To qualify for the SSS calamity loan, you must be an active member of the Social Security System and have made at least 36 monthly contributions, with 12 of these made in the last 18 months. You need to provide valid identification and proof of the calamity that affected your area, such as a declaration from local authorities. It's also important to ensure that your loan balance is not over the limit set by SSS.
