The interaction among the Cocos, Nazca, and Panama plates at the Panama Triple Junction (PTJ) generates diverse seismic sources that remain poorly characterized. Using data from the National Seismological Network of Costa Rica and the Chirinet network of Panama, we analyzed four recent earthquake sequences (Mw 5.6–6.2, 2019–2021) near the Burica Peninsula and relocated 32 significant events (Mw 5.6–6.7) that occurred between 2000 and 2025. The results reveal: (1) right-lateral strike-slip faulting along the Panama and Balboa fracture zones; (2) right-lateral faulting on their inland projections, including the 2019 Mw 6.0 Canoas Fault earthquake; (3) reverse faulting during the 2008 (Mw 5.6) and 2020 (Mw 5.6) North Burica sequences, associated with the Media Fault Zone of the upper Panama Plate; (4) left-lateral strike-slip faulting within the subducting Cocos Plate, where at least five Mw 5.8–6.5 events occurred between 2002 and 2019; and (5) a seismogenic Cocos–Panama interplate zone extending southeast of the Burica Peninsula. We further reinterpret the 1934 Ms. 7.6 Armuelles tsunamigenic earthquake as a large megathrust rupture on this interplate boundary. Together, these findings refine the geometry of the seismic sources near the PTJ improving our understanding of the tectonic processes shaping the region.

The northward growth and expansion of the Shanxi rift system (SRS) are key to understanding the geodynamic evolution of the northeastern Ordos block. Previous studies have suggested that Shanxi rift activity weakens north of the Daihai–Huangqihai Basin under the influence of the EW-strike Zhangjiakou–Bohai tectonic zone. In this study, remote sensing and field investigations reveal an ∼100 km long prominent linear structure north of the Jining Basin in the northeastern Ordos block. Three high-density electrical resistivity tomography (ERT) profiles across this structure identify this region as the North Jining Basin Fault, NE-striking, SW-dipping normal fault that structurally controls the northern margin of the basin, exhibiting typical fault depression characteristics and latest activity in the Holocene. Geological evidence confirms that the fault offsets mid-Holocene sediments with a vertical displacement of ∼2.7 m. Combined with the spatiotemporal evolution of the Shanxi rift system, these findings suggest that the northeastern boundary of the rift remains active and continues to propagate northward, with the North Jining Basin Fault representing northward expansion of the extensional regime of the Shanxi rift.
