At Uttarakhand's "sinking town" of Joshimath, where more than 700 homes have developed cracks and residents are being moved to safety, banned drilling activity has resumed in the dead of night. At 2 am early Wednesday, an NDTV team caught on camera stone-crushing and drilling in full swing in the mountains just outside Joshimath, near the highway that connects the area to the holy town of Badrinath.
