  • The Siji River flows into Assam, where it is known as the Gai River.
  • District authorities have issued alerts for Likabali town and villages along the riverbanks.
  • Precautionary measures include advising residents to avoid riverbanks and evacuate low-lying, flood-prone areas.
  • Heavy rainfall is identified as the primary trigger for the landslide.
