receiving a disaster location and a disaster time;

determining a target area based on the received disaster location;

determining a plurality of target persons located within the determined target area;

predicting the location of each target person within the determined plurality of target persons based on a plurality of historical movement data associated with each target person within the plurality of target persons;

determining a plurality of filtered persons based on the predicted location of each target person within the plurality of target persons and the received disaster time, wherein determining the plurality of filtered persons based on the predicted location of each target person within the plurality of target persons and the received disaster time comprises the plurality of target persons remaining after removing a plurality of unaffected persons from the plurality of target persons based on determining that the predicted location of each unaffected person within the plurality of unaffected persons is outside a risk area and wherein the risk area is affected by the disaster event;

determining a plurality of safe persons based on the plurality of filtered persons and a safety indicator; and

sending a safety notification to a plurality of concerned contacts associated with each safe person within the determined plurality of safe persons.

2. The computer system of claim 1 , further comprising:

blocking a plurality of network traffic associated with each safe person within the determined plurality of safe persons for a time period following the disaster time.

3. The computer system of claim 1 , wherein receiving the disaster location and the disaster time comprises querying a social networking site for the disaster location and the disaster time or configuring the social networking site to send the disaster location and the disaster time in response to the disaster event.

4. The computer system of claim 1 , wherein determining the target area comprises identifying a geographic area containing the received disaster location and a plurality of areas surrounding the received disaster location.

5. The computer system of claim 1 , wherein the plurality of target persons comprises a personal identifier and an address associated with each target person within the plurality of target persons.

6. The computer system of claim 5 , wherein determining the plurality of target persons located within the determined target area comprises determining if the address associated with each target person within the plurality of target persons is within the target area.

7. A computer program product for reducing load on a mobile network after the occurrence of a disaster event, comprising:

one or more computer-readable storage medium and program instructions stored on at least one of the one or more tangible storage medium, the program instructions executable by a processor, the program instructions comprising:

program instructions to receive a disaster location and a disaster time;

program instructions to determine a target area based on the received disaster location;

program instructions to determine a plurality of target persons located within the determined target area;

program instructions to predict the location of each target person within the determined plurality of target persons based on a plurality of historical movement data associated with each target person within the plurality of target persons;

program instructions to determine a plurality of filtered persons based on the predicted location of each target person within the plurality of target persons and the received disaster time, wherein determining the plurality of filtered persons based on the predicted location of each target person within the plurality of target persons and the received disaster time comprises the plurality of target persons remaining after removing a plurality of unaffected persons from the plurality of target persons based on determining that the predicted location of each unaffected person within the plurality of unaffected persons is outside a risk area and wherein the risk area is affected by the disaster event;

program instructions to determine a plurality of safe persons based on the plurality of filtered persons and a safety indicator; and

program instructions to send a safety notification to a plurality of concerned contacts associated with each safe person within the determined plurality of safe persons.

8. The computer program product of claim 7 , further comprising:

program instructions to block a plurality of network traffic associated with each safe person within the determined plurality of safe persons for a time period following the disaster time.

9. The computer program product of claim 7 , wherein receiving the disaster location and the disaster time comprises querying a social networking site for the disaster location and the disaster time or configuring the social networking site to send the disaster location and the disaster time in response to the disaster event.
