**3. The Kraljevo earthquake**

The earthquake occurred on November 3, 2010, near Kraljevo. It had a magnitude of 5.4, according to the Richter scale. We received a yearbook from our Sarajevo colleagues and at the end of the yearbook, under the foreign works cited, we found a paper in which the results of measurements after the Kraljevo earthquake were published. Later, we also received standardized measurements published in foreign literature.

#### **Figure 3.**

*Daily changes in the side distance between the AGROS permanent stations are presented in quadrangle with diagonals around Kraljevo. Almost all the sides were slightly decreased 2 days before the earthquake, while the sides E, D, and I on the quadrangle, which were further away from what was to be the epicenter of the earthquake shows no significant daily changes in distances [4].*

In our analysis of Kraljevo earthquake, we used an elongated quadrangle with diagonals with reference stations in the AGROS network (**Figure 3**).

We calculated the lengths of the sides and the daily changes of lengths and diagonals in Excel and graphically presented them in **Figure 3**.
