Focusing on human behavioral aspects are significant in the effective delivery of Early Warnings to the community on time. In that context, the extent of trust towards the Multi-Hazard Early Warning mechanism plays a major role. This deals with delivering the warning messages related to several hazard categories and the cascading disaster risks triggered by one hazard striking. Among the stakeholders who are interlinked with this mechanism, first responders play a vital role in disseminating the Early Warnings to the vulnerable community at downstream level. To examine the perception of the first responders, a survey was undertaken and overall 1004 responses were collected. From the indicator calculation of the trust based on the mean score and the sentiment score, the extent of the perception level was determined. This denoted that there exists a lower level perception of trust towards the existing Multi-Hazard Early Warning mechanism. This was revealed with this basis of the content of the message, level of understandability of the message and extent of variation of the immediate response with time towards the warnings delivered on different hazard categories. Further, the correlation determination of experience of the first responders with the number of people with non-varying trust levels was examined through IBM SPSS software. Here, the graphical representation denotes a negative polynomial relationship with r2 value of 0.9. This denoted a strong negative correlation among the two parameters, in which the experience of the first responders was limited to a maximum of 5 years. These results were then compared with the findings of the recent research study that was on community-level assessment of the perception on the existing Multi-Hazard Early Warning mechanism. From the results obtained, it was revealed that the community has a high preference on adapting to Early Warnings delivered through mobile phone while first responders have a lower level of trust on this mechanism.
