People injured and killed.
Ports, bridges,roads and railways destroyed.
Pipes(water and gas) and electric cables broken
Secondary effects of an earthquake
Business reduced and money spent repairing damage,which slows the economy.
Blocked transport infrastructure hinders emergency services and prevents aid.

Burst water pipes lead to a lack of clean water and poor sanitation, increasing the spread of diseases.
Primary effects of a volcanic eruption
Property and farms destroyed. People and livestock injured and killed. This is due to lava flows and ash collapsing buildings.
Air travel halted due to airborne volcanic ash damaging engines.
Water supplies contaminated.
Secondary effects of a volcano
The economy slows. Emergency services struggle to a arrive.
Ice melts,causing flooding. Flood water or rain mixes with volcanic ash, causing mudflows destroying property and killing people.
Tourism increases with those interested in visiting volcanoes
The ash breaks down, forming fertile land for farming.
Immediate responses to tectonic hazards.
Warnings are issued Rescue teams search for survivors Treatment given to those injured Shelter,food and drink is provided Bodies are recovered Fires are extinguished
Long term responses
Repair and rebuild properties and transport links.
Improve building regulations
Utilities are restored
Locals are resettled elsewhere
Opportunities are developed for the recovering economy
