2023 Uttarakhand Tunnel Collapse
On 12 November 2023, a section of the Silkyara Bend–Barkot tunnel, planned to connect National Highway 134 in the Uttarkashi district of Uttarakhand, India, caved in while under construction. The collapse occurred at around 05:30 IST and trapped 41 workers inside the tunnel. Rescue operations were immediately launched, with a number of government agencies involved, including the National Disaster Response Force, the State Disaster Response Force, Uttarakhand Police, engineers from the Indian Army Corps of Engineers, and Project Shivalik of the Border Roads Organisation. Numerous private resources were utilized in the rescue efforts as well, including Australian tunnelling experts Arnold Dix and Chris Cooper.

Fault (geology)
In geology, a fault is a Fracture (geology), planar fracture or discontinuity in a volume of Rock (geology), rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust (geology), crust result from the action of Plate tectonics, plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction, subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the Plane (geometry), plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone ...
