On August 11, 2012, two successive strong earthquakes (Mw = 6.4 and 6.3) hit the East Azerbaijan Province, NW Iran at 12:23 and 12:34 UTC. This study investigated the variations of multi earthquakes precursors, (Land Surface Temperature (LST), Total Electron Content (TEC), Outgoing Longwave Radiation (OLR), and Air Temperature (AT) of non-seismic phenomena before and after the successive Ahar (Iran) earthquakes. In this study, we used the moving median method to detect the anomalies in TEC, whereas ±2σ (95% confidence level) interval was used in MODIS LST and OLR analyses as an anomaly indicator. The results indicated that the MODIS Nighttime LST decreased by 5.5–6.3 °C compared to the mean (LST) within 10–12 days before the earthquakes Then a dramatic increase was observed on August 02, 2012. The LST results were consistent with the results of OLR, where the anomaly was observed on July 29, 2012. In addition to LST and OLR, significant TEC anomalous disturbances (increase and decrease) occurred two weeks before the earthquakes started on 28th July and reached the highest value 3 days before the earthquakes. Furthermore, AT analysis also provided identical results with LST behaviors. These results were instructive for seismologists and represent the importance of the corresponding potential precursors for upcoming earthquakes.

2012年8月11日，世界标准时间12:23和12:34，连续两次发生强烈地震（Mw = 6.4和6.3）袭击了伊朗西北部的东阿塞拜疆省。这项研究调查了多次地震前兆（陆面温度（LST），总电子含量（TEC），呼出的长波辐射（OLR）和空气温度（AT）的非地震现象在连续Ahar之前和之后的变化（在本研究中，我们使用移动中值法检测TEC中的异常，而MODIS LST和OLR分析中使用±2σ（95％置信水平）区间作为异常指标。与地震发生前10-12天内的平均值（LST）相比，夜间LST降低了5.5–6.3°C。然后，在2012年8月2日，观测到的LST急剧增加。LST的结果与OLR的结果一致，在2012年7月29日观测到异常。除了LST和OLR，在7月28日地震开始并到达地震前两周，还发生了严重的TEC异常扰动（增大和减小）。地震前3天的最高值。此外，AT分析还提供了与LST行为相同的结果。这些结果对地震学家具有指导意义，并代表了相应潜在前兆对于即将发生的地震的重要性。AT分析还提供了与LST行为相同的结果。这些结果对地震学家具有指导意义，并代表了相应潜在前兆对于即将发生的地震的重要性。AT分析还提供了与LST行为相同的结果。这些结果对地震学家具有指导意义，并代表了相应潜在前兆对于即将发生的地震的重要性。
