Colaba Observatory became more well known through his examination of geomagnetic measurements at Colaba, and his interpretation of the physics behind the phenomena. After his untimely death in Feb. 1896, the mantle of Directorship fell on the shoulders of Nanabhoy Ardeshir Framji Moos , the first Indian to hold this position.

During periodic dredging operations to maintain the depth of the docking bays, many intact gold bars have been found, some as late as February 2011, and returned to the government. A live shell weighing 45 kg (100 lb) was also found in October 2011. The Mumbai Fire Brigade 's headquarters at Byculla has a memorial to the fire fighters who died. National Fire Safety Week
140-741: A higher degree in Science from Edinburgh in Scotland, Moos saw to the efficient functioning of Colaba Observatory, regular analysis and interpretation of the measurements, and the starting of seismological observations. In 1900 Bombay decided to convert its fleet of horse-drawn trams to electric power for public transport. The electric trams would have vitiated the data from the Colaba magnetic observatory by generating electromagnetic noise. Moos selected an alternative site at Alibag , located about 30 km (19 mi) directly south-east of Bombay. Alibag

The Ghatkopar kitchen was still running when Vile Parle 's Irla residents started running a second centre for about 500 persons, where food and lodging were provided for the refugees. A third kitchen was opened at Khotwadi and Narli Agripada in Santacruz where about 300 people were being served. In Khar , arrangements had been made to give rations to about

In 1846 the East India Company ordered his full atmospheric electricity collecting and measuring apparatus for the observatory. Subsequent superintendents Charles Montriou and Edward Francis Fergusson maintained contact with Ronalds and visited him at Kew for hands-on instruction. It was arranged in 1867 for Kew's photo-recording machines to be supplied so that continuous observation of atmospheric pressure , temperature and geomagnetic intensity could be performed automatically. Charles Chambers (later to become

Its headquarters continued to be in Mumbai, in the building constructed by John Curin in 1826, who was an astronomer for the East India Company. The first Director of the Indian Institute of Geomagnetism over 1971–1979 was B. N. Bhargava. The proceeding Director

Some 80,000 people were made homeless and 71 firemen lost their lives in the aftermath. The ship was carrying a mixed cargo of cotton bales, timber, oil, gold, and ammunition including around 1,400 tons of explosives with an additional 240 tons of torpedoes and weapons. The SS Fort Stikine
525-463: The affected areas began pouring into the suburbs. About six thousand persons from the Mandvi area, mostly middle class, went to Ghatkopar . The workers and others from Ghatkopar got the three schools opened for their accommodation and private households also provided accommodation to these unfortunate families. There was a rush of labourers from the dock areas who wanted to get out of Bombay on foot by
560-414: The area. Around 2 km (0.77 sq mi) were set ablaze in an 800 m (870 yd) arc around the ship. Eleven neighbouring vessels had been sunk or were sinking, and the emergency personnel at the site suffered heavy losses. Attempts to fight the fire were dealt a further blow when the second explosion from the ship swept the area at 16:34. Burning cotton bales fell from the sky on docked ships,
595-418: The cotton bales as probably being the seat of the fire. It was critical of several errors: Many families lost all their belongings and were left with just the clothes on their backs. Thousands became destitute. It was estimated that about 6,000 firms were affected, and 50,000 people lost their jobs. The government took full responsibility for the disaster, and monetary compensation was paid to citizens who made

Some of the most developed and economically important parts of Bombay were wiped out by the blast and resulting fire. The details of the explosions and losses were first reported to the outside world by the Japanese-controlled Radio Saigon, which gave a detailed report of

The crew, dockside fire teams and fireboats were unable to extinguish the conflagration, despite pumping over 900 tons of water into the ship, and nor were they able to find the source due to the dense smoke. The water was boiling all over the ship, due to heat generated by the fire. At 15:50

Apart from these, a temporary station was run in the Andaman Islands in 1974 as support for the ONGC (Oil and Natural Gas Commission of India) in petroleum prospecting. Since 1979, an array of Gough-Reitzel magnetometers has operated at various sites in India for studies of the Earth's internal structure by examining electromagnetic induction within
805-515: The order to abandon ship was given, and sixteen minutes later there was a great explosion, cutting the ship in two and breaking windows over 12 km (7.5 mi) away. This and a later second explosion were powerful enough to be recorded by seismographs at the Colaba Observatory in the city. Sensors recorded that the earth trembled at Shimla , a city over 1,700 km away. The shower of burning material set fire to neighbourhoods in

The recording of geomagnetism and meteorological observations was started at the observatory in 1841 by Arthur Bedford Orlebar, who was then Professor of Astronomy at Bombay’s Elphinstone College . Magnetic measurements between the years of 1841 and 1845 were intermittent; following 1845 they became bi-hourly, then hourly. Sophisticated equipment invented by Francis Ronalds ,

More than 500 civilians lost their lives, many of them residing in adjoining slum areas, but as it was wartime, information about the full extent of the damage was partially censored. The results of the explosion are summarised as follows: D. N. Wandrekar,

The de-watering operation took three months to complete, after which Jackson and Brazier returned to their base in Colombo. Jackson remained in the Far East for another two years, conducting further salvage work. For their efforts with the pumping operation, both men were rewarded: Brazier
945-407: The ship's captain, Alexander James Naismith, recorded his protest about such a "mixture" of cargo. The transportation of cotton through the sea route was inevitable for the merchants, as transporting cotton by rail from Punjab and Sindh to Bombay was banned at that time. Naismith, who lost his life in the explosion, described the cargo as "just about everything that will either burn or blow up." In

Over the year 1919–1971, 17 Directors steered the Colaba-Alibag Observatories through avenues of meticulous and uninterrupted geomagnetic recordings, regular publishing of the data, and discussion of observations in scientific research journals. In 1971 the Colaba-Alibag Observatories were converted into an autonomous research organisation called

Moos retired in 1919 after leading the Colaba-Alibag Observatories to worldwide renown. In 1910 he summarised the main findings from 50 years of geomagnetic measurement at the Colaba-Alibag Observatory over 1846–1905, in two volumes titled "Magnetic observations made at

Ramanathan (a past Director of Colaba-Alibag), strongly advocated the setting up of magnetic observatories to examine the equatorial electrojet . The Trivandrum and Annamalainagar observatories were set up in November 1957, and were tended first under the Directorship of S. L. Malurkar, and then under P. R. Pisharoty. Eighteen years elapsed before there

1120-924: Was a 7,142 gross register ton freighter built in 1942 in Prince Rupert , British Columbia, under a lend-lease agreement; the name Stikine was derived from the Stikine River in British Columbia. Sailing from Birkenhead on 24 February, via Gibraltar , Port Said and Karachi , she arrived at Bombay on 12 April 1944. Her cargo included 1,395 tons of explosives including 238 tons of sensitive "A" explosives , torpedoes , mines , shells, and munitions . She also carried Supermarine Spitfire fighter aircraft, raw cotton bales, barrels of oil , timber , scrap iron and approximately £890,000 of gold bullion in bars in 31 crates.

An Australian minesweeper, HMAS Gawler , landed working parties on 21 June 1944, to assist in the restoration of the port. It took three days to bring the fire under control, and later, 8,000 men toiled for seven months to remove around 500,000 tons of debris and bring the docks back into action. The inquiry into the explosion identified

These aspects were checked out carefully over a 2-year period from 1904–1906, and then only was recording at Colaba discontinued, and the electric tram service started in Bombay. The entire building was made of hand-picked, non-magnetic, Porbandar sandstone, and magnetic recording
