چکیده مقاله:
Reviewing seismic activities in East Asia, especially Japan, holds significant importance. This region is known as one of the most seismically active regions in the world and has a history of many destructive earthquakes. In ۲۰۲۲, we have seen an increase in the number of earthquakes compared to a ten_year period from ۲۰۱۳ to ۲۰۲۲, and progress in earthquake monitoring equipment and methods has played an essential role in their more accurate identification. An analysis of moderate to large earthquakes and their spatial distribution shows that ۲۰۲۲ is poised to surpass previous years as the most earthquake active in ten-year period from ۲۰۱۳ to ۲۰۲۲. This intensification of seismic activity has caused significant damage to Japan's infrastructure and security, emphasizing the urgent need for increased public awareness and preparedness measures against such natural disasters. Given the rising earthquake risk, international collaboration for enhancing early warning systems and strengthening infrastructure resilience is of paramount importance. This paper examines the earthquake activities that occurred in ۲۰۲۲. Using comprehensive earthquake statistics, it provides a thorough comparison of the energy released by these earthquakes with major earthquakes in the past seven decades. The purpose of this comparative analysis is to clarify global earthquake patterns and potential trends. By understanding these trends, we can better prepare for future earthquake events and mitigate their devastating consequences.
