These systems and methods may include receiving a plurality of emergency communications from a corresponding plurality of user devices, determining an emergency location based on locations of the plurality of user devices based on the plurality of emergency communications, and determining whether the plurality of emergency communications at the emergency location exceed a threshold number of emergency communications. Proximate user devices may be identified, and an alert may be sent to at least one of the proximate user devices. ## Claims ### Claim 1 A method performed by an emergency service system comprising: receiving, at a processor of the emergency service system, a plurality of emergency communications from a corresponding plurality of user devices; determining an emergency location based on locations of the plurality of user devices based on the plurality of emergency communications; determining whether the plurality of emergency communications at the emergency location exceed a threshold number of emergency communications; and identifying proximate user devices within a predefined proximity of the emergency location based on collected location signals associated with the proximate user devices; sending, in response to determining that the threshold number of emergency communications has been exceeded, an alert to at least one of the proximate user devices that did not provide one of the plurality of emergency communications. ### Claim 2 (depends on 1) The method of claim 1, further comprising determining a type of alert based on the plurality of emergency communications, the alert having the type. ### Claim 3 (depends on 1) The method of claim 1, wherein the plurality of emergency communications include at least one text message and at least one phone call. ### Claim 4 (depends on 1) The method of claim 1, wherein sending the alert includes sending the alert to at least one device not among the plurality of user devices based on a location of the at least one device corresponding to the emergency location. ### Claim 5 (depends on 1) The method of claim 1, further comprising refraining from sending the alert to at least one other user device of the plurality of user devices based on the at least one other user device not being in or near the emergency location. ### Claim 6 (depends on 1) The method of claim 1, wherein sending the alert includes sending the alert to all of the plurality of user devices. ### Claim 7 (depends on 1) The method of claim 1, wherein sending the alert includes sending the alert to all of the proximate user devices. ### Claim 8 (depends on 1) The method of claim 1, wherein the proximate user devices are identified directly from the proximate user devices themselves or through a server based on respective IP addresses of the proximate user devices. ### Claim 9 A device for providing emergency service-related information, the device comprising: one or more hardware processors; a memory, storing instructions, which when executed, cause the one or more hardware processors to perform operations comprising: receiving a plurality of emergency communications from a corresponding plurality of user devices; determining an emergency location based on locations of the plurality of user devices based on the plurality of emergency communications; determining whether the plurality of emergency communications at the emergency location exceed a threshold number of emergency communications; and identifying proximate user devices within a predefined proximity of the emergency location based on collected location signals associated with the proximate user devices; sending, in response to determining that the threshold number of emergency communications has been exceeded, an alert to at least one of the proximate user devices that did not provide one of the plurality of emergency communications. ### Claim 10 (depends on 9) The mobile device of claim 9, wherein the one or more hardware processors are further configured to perform operations comprising determining a type of alert based on the plurality of emergency communications, the alert having the type. ### Claim 11 (depends on 9) The mobile device of claim 9, wherein the plurality of emergency communications include at least one text message and at least one phone call. ### Claim 12 (depends on 9) The mobile device of claim 9, wherein sending the alert includes sending the alert to at least one device not among the plurality of user devices based on a location of the at least one device corresponding to the emergency location. ### Claim 13 (depends on 9) The mobile device of claim 9, wherein the one or more hardware processors are further configured to perform operations comprising refraining from sending the alert to at least one other user device of the plurality of user devices based on the at least one other user device not being in or near the emergency location. ### Claim 14 (depends on 9) The mobile device of claim 9, wherein sending the alert includes sending the alert to all of the plurality of user devices. ### Claim 15 (depends on 9) The mobile device of claim 9, wherein sending the alert includes sending the alert to all of the proximate user devices. ### Claim 16 (depends on 9) The mobile device of claim 9, wherein the proximate user devices are identified directly from the proximate user devices themselves or through a server based on respective IP addresses of the proximate user devices. ### Claim 17 An apparatus for providing emergency service-related information, the apparatus comprising: means for receiving a plurality of emergency communications from a corresponding plurality of user devices; means for determining an emergency location based on locations of the plurality of user devices based on the plurality of emergency communications; means for determining whether the plurality of emergency communications at the emergency location exceed a threshold number of emergency communications; and means for identifying proximate user devices within a predefined proximity of the emergency location based on collected location signals associated with the proximate user devices; means for sending, in response to determining that the threshold number of emergency communications has been exceeded, an alert to at least one of the proximate user devices that did not provide one of the plurality of emergency communications. ### Claim 18 (depends on 17) The apparatus of claim 17, further comprising means for determining a type of alert based on the plurality of emergency communications, the alert having the type. ### Claim 19 (depends on 17) The apparatus of claim 17, wherein the plurality of emergency communications include at least one text message and at least one phone call. ### Claim 20 (depends on 17) The apparatus of claim 17, wherein the means for sending the alert include means for sending the alert to at least one device not among the plurality of user devices based on a location of the at least one device corresponding to the emergency location.
