This research was conducted in order to assess the 1-week aid needs determined by the health professional who voluntarily served in the WhatsApp communication network during the earthquakes in Kahramanmaraş, Turkey.

This descriptive retrospective epidemiological study focuses on the 1-week messaging activities of the WhatsApp group created by volunteers after the earthquake in Turkey. During the 7-day period included in the research, a total of 5813 messages were sent. 3472 of these messages were not included in the research for various reasons, and a total of 2341 messages were used for the research.

In all 7 days, it was seen that most of the messages were sent via text message and that voice messages were very few. When the distribution of the needs demanded by the earthquake victims for 7 days was examined, it was seen that there was a significant increase in the needs on the fourth day after the earthquake, and that the highest increase was the need for tents.

While the demands for rescue services increased in the first 2 days, it was determined that the demands for water especially, dry food, and tents increased from the third day onwards. It is suggested that a professional online infrastructure system should be created to enable the transfer of instant scene and need information that can be activated in such disasters.
