The correct answer is: a) Floods.
Early warning systems are crucial for disaster preparedness in Arunachal Pradesh, especially for floods. Arunachal Pradesh is a state in northeastern India that is prone to floods. The state has experienced several major floods in recent years, including the 2014 flood that affected over 100,000 people and the 2017 flood that affected over 200,000 people.
Early warning systems can help to reduce the impact of floods by providing people with time to evacuate and by allowing authorities to take steps to protect infrastructure. Early warning systems can also help to improve the response to floods by providing information about the location and severity of the flood.
There are a number of different types of early warning systems that can be used for floods. These include:
- Flood forecasting systems that use data from river gauges, rainfall radar, and satellite imagery to predict the likelihood and severity of floods.
- Flood inundation models that use data from topographic maps, river gauges, and rainfall radar to simulate the effects of floods on a particular area.
- Flood warning systems that use sirens, text messages, and other methods to alert people to the threat of a flood.
Early warning systems can be very effective in reducing the impact of floods. However, they are only effective if people are aware of them and if they take action when they are alerted to a flood threat.
The other options are not as important as floods for disaster preparedness in Arunachal Pradesh. Earthquakes are less common in Arunachal Pradesh than in other parts of India. Landslides are a problem in some parts of the state, but they are not as widespread as floods. Droughts are also a problem in some parts of the state, but they are not as severe as floods.
