The 1956 Anjar earthquake occurred at 15:32 UTC on 21 July, causing maximum damage in town of Anjar in Kutch, Gujarat, India. It had an estimated magnitude of 6.1 on the surface wave magnitude scale and a maximum perceived intensity of IX on the Mercalli intensity scale.[2]
The epicenter of earthquake of 21 July 1956 was at somewhere between Anjar and Bhadresar,[3] very close to that of 1819 Kutch earthquake, between 50 and 120 km away depending on the epicentral location chosen for the earlier event. It caused considerable damage and casualties, especially in and around town of Anjar, India. The area of maximum damage was of 2000 km2 and radius of perceptibility was 300 km.[4] The cause of earthquake was reverse faulting, similar to that which caused the 1819 earthquake.[5]
The town of Anjar and the Taluka of Anjar were the most affected region with 2000 houses damaged, of which half of them were in Anjar town alone. The other towns affected were Bhuj, Kera, Bhachau, Gandhidham and port town of Kandla.[2] At least 115 people were reported to have died and casualties numbered to 254 as per government records.[4] [6] It was estimated that more than 3,000 houses in 25 villages developed huge cracks, losses ran up to 10 million. Such devastation wreaked by the quake made it one of the worst calamities to hit Kutch in the past 100 years. More than 8,000 people migrated from the district a few days after the quake. The earthquake was followed by heavy rains, which added to the misery of thousands living in temporary camps.[7]
Anjar, which is a historic town and very congested in the old parts was largely destroyed in this earthquake of 1956. Later, new houses were raised on old foundations, and in due course of time also the new township of Naya Anjar or New Anjar township was founded after this earthquake for rehabilitation purpose.[8] [9] [10] The railway track near Anjar was damaged as the earth gave way over a length of nearly 50 feet,[11] however, other major railway lines, roads, bridges, culverts, were not affected by this earthquake.[12]
The next major earthquake in the region was of 26 January 2001, which again was due to a similar style of faulting as the 1819 earthquake.[5]
