Information released by the National Center for Seismology showed the locations of the earthquake epicentres in Arunachal Pradesh. However, no immediate reports of casualties, injuries or significant property damage were mentioned. Authorities had also not announced any major disruption to transportation, communication or essential services following the tremors.
The repeated earthquakes are likely to keep local authorities and residents alert for possible aftershocks. The impact of an earthquake depends on several factors, including its magnitude, depth, distance from populated areas and the strength of nearby buildings. Smaller tremors may be felt locally without causing serious structural damage.
Residents in affected areas should follow official updates and avoid relying on unverified information circulating online. During an earthquake, people indoors should protect themselves from falling objects and stay away from windows, while those outside should move away from buildings, trees and electricity lines. Officials may issue further information after assessing the affected locations.
