Interesting Felt Report of EMSC after 11/27_M4.3 Algeria event!!! Expressing triggered a "void structure" for N of Medea of this earthquake under big possibility.In the other hand,I observed a felt report after M3.7-S of Lake Aral!!! Expressing triggered a "void structure" of NE of Urgenç of this earthquake event.Also,I summary problematic nature of ground structure as Geophysical of Nukus settlement by distance-felt relation via felt map!
