What the record says
NCEI’s account, from the sources it cites.
June 19, 1930, 20:00 [local time]. Two strong shocks at 20 minute intervals in the region of Telukbetung were felt as far as Djakarta (Batqvia) (radius of perceptibility 300 km). There was no damage, but the residents in the vicinity of Telukbetung were terrified and ran screaming from their huts. The captain of a motor boat, tied up at a small moorage at Telukbetung, related that during calm weather with a smooth water surface, a roarlike remote artillery fire was heard. The ship began to vibrate extremely strongly 2 seconds later. In another 2 seconds, the water fell 1/2 m (2 feet), but then rose 1-1 1/2 m (4 feet); a strong ripple appeared on the surface of the sea. The roar and rocking recurred about 20 minutes later and again at 23:50 and 0:08. (reference #414)
