What the record says
NCEI’s account, from the sources it cites.
According to BRGM (2013) , who quotes a report of Philosophical Transaction of the Royal Society of London, an eye-witness report that on June 4th at Bonne "...half one hour before the sunset a sudden extraordinary current of the sea happened. In less than a minute the sea water retired and sunk ten feet and upwards. The sea shore become dry more than two hundred paces from its common mark, leaving the fish upon dry land, number of which were taken up; .....Three minutes after, the waters entered again with the same rapidity, with which they ran out; and I observed even till night, that those irregular motion of the sea diminished by degrees; and that, about every two minutes, the waters went in and out alternately, loosing their motion insensibly, like those undulations made by agitating a vessel of water." (reference #11164, v.2)
Note: "BRGM, (2013): Tsunamis observed in France. Bureau de Recherches Geologiques et Minières, www.tsunamis.fr" is cited by ref #11164 but no longer publicly available.
Note: ref #9384 and #9901 discuss an earthquake from Miliana to Bona [Annaba] in 1724. It is possible that report is related/mixed/confused to the reports of this event as little information is available, as noted by ref#9384.
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
