The Indian town of Joshimath, known as a gateway to the Himalayas, sank by 5.4cm, sometime between late December and early January, the Indian space agency has reported. The popular tourist destination, at an altitude of over 6,000 ft (1800 meters), is prone to subsidence, partially due to infrastructure development.
A report by the Indian Space Research Organisation (ISRO) released on Wednesday detailed changes detected by satellite observation of Joshimath, revealing that a rapid subsidence event had taken place sometime between December 27, 2022 and January 8, 2023.
The region's chief minister, Pushkar Singh Dhami, ordered a mass evacuation after a 603 buildings in the town were found to have deep cracks.

A 'Very rare' whale found dead, stranded near Mississippi Gulf Coast
The endangered species is now being examined by several scientists from federal and state agencies, including the Institute for Marine Mammal Studies, Mote Marine Laboratory, FWC Marine Mammal Research and Rescue, and many more.
Crews arrived early to start collecting samples that will determine the cause of death.
"We are doing an external review of the animal, but we will also be looking internally at all the organs and collecting samples to send them off for testing," IMMS stranding coordinator Theresa Madrigal said.

The location of permanent and temporary seismic instruments deployed across the southeast part of the Island of Hawai‘i. Shaded white areas show dense regions of earthquakes interpreted as the Pāhala sill complex. Dashed white box outlines a region of sparsely spaced volcano-tectonic earthquakes that lie between the Kīlauea summit and Pāhala.
These frequent earthquakes occur deep beneath the Pāhala region at approximately 20 to 40 km (12 to 25 miles) depth. Larger events are regularly felt by residents living both within Pāhala and across the island.
In a 2015 study, scientists at USGS located and classified earthquakes in this region into two main groups.
A more continuous seismic tremor, a type of signal often used to trace the movement of magma within a volcanic system, was identified at approximately 40 km (25 miles) depth, both on- and off-shore of the Pāhala region. This activity was interpreted as the migration of magma from the deep Hawaiian hot spot to more shallow depths.
The 5-year-old boy was killed when a tree fell on a vehicle in Butts County, central Georgia, FOX5 Atlanta's Eric Perry reported Thursday night. The adult in the car was taken to the hospital with serious injuries.

Lori Goldsmid, of Brigantine, takes pictures of an approximately 20-foot long humpback that washed ashore in the North end Brigantine Friday, Jan. 13, 2022.
The humpback whale, the resident said, washed up at a beach in Brigantine.
"This was at the far north end of Brigantine," said Connie Pyatt, who noted that the whale was dead.
The dead whale washed up just miles from where another whale was found in Atlantic City on Saturday — which itself washed up blocks away from where another humpback whale was found in December.
Hull Pot, one of England's largest natural holes, was swamped with surging water as storms rolled through the Yorkshire dales on Tuesday (10 January).
Runner Brian Stallwood, who filmed the clip, said he was shocked to find the cascade had disappeared, quipping: "Lake' Hull Pot this evening - who nicked the waterfall?"
Hull Pot, which measures 300ft (91m) long by 60ft (18m) wide, sits on the western side of Pen-y-ghent, one of the mountains that feature in the famed 'three peaks' challenge.

According to the National Weather Service, waterspouts like the one in the video are called tornadic waterspouts, and are essentially tornadoes that form over water during storms like the recent atmospheric rivers that pounded Northern California, though they are rare for the region.
