Surge earthquake activity 2023 Almora fault activation - Greater Kashmir

"Alarming increase in earthquake activity in the Himalayan region, particularly Nepal and India, triggers government response and proactive measures."

The year 2023 has seen a significant increase in earthquake activity, particularly due to the activation of the Almora fault in Western Nepal. This activation has led to several mainshock earthquakes, with magnitudes of 5.8, 6.2, and 6.4 occurring on January 24, October 3, and November 3, respectively. These mainshocks, along with subsequent aftershocks, have resulted in a higher frequency of earthquakes throughout the year, while the background seismicity has remained unchanged.

Union Minister of Earth Sciences, Kiren Rijiju, shared this information in a written reply in the Lok Sabha, emphasizing the government's commitment to addressing the challenges posed by heightened earthquake activity. The focus is on preparedness and proactive measures to mitigate the impact on vulnerable regions.

The Himalayan region, including Nepal and the northern part of India, is no stranger to moderate earthquakes due to active faults in the area. These fluctuations in seismic activity are a result of collision tectonics, as the Indian plate subducts beneath the Eurasian Plate.

To address the seismic vulnerability of the region, the Bureau of Indian Standards (BIS) has issued the Seismic Zoning Map of India, categorized from Zone II to V. This map serves as a guide for implementing essential engineering codes and practices to ensure the construction of earthquake-resistant buildings.

In response to the increased seismic activity, the National Disaster Management Authority (NDMA) has taken various precautionary measures, including earthquake drills, awareness programs, and comprehensive earthquake management strategies aimed at enhancing preparedness and response to seismic incidents. The government is committed to addressing the challenges posed by heightened earthquake activity and is focused on proactive measures to mitigate the impact on vulnerable regions.
