to limited money, despite the risk of property damage, injury, and disruption to daily life
Worked Example
Fig 1 shows Teide, an active volcano in the Canary Islands
Give three opportunities that volcanoes like Teide offer to people.
