NOTE:

Records 9-15 were provided by the Survey of India and its National Institute of Oceanography. Interpretations of these datasets may be found in the following paper: Nagarajan et al., Earth Planets Space, 58, 211-215, 2006. (I am not requiring you to read this paper.) Each of these plots shows 24 hours of data beginning at midnight 26 December 2004 UTC. The Survey of India thoughtfully provides station coordinates in decimal degrees, so you won't have to convert these positions.
