Аннотация: Results of the study of macroseismic effects of a remote deep-focus earthquake of May 24, 2013 under the sea of Okhotsk in the territory of Moscow are reported. On the surface of the earth and on the first floors of the buildings the seismic effect was not felt. The effect of the shock began to manifest itself, starting from the fifth floor of the buildings. Distribution of points, where the earthquake was obviously felt on the map is unregular. Not revealed preference points with sensations of shaking with certain types of Quaternary deposits and with the zones of different their thickness. There is also no significant correlation of the parts of the surface with high intensity of shaking and areas of flooding by the ground waters. Comparison of the surface manifestations of seismic event with tectonic features and deep structure of the metropolis was fulfilled. From the results of the produced statistical estimation of distribution points, where the earthquake was felt on the territory of the city is visible, that the fault zones control the larger number of points sensation and block structure characterized by almost half the number of such items. Thus, we can reasonably talk about a certain macroseismic increasing of vibrations from earthquakes in the areas of large faults in the city. The study of deformations of asphalt cover of walkways on landslide slope of Vorobiev's hills showed that shaking caused by Okhotsk sea deep focus earthquake of May 24, 2013, there was a reason of small activation of landslides at all levels of the hillside.
