Manipur lies in a seismically active zone, with a history of major earthquakes, minor tremors, and volcanic eruptions.

The state is located in the eastern Himalayas, which is a region of active tectonic plate boundaries. The Indian Plate is colliding with the Eurasian Plate, and this collision is causing the Himalayas to rise. The movement of these plates also causes earthquakes.

Manipur has experienced several major earthquakes in the past, including the 1897 Manipur earthquake, which had a magnitude of 7.9. This earthquake caused widespread damage and loss of life.

The state also experiences minor tremors on a regular basis. These tremors are usually not harmful, but they can be a nuisance.

In addition to earthquakes, Manipur has also experienced volcanic eruptions in the past. The most recent eruption was in 1825. This eruption caused significant damage to the surrounding area.

Overall, Manipur is a seismically active zone with a history of major earthquakes, minor tremors, and volcanic eruptions. Residents of the state should be aware of the risks and take precautions to protect themselves from these natural hazards.
