H= Hazard V= Vulnerability of population
C to C= Capacity to Cope
A hazard is a perceived natural event which has the potential to threaten life and property. Most hazards are dormant or potential, with only a theoretical risk of harm; however, once a hazard becomes "active", it can create an emergency situation. A hazardous situation that has come to pass is called an incident. Hazard and vulnerability interact together to create risk. A cause of a hazard can be both natural and man-made. A natural hazard is caused by a natural process e.g. two plates rubbing together and causing an earthquake, a man-made is caused by human activity e.g. adding to global warming. A disaster is a hazard becoming reality in an event that causes deaths and damage to goods and property is a natural or man-made or technological hazard resulting in an event of substantial extent causing significant physical damage or destruction, loss of life, or drastic change to the environment. It is a phenomenon that can cause damage to life and property and destroy the economic, social and cultural life of people. A cause of a disaster can be both natural and man-made.

R = M or F of H x V Tectonic hazards are events caused by the Tectonic plates below the Earth's crust colliding with each other, moving against each other or moving apart. These plates are platforms of rock that move on the convection currents created by the earth’s core. E.g. Earthquakes, Volcanoes and Tsunami's. So the hazard is the actual event happening but the tectonic disaster is the aftermath left after the hazard happening so how they can support the money lost through the disaster by replenishing buildings and cities with them being damaged by earthquake’s, volcanoes and tsunami’s. Linked to volcanoes there are some terms needed one of these are a lahar and this is a type of mudflow or debris flow composed of pyroclastic material, rocky debris, and water. The material flows down from a volcano, typically along a river valley. With higher income countries such as Japan, New Zealand and Italy it doesn’t always mean that they can respond as quickly as other income countries (upper middle, lower middle and low income countries). But generally speaking high income countries have faster responses due to their money and the connections they have to help them get out of trouble from a tectonic hazard and disaster. So in Italy in 2009 an earthquake hit L’Aquila and other towns in the centre of Italy it reached 6.3 in magnitude, leaving 308 people dead and 3,000-10,000 building damaged. With this event happening field hospitals were set up to help local medical services. But with this many people still had to be treated in the open with the lack of facilities with them being destroyed. Also with this phone and power lines were damaged and...
