Disaster risk is expressed as the likelihood of loss over exposed elements. Direct disaster losses refer to directly quantifiable losses such as the number of people killed and the damage to buildings, infrastructure and natural resources. Indirect disaster losses include declines in output or revenue, and impact on wellbeing of people, and generally arise from disruptions to the flow of goods and services as a result of a disaster. Losses are usually measured over a period, or normalised as Annual Expected Damage (EAD) or Annual Average Losses (AAL).

Loss
The effect of a disaster on people, buildings and society is referred to as the impact. Losses are a measure of the damage or destruction caused by a disaster and may be monetary or non-monetary losses. Direct disaster losses refer to directly quantifiable losses such as the number of people killed and the damage to buildings, infrastructure and natural resources.
Wider impacts include longer-term social and economic effects, for example in education, health, productivity or in the macro economy. Indirect disaster losses include declines in output or revenue, and impact on wellbeing of people, and generally arise from disruptions to the flow of goods and services as a result of a disaster.
The impact of disasters can also generate gains, and not only losses, for some people and economies, for instance the demand for construction material and expertise following a disaster. It is therefore necessary to think of disasters in terms of both impacts and losses.

Economic Loss
Total economic impact that consists of direct economic loss and indirect economic loss. Direct economic loss is the monetary value of total or partial destruction of physical assets existing in the affected area. Direct economic loss is nearly equivalent to physical damage. Indirect economic loss is a decline in economic value added as a consequence of direct economic loss and/or human and environmental impacts.

People affected
People who are affected, either directly or indirectly, by a hazardous event. Directly affected are those who have suffered injury, illness or other health effects; who were evacuated, displaced, relocated or have suffered direct damage to their livelihoods, economic, physical, social, cultural and environmental assets. Indirectly affected are people who have suffered consequences, other than or in addition to direct effects, over time, due to disruption or changes in economy, critical infrastructure, basic services, commerce or work, or social, health and psychological consequences.

I'm not sure we should include the data images here. I see why they're included, but my concern is they focus people too much onto the data without any explanation. Especially showing vulnerability curves without any context of what the chart shows / how to read it. Would prefer this glossary to not include the data images, and save these for the examples section.

Got it. Figures can indeed be moved to example section instead.
Some edits to make the loss definitions quicker and better link the concept of loss with impact - also rephrasing disaster impact definition. Bullet points can be turned into plain text. Suggesting to keep together "loss" with "economic loss": they are all pieces of the same concept, thus repeating same information.

Loss Losses are a measure of this impact in the form of damage or destruction caused by a disaster (observed or modelled). This measure may be expressed as monetary (e.g. cost of reconstruction) or non-monetary (e.g. hectars of crop loss, loss of life). Losses can be direct or indirect.
The total economic impact consists of a monetary estimate of both direct disaster loss and indirect disaster loss.

Impact model An impact model (also damage model; loss model) is used to combine Hazard, Exposure and Vulnerability components to calculate the amount of value that is expected to be damaged or lost. It is used to calculate direct or indirect loss.

People affected People have been exposed and impacted, either directly or indirectly, by a hazardous event. Directly affected are those who have suffered injury, illness or other health effects; who were evacuated, displaced, relocated or have suffered direct damage to their livelihoods, economic, physical, social, cultural and environmental assets. Indirectly affected are people who have suffered consequences, other than or in addition to direct effects, over time, due to disruption or changes in economy, critical infrastructure, basic services, commerce or work, or social, health and psychological consequences.
