In this paper, an attempt is to closer describe earthquakes which happened in Nepal in the year 2015. The attention is particularly focused on causes and consequences of these earthquakes and their magnitude, intensity and activity. We introduce with the seismic activity in the area of Himalayas and earthquakes which appear, but also with the characteristics of earthquakes in general. By the collision of two tectonic plates which is happening in the past tens of millions of years, because of the convergence and collision of Indian plate with Euroasian, on the area of Himalayas appear very significant earthquakes. From the earthquakes which happened in Nepal in the last year, the most attention is given to two of them. First important earthquake occured on April 25 near the town Khudi, with the magnitude of 7.8. The second one occured on May 12 by the border area of Kodari, with the magnitude of 7.3. It is realized that earthquakes are interconnected and the probability of their occurrence can be predicted. By this fact, the wish is to be prepared for seismic actions and to prevent the great number of human fatalities and material damages.
