Summary: This study investigates the influence of tidal triggering on aftershocks following the 2011 Tohoku earthquake. It found that the aftershocks were triggered by short-period tides and that the mainshock rupture likely resulted in a critical stress state, facilitating tidal triggering.

Summary: Recent studies have shown that tidal triggering of earthquakes is more likely to occur when the crustal medium is near a critical state, and tidal stresses can be used to forecast earthquakes. Research conducted near the Gaoligong Shear Zone found statistically significant correlations between tidally induced stresses and earthquake times approximately two years before the 2011 Tengchong Mw 5.1 and 5.0 earthquakes.

Summary: The earthquake potential of the Shumagin seismic gap along the Alaska Peninsula has been debated for over 40 years. In July 2020, an M-W 7.8 earthquake occurred in the eastern half of the gap, predicting rupture area and extending westward, with aftershocks concentrating westward in the first month after the mainshock.

Summary: Over the past two decades, space geodesy has greatly improved the study of large megathrust earthquakes by accurately mapping rupture areas, slip distribution, and seismic coupling. By modeling gravity gradients and comparing them with coseismic slip models, we have identified mass heterogeneities and their relationship with seismic activity. This research suggests that combining geodetic and seismological data can help identify and monitor areas with higher seismic hazard potential worldwide.

Summary: This study investigates the dynamic triggering phenomenon in the mainland region of Gujarat, India by analyzing the local earthquake catalog and waveforms. The researchers identify several triggered microearthquakes and observe a delayed triggering event after the mainshock. The study highlights the importance of understanding dynamic triggering in high-seismicity regions.

Summary: The study presents evidence of coseismic land-level change resulting from the 2016 Chiloe earthquake in tidal wetlands along the southern coastline of Isla de Chiloe, Chile. While the creation threshold for land-level change was exceeded, the preservation threshold was not, leading to the lack of preserved records of coseismic land-level motion. Additionally, after nine months, interseismic and coseismic changes were statistically indistinguishable.

Summary: In this study, the earthquake return period was calculated based on statistical approaches and the properties of plate convergence at Java Trench. The results revealed that the southern Middle Java has a relatively fast recurrence of large earthquakes, while the megathrust south of West Java has the potential for a large earthquake indicated by seismic gaps.
