88. May 23. 



This earthquake recorded by the " Discovery " apparently refers to the one recorded in Manila by the 

 Vicintini seismograph. It originated in the island of Mindanao (see Earthquake No. 48), near to Darao 

 and Caraga, at the head waters of the Rio Augusan (see 'Bulletin Philipp. Weather Bureau,' May, 1903, 

 p. 115). Westwards across Europe and Asia the disturbance extended to Great Britain, 105 distant, but 

 it does not appear to have reached Victoria, B.C., or Cape Town, respectively distant 95 and 105 along 

 paths which would be suboceanic. The area covered closely resembles that for Nos. 73 or 88. The first 

 entries for Perth, Mauritius, Batavia, and that for Kodaikanal refer to a distinct shock which may or may 

 not be related to the one noted by the " Discovery." 



The Manila record indicates the time of origin at a distance of 14 as 22h. 7m. The entries for M at 

 Batavia, Perth, and Calcutta respectively give 22h. 7m., 22h. 6m., and 22h. 5m. as the times for the origin. 

 The following table is constructed on the assumption that the time of origin was 22h. 7m. :
