The availability of seismic data has doubled and tripled recently, here, we conduct receiver function study using reliable dense seismic data from BMKG seismic network (IA) to obtain more detail Moho depth variation in Kalimatan and Sulawesi.

The receiver function signals of each seismic station were computed using the iterative time-domain deconvolution method, then the Moho depths and bulk composition (Vp/Vs ratio) were computed using the modified H-κ stacking method which consider the sediment thickness. Our results show that the crustal thickness in Kalimantan varies from ~25 to ~37 km and Vp/Vs ratio varies from ~1.61 to ~1.96, which reflect a characteristic of stable Mesozoic-Cenozoic regions, while Sulawesi is observed within broad thickness range of ~22 – 50 km and Vp/Vs ratio of ~1.56 – 1.97.

Studying key parameters of tectonic structures, including quantitative analysis and observational studies, in such active regions is essential to identify potential active faults and assess the consequent seismic hazards. This study focuses on seismicity and seismotectonics by analyzing seismic parameters, including b-value, mean seismic activity rate, earthquake recurrence time, seismic moment, and fractal dimension derived from micro and teleseismic data. The b-values vary between 0.6 and 1.1 in the tectonically active parts of the study area, corresponding with the reverse/thrust and strike-slip active faults. Large earthquakes might be prone to occur at 10–25 km depth because both catalogues show low b-values (b < 1.0) concentrations at this depth range. The high fractal dimension (> 1.5), high seismic activity rate, large seismic moment parameters, and its continuously increasing trend. Short recurrence periods (20–50 years) of M 6.5 events also emphasize the high seismic activity and high seismic hazard. On the other hand, the prevalence of low b-values is notably observed in areas encompassing densely populated cities such as Rasht, Lahijan, Amol, Babol, Sari, Behshahr, Gorgan, and the megacity of Tehran. Furthermore, we have identified asperities where the Gorgan Plain, the Khazar, and the Alamutrud Fault Zones are located. These findings emphasize the seismic hazard potential in the identified areas and urban centers within the study area. Therefore, particular attention should be directed towards areas exhibiting low b-values when assessing and mitigating seismic hazards.

A network of seven short-period seismic stations was installed in the Al-Refaei district to monitor seismic activity, a project that was initiated in 2014 and continued until 2018. The short-period seismic stations supplement the broadband seismic stations of the Mesopotamian Seismological Network (MPSN), which also serves this area. During the monitoring period, more than 56 earthquakes were recorded, of which 31 were detected by the short-period seismic stations and not reported by any other local or international seismic observatories. Data from the short-period and broadband seismic stations were analyzed using Geiger’s least-squares method to determine accurate locations. The relocated earthquakes delineate a possible fault source with a northwest-southeast trend. The possible fault is not related to any known or previously studied fault. 3D seismic data of the area were evaluated and further supported the interpretation of a northwest-southeast trending fault, named the Al-Refaei fault. Integration of the seismological and 3D seismic data suggests that the Al-Refaei fault is a reverse fault with a S62˚E strike direction and a 43˚ dip angle.

We evaluate the recoverability of seismic waveforms with different clipped levels through artificial clipping experiments and compare the recovery waveforms with the projection onto convex sets (POCS) method. The results show that the restoration deviation of the cubic spline interpolation method is less than 1% at the clipped point, for the records whose clipped amplitude does not exceed 50% of the peak. In addition, the restored phase feature of the cubic spline interpolation is closer to the real waveform than the POCS method. To verify the performance of this method in the realistic earthquake, we apply it to the Barkam Mw 5.9 earthquake. The results show that the peak ratio of the restored clipping records to the measured non-clipping records is close to 1, and the relative error of the response spectrum is less than 0.1.

Data processing using a single seismic sensor is difficult, but using waveforms and spectral-temporal analysis of P, S, and surface waves, it is possible to separate shallow earthquakes from glacial events. We distinguish two types of icequakes—glacier-related events and pulses. An increase in seismic background noise is related to processes of glacial nature in summertime. Data processing allows to obtain the main peculiarities of local seismicity, i.e., mutual connection of glacial processes and crustal seismicity. We show the presence of icequakes induced by local crustal events; their epicenters confined to the ice domes edges. Spatio-temporal sequence and the rate of events migration show that the glacial events are a result of the defusing deformations process in the glaciers caused by the impact of shallow tectonic earthquakes. Thousands of pulsed and high-frequency micro-oscillations associate with the sea ice sheet or lake ice. The temporal variation of events’ number and energy per day correlates with air temperature temporal variations. Moreover, there is a sharp increase in the number of pulses with sharp temperature changes.

The study finds that τc and Pd have a significant correlation with magnitude when separate correlations are developed for site classes C and D.
