§ 9. Commander BELLAIRS
asked the First Lord of the Admiralty whether any revision of charts has been made of an extensive character as the result of recent earthquakes: and, if so, where?
§ The FIRST LORD of the ADMIRALTY (Sir Austen Chamberlain)
No changes in depths resulting from recent earthquakes in England have been found by His Majesty's surveying ships working round the coasts. Certain minor changes in depths in deep water beyond the Continental Shelf off Nova Scotia as a result of the earthquake of the 18th November, 1929, have been reported by telegraph cable ships and these depths have been embodied in the appropriate Admiralty charts.
