What the record says
NCEI’s account, from the sources it cites.
Reference #13558:
Visual observations during 17 September and on the morning of 18 September showed that lava was being extruded quietly, thus producing a large steam cloud, but no large explosions were seen. This explains therefore, why no explosion was detected at the Sofar station which could be correlated with the atmospherics detected at 1503 and 1517 on 17 September.
Four explosions, none of which were of large magnitude, occurred on 17 September. The longest group commenced at 0611 and lasted 15 minutes.
