Public warning with feedback
Lack of effective public warning system with the ability to verify whether the information reached the recipient.
Early warning is critical when it comes to minimise the number of casualties and limit the consequences of the (preventing cascading events). The improvement of prediction capabilities (early warning information needs to be more understandable by responders and/or public) and the improvement of the dissemination of alerts, notably to reach vulnerable groups are two main aspects in this regard. The use of social media to monitor the population reaction to an alert, and to some extent check the reception of the information using sentiment analysis or reality mining can provide useful information regarding the attitude of people.
References in the literature: there are gaps identified in the literature about early warning systems and the to alert vulnerable groups, but nothing was found regarding the verification of the reception of the message by the target audience.
