  abstract = {{T}he current terrestrial impact crater record includes 188 accepted structures (http://www.passc.net/{E}arth{I}mpact{D}atabase and {F}erriere et al., 2015). {T}his number continues to increase slowly but quite regularly. {T}he heterogeneous distribution of impact structures is strongly influenced by the knowledge about impact cratering of exploration geologists, who have to be familiar with the possible field evidence for impact structures - and ultimately with the recognition criteria accepted for confirmation of new impact structures. {F}or remote and poorly explored areas, satellite imagery is a powerful tool to identify circular structures that, at all scales, could be considered possible candidates for impact structures. {H}ere, we present the results of a first systematic survey of circular structures over the {M}oroccan surface area (a total of 710,850 km(2)) using the imagery available through the {G}oogle-{E}arth software. {S}tructures whose origins could not be elucidated from available geological data were then visited to determine their origin (impact or non-impact). {T}hirteen sites with one or more circular structures were investigated but none of them could be associated with an impact event. {I}nstead, our results illustrate the diversity of geological processes that can produce circular structures, including magmatic and tectonic processes, bioconstruction, and even anthropogenic activity. {I}t also demonstrates that circular structures are very common in surface imagery of the {E}arth but are generally not associated with impact events. {T}his result questions whether this simple approach for the search of impact structures should be extended to other parts of the world. {I}t also emphasizes that remote sensing imagery should not be used in isolation of other data.},
