“…For this reason, the fractal dimension of earthquakes has widely been used as an effective tool to investigate the seismic hazard for different regions of the earth in recent years (e.g., Matcharashvili et al 2000;Öncel, Wilson 2004;Chen et al 2006;Pailoplee, Choowong 2014;Öztürk 2018;Telesca, Chen 2019). These studies suggest that evaluation of fractal behaviours of earthquake distribution may be correlated with the seismogenic stress situations during seismic activity and may be related to the next earthquake hazard (Gnyp 2007). Another scaling law of earthquake distributions can be given as the Gutenberg-Richter (G-R) frequency-magnitude relation (Gutenberg, Richter 1944).…”

The main objective of this work is to make detailed region-time-magnitude analyses by describing the statistical behaviours of earthquakes in the Central Anatolian Region of Turkey. In this scope, several seismic and tectonic parameters such as Mcomp, b-value, Dc-value, Z-value, recurrence times and annual probabilities were evaluated. For the analyses, a homogeneous catalogue including 10,146 earthquakes with 1.0 ≤ Md ≤ 5.7 between 30 July 1975 and 29 December 2018 was used and spatio-temporal changes of earthquake behaviours were mapped for the beginning of 2019. Earthquake magnitudes varied from 1.9 to 3.0 on average, and hence Mcomp was considered to be 2.6. The b-value was calculated as 1.26 ± 0.07, and this relatively large value indicates that small-magnitude events are dominant. The Dc-value was computed as 1.31 ± 0.03. This small value means that distances between epicentres approach the diameter of the cluster, and seismic activity is more clustered at smaller scales or in larger regions. The spatio-temporal analyses of recurrence times suggest that the Central Anatolian Region has an intermediate/long-term earthquake hazard in comparison to occurrences of strong earthquakes in the short term. Several anomaly regions of a small b-value and a large Z-value were found in and around the Tuzgölü Fault Zone, Central Anatolian Fault Zone, Salanda fault and Niğde fault at the beginning of 2019. Thus, a combination of the regions with a lower b-value, a higher Z-value and also moderate recurrence times may give significant clues for the future possible earthquakes, and detected regions may be thought to be the most likely areas for strong/large events in the Central Anatolian Region.

The criterion of similarity of waveforms at the same station is suggested for identification of quarry blasts conducted on regular basis at local extraction cites of Carpathian region of Ukraine. Case study is presented of the identification of quarry blasts from epicentral area of Dovhe-Irshava, conducted there during 2005–2007. The conclusion has been drawn that the criterion is effective and applicable for removing the quarry blasts from catalogues of local earthquakes.
