Step 1
The chosen geological hazard is the earthquake. The factors that influence the occurrence of an earthquake are fault movement, volcanism, and induced seismicity. The compressional or tensional stresses on the margins of moving lithospheric plates that make the earth's surface cause earthquakes. A sudden release of stress along a fault or fracture is the most ...

How an organization prepares for a vulnerability survey/assessment, and what is risk, and what is vulnerability.

1. How does an organization prepare for a vulnerability survey/assessment? To reduce the risk that a negative event will occur within a system or an organization is to quantitatively reduce the chance by assessing for any or all that could go wrong.

2. What is a risk, and what is vulnerability?

Risk and vulnerability assessment helps to identify people, property, and resources that are at risk of injury, damage, or loss from a number of negative occurences; such as hazards, incidents, sabotage, natural disasters, human error, equipment error, etc. To reduce the risk that a negative event will occur within a system or an organization is to quantitatively reduce the chance by assessing for any or all that could go wrong. This information is important to help determine and prioritize the precautionary measures that can make any system or organization more disaster-resistant. Risk is the chance that it will happen, and vulnerability is the weakness that might cause it to occur. Therefore, you assess to determine the vulnerability and reduce the risk, which makes your organization stronger and more disaster-resistant.
