In one embodiment, a method includes detecting that a first set of users associated with an emergency event have posted content related to the emergency event on an online social network. The method may also include sending a safety-check prompt to each of one or more users in the first set. The method may also include determining a current-prompting probability based on one or more engagement metrics of the one or more users in the first set. The method may also include sending, in response to determining that the current-prompting probability is above a threshold probability, the safety-check prompt to each of a second set of users. The second set of users may have more users than the first set of users.

Sending safety-check prompts based on user interaction

In one embodiment, a method includes identifying an emergency event; determining that a threshold percentage of users who are associated with the emergency event have posted content related to the emergency event to an online social network; sending, in response to the determination, a safety-check prompt to each of a first set of users; determining a current-prompting probability based on one or more engagement metrics of the safety-check prompt by the first set of users; and sending, in response to determining that the current-prompting probability is above a first threshold probability, the safety-check prompt to each of a second set of users, wherein the second set of users comprises more users than the first set of users.
