1. What is the primary formula used to evaluate Disaster Risk?
Risk=Hazard+Weather+Speed Risk=Sensor+siren+computers Risk=Hazard*Exposure*Vulnerability Risk=Population*Distance*Time
2. If a major flood occurs in an entirely uninhabited area where no people or buildings exist, is it classified as a disaster?
Yes, because any large amount of water automatically constitutes a disaster. No, because disasters can only be triggered by earthquakes Yes, because that weather events are always disasters No, because there are no human or material losses and local coping capacity is not overwhelmed.
3. What is the main objective of an Early Warning System (EWS)?
To provide timely and actionable information to reduce disaster risks. To calculate the financial cost of a disaster after it has already finished. To stop natural hazards like heavy rain from happening entirely. To replace all human volunteers with robotic rescue teams.
4. Effective early warning systems must be designed around which key focus?
They must use the most expensive computers available. They must keep all warning data completely secret from the public. They must be strongly people-centered. They must operate without any regional weather models.
5. In the 'SENSE' framework, how does an upstream river gauge provide 'lead time' to a downstream village?
Data moves faster than the physical floodwaters. The sensor changes the chemical composition of the river. The sensor physically blocks the water from moving downstream. Data is only delivered after the flood has fully passed the village.
6. What does a 'Decision Support System' (DSS) do during the 'DECIDE' phase?
It measures groundwater pressure using underground tools. It automatically builds physical stone walls along riverbanks. It analyzes hazard data and vulnerability profiles to help authorities choose the best action. It turns off all communication networks during an emergency.
7. Which international standard format is used by these systems for emergency alerting and public warnings?
Global Rain Index (GRI) Internet Explorer Format (IEF) Common Alerting Protocol (CAP) Manual Gong Procedure (MGP)
8. What makes an Electronic Siren more versatile than an old Electromechanical Siren?
It can only produce a single, fixed mechanical sound pattern. It strictly requires a person to hit it manually with a stick. It can play pre-recorded or live voice messages in local languages. It cannot run on batteries or solar power.
9. In the Alert Nepal personal alerts portal, what happens if you activate the 'AEWNS Auto Trigger' option?
The alert is permanently blocked and never sent out. The siren sounds immediately when a threshold is met, without waiting for manual human confirmation. It forces you to download a brand new operating system for your mobile device. The system completely deletes your account to prevent false alerts.
