Sending Safety-Check Prompts
In one embodiment, a method includes determining that an emergency event has occurred. The method also includes determining a geographic area affected by the emergency event. The method also includes determining that a user has entered the geographic area within a pre-determined amount of time after the occurrence of the emergency event. The method also includes sending a prompt to the user to indicate whether the user is safe. The method also includes receiving from the user a response indicating whether the user is safe.
1 . A method comprising, by one or more computing devices:
determining that an emergency event has occurred;
determining a geographic area affected by the emergency event;
determining that a user has entered the geographic area within a pre-determined amount of time after the occurrence of the emergency event;
sending a prompt to the user to indicate whether the user is safe; and
receiving from the user a response indicating whether the user is safe.
2 . The method of claim 1 , wherein determining that the user has entered the geographic area within the pre-determined amount of time after the occurrence of the emergency event comprises receiving location information from a software application open on and executing in a foreground of a mobile computing device of the user.
3 . The method of claim 1 , wherein the prompt is sent if at least a pre-determined threshold number of users send information associated with the emergency event.
4 . The method of claim 3 , wherein sending information associated with the emergency event comprises sharing on a social-networking system an update associated with the emergency event.
5 . The method of claim 3 , wherein the information is a check-in, text, video, or photograph.
6 . The method of claim 1 , wherein the user is a user of a social-networking system.
7 . The method of claim 1 , wherein the prompt is sent to the user only if at least a predetermined threshold percentage of users in the geographic area or within a predetermined distance of the geographic area have posted content related to the emergency event.
8 . The method of claim 1 , wherein the prompt is sent to the user only if there was at least a predetermined threshold level of engagement by users with a previous safety check associated with the emergency event.
9 . The method of claim 8 , wherein the predetermined threshold level of engagement with the previous safety check comprises:
a predetermined number of users interacting with the previous safety check;
a predetermined number of users ignoring or hiding the previous safety check; or
a predetermined number of impressions of the previous safety check.
10 . The method of claim 1 , further comprising, based on responses to safety prompts associated with the emergency event, determining an update to the geographic area affected by the emergency event.
11 . The method of claim 1 , further comprising:
at a time associated with the emergency event, determining that a second user is currently in the geographic area;
sending a prompt to the second user to indicate whether the user is safe; and
receiving from the second user a response indicating whether the user is safe.
12 . One or more computer-readable non-transitory storage media embodying software that is operable when executed to:
determine that an emergency event has occurred;
determine a geographic area affected by the emergency event;
determine that a user has entered the geographic area within a pre-determined amount of time after the occurrence of the emergency event;
send a prompt to the user to indicate whether the user is safe; and
receive from the user a response indicating whether the user is safe.
13 . The media of claim 12 , wherein determining that the user has entered the geographic area within the pre-determined amount of time after the occurrence of the emergency event comprises receiving location information from a software application open on and executing in a foreground of a mobile computing device of the user.
14 . The media of claim 12 , wherein the prompt is sent if at least a pre-determined threshold number of users send information associated with the emergency event.
15 . The media of claim 14 , wherein sending information associated with the emergency event comprises sharing on a social-networking system an update associated with the emergency event.
16 . The media of claim 14 , wherein the information is a check-in, text, video, or photograph.
17 . A system comprising:
one or more processors; and
one or more computer-readable non-transitory storage media coupled to one or more of the processors and comprising instructions operable when executed by one or more of the processors to cause the system to:
determine that an emergency event has occurred;
determine a geographic area affected by the emergency event;
determine that a user has entered the geographic area within a pre-determined amount of time after the occurrence of the emergency event;
send a prompt to the user to indicate whether the user is safe; and
receive from the user a response indicating whether the user is safe.
18 . The system of claim 17 , wherein determining that the user has entered the geographic area within the pre-determined amount of time after the occurrence of the emergency event comprises receiving location information from a software application open on and executing in a foreground of a mobile computing device of the user.
19 . The system of claim 17 , wherein the prompt is sent if at least a pre-determined threshold number of users send information associated with the emergency event.
20 . The system of claim 19 , wherein sending information associated with the emergency event comprises sharing on a social-networking system an update associated with the emergency event.
