In 21st December 2015 between near 13 to 14 o’clock Iran sky you have all the planets plus the moon in the sky. Besides, the moon has the nearest distance to the earth. As the distance is on reduction between the earth and the moon, it seems to me, some earthquakes are producing in the local time I mentioned above, like Mexico recent earthquakes, or other weaker earthquakes. Usually in the higher land near lower land, on not too High Mountain near the coast, as moon makes tiding effects with others. It is up to seismologist to see seismic activity of the region and follow it with attention.
