Drought will affect almost every aspect of human life. The impact of drought hazards is often slow but certain, so that if not monitored continuously it will result in the loss of food due to crops and dead livestock, farmers losing their livelihoods and others. Lamongan regency is one of districts with drought level in very high risk class. At IRBI BNPB in 2011, Lamongan Regency is 2nd ranked of all regencies in Indonesia. By interpreting remote sensing data we will be obtained parameters such as ground surface temperature, vegetation density with EVI transformation, wetness index, brightness index, and land use. These parameters and accompanied by secondary data which is rainfall can be used to identify the drought potential in Lamongan because each parameter has properties that can be associated with its vulnerability to drought potential. Performed by weighting technique and overlay process on these parameters can produce the identified areas with very high drought potential which is 14.171 hectares or 0.009% of total area and dominated in Paciran Sub-District. And the identified areas with very low drought potential which is 20979.626 hectares with a percentage 13.222% of total area and dominated in Karangbinangun Sub-District, Kalitengah Sub-District, Turi Sub-District and Deket Sub-District.
