Discerning Structure and Seismic Hazards in the Sikkim Himalayas A dense seismic network in operation since 2019 will provide new insights into the tectonics of seismically active Himalayan regions. Kanchenjunga, the third-highest mountain in the world, is seen here from the Tshoka basecamp near seismic station SK23.

For the past 120 million years, since India and Africa began to split apart (leaving Madagascar in between), the tectonic plate on which India sits has been moving northward. This relentless movement, along with the region’s complex geological structure, eventually led to the formation of the towering Himalayas.
