To perform a search, you will need to specify the period and provide the coordinates. It makes it a lot easier to browse the collected data, while also supporting continuous monitoring of a certain area. The service can be accessed using a web form, but an open-source desktop application is also available – Earthquake Bulletin. Authors are permitted and encouraged to post their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work (See The Effect of Open Access).The GEOFON Program of the GFZ Potsdam Research Center for Geosciences was created to provide quick earthquake information from around the world using an extensive network of seismic stations.

The similarity of the focal mechanisms for repeated earthquakes is shown. The focal mechanisms and types of faults are determined by using this method for 6 events occurred in the Transcarpathian region. A sequence of plotting diagrams for determining the focal mechanism is presented. This method is based on identifying the best location option of nodal planes relatively to both the fuzzy P-wave arrivals and the values of the logarithm of the ratio of the S-wave amplitude to the P-wave amplitude. ![]() On the example of several events occurred in the Carpathian region of Ukraine, the solving of this problem with a graphic method is proposed.
