Special Issue Information

Dear Colleagues,

In recent decades, multiple regions throughout the world have displayed differing types of active geological structures characterized by high seismic potential, making them particularly vulnerable to the impending possibility of catastrophic earthquake occurrences. Continuous, real-time monitoring of surface seismic activity around the world is of great interest for acquiring new insight into global tomography analyses and for the recognition of seismic patterns leading to potentially hazardous situations. In addition, over the past few years, artificial intelligence has demonstrated its effectiveness as a valuable asset in addressing different seismological challenges, such as earthquake detection and source classification. This contrasts standard methods which require extensive data processing periods or expensive computational resources. Detailed scientific research on seismic activity may provide key constraints related to earthquake generation forecasting and climate change as affected by topography or volcanic processes. Studies relating the physical process of the source, imaging the deep structure and active crustal deformation are helpful in allowing for understanding the mechanism of earthquake generation and modelling the waveform propagation effects, to provide a theoretical basis for reducing earthquake disaster.

This Special Issue aims to highlight advances in the development of new techniques and analytical methods. These can be applied to signal detection, and processing, source characterization and seismic imaging to characterize seismic activity (i.e., detection, location, magnitude and source mechanism estimation, seismic tomography and ambient noise seismology) and emphasize tectonic evolution at various scales within different environments. We encourage methodological contributions as well as key applications, which demonstrate how these new technologies and/or methods help improve our understanding of the physical processes governing earthquakes, as well as the Earth’s architecture.

Earthquakes impact the stability of municipal solid waste (MSW) landfills, especially those with high water levels, and may further lead to disastrous landslides. Numerical analysis offers an efficient and cost-effective way to study the seismic stability of a landfill. In this study, the finite difference nonlinear analysis method was employed to meticulously evaluate the dynamic response of landfills under varying water levels and seismic intensities. The analysis was guided by the seismic instability and centrifuge test outcomes. The rationality of the computational model was verified by examining the responses of acceleration and pore pressure. Subsequently, the time history curve of the dynamic safety factor was derived from the dynamic response of landfills. The results indicated that a landfill was more susceptible to large earthquake effects, and its stability decreased as the water level rose, with the safety factor decreasing to a critical point under the coupling effect of strong earthquakes and high water levels. In contrast, the stability of the landfill with low water levels was good under weak earthquake conditions, with only a slight decrease in the safety factor observed. The seismic stability of a landfill was significantly influenced by both accumulative deformation and negative excess pore pressure. A certain degree of hysteresis in the landfill’s instability was also observed compared to the earthquake loading process. The time history curve of the safety factor can offer a comprehensive insight into seismic stability under diverse conditions. Additionally, future research efforts are needed to better determine the values of strength parameters of MSW in seismic analysis. Full article

The East Kunlun Fault Zone, as a highly seismically active fault, has witnessed five earthquakes with magnitudes exceeding M7.0 to the west of Animaqing Mountain since 1900. Conversely, the historical records for the Maqin–Maqu segment in the east of Animaqing Mountain show no M7.0 or above earthquakes, designating it as a distinctive seismic gap within this fault zone. We analyzed the tectonic background and structural features of the Maqin–Maqu segment within the East Kunlun Fault Zone to evaluate its potential seismic capacity. Utilizing a new established probability recurrence model, we calculated the seismic hazard for both segments over the next 100 years. The results indicate that the probability of M7.0 or above earthquake occurring in the Maqu segment in the next 100 years is 11.47%, classified as a moderate probability event. The joint probability of at least one M7.0 or above strong earthquake occurring in the entire Maqin–Maqu segment in the next 100 years is 16.14%, also classified as a moderate probability event, while the probability for the Maqin segment alone is 5.36%, classified as a low probability event. Considering the uncertainty of the probability model, a qualitative hazard classification for each segment was further conducted. The comprehensive evaluation suggests a low risk of a major earthquake occurring in the Maqin segment in the next 100 years, while the Maqu segment is assessed to have a higher risk. Full article

Seismic networks in urban areas today represent key infrastructure to better address the tasks of earthquake preparation and mitigation in the pre-event phase, and are an important knowledge tool supporting disaster risk management during seismic crises and post-disaster recovery. In the last fifteen years, a decrease in instrumentation costs and the development of new low-cost devices have enhanced the deployment of several monitoring and experimental networks worldwide. This paper conducts a review of scientific work that refer to the deployment of Urban Seismic Networks (USN) in order to define the current state of the art. We collected a list of more than one hundred USNs worldwide that were operative within the period from 1994–2023. For each USN, we report the locations and objectives along with information about the timing, coverage, geometry, and technical characteristics (sensors and transmission). By reviewing all these aspects, this paper offers important insights to provide guidelines for new implementations, bearing in mind that the interest in monitoring urban areas is expected to continue to increase in the near future driven by population growth in urbanized areas.
