Identify the triggering mechanism of the seismic sequence in Cao Bang (ML=5.0) from November 2019 to May 2020 and assess the seismic hazard caused by the seismic source in the Trung Khanh district, Cao Bang province.

1.    Active tectonic faults map of the Trung Khanh district, Cao Bang, and surrounding areas, scale 1:50,000.
2.    Peak ground acceleration (PGA) and seismic intensity map (I-MSK 64) for the Trung Khanh area, Cao Bang, scale 1:50,000.
3.    Integrated GIS database of the project.
Theoretical results: The research results determining the source parameters of the Cao Bang seismic sequence have provided information on the local stress field, sliding mechanism, and the mechanism causing the Cao Bang seismic sequence.
Applied results: The research results have the potential for application in seismic research, planning, and designing earthquake-resistant structures for the study area.

The research results evaluating the seismic hazard for the Trung Khanh district, Cao Bang province, and nearby areas, taking into account the influence of local site effects and terrain elevation. These are novel research findings that reflect the current state of ground shaking for the study area, with significant implications for planning and disaster prevention and mitigation.

The earthquake in Cao Bang (ML=5.0) highlights the vulnerability of the mountainous provinces in the Northeast region, indicating that this area is susceptible to damage not only from earthquakes within Vietnam's territory but also from seismic events occurring beyond its borders. This underscores the need for conducting research to assess the seismic hazard and zoning for the Northeast region of Vietnam, aiming to minimize potential damage caused by earthquakes in the future.
