May 7, 1902 Tsunami: Soufriere Volcano, Saint Vincent and the Grenadines
A tsunami caused by a volcano began at Soufriere Volcano, Saint Vincent and the Grenadines on May 7, 1902. The water rose as high as 1 meters. Its effects were recorded at 6 places in at least 5 countries. It killed 1,680 people, counting the earthquake or eruption that caused it.

What the record says
NCEI’s account, from the sources it cites.
Tsunamis were produced when large mudflows entered the sea from the eruption of Soufriere St. Vincent. Robson and Tomblin (Reference #528) reported, "At its climax, pyroclast flows were emitted and swept down the major valleys leading to the west and east coasts, devastating all in their paths, and causing the death of 1,565 persons."
[...] tsunami-like disturbances of up to 1 meter wave were reported for the harbors of Grenada, Barbados, and Saint Lucia. Although the origin of these waves is not known with certainty, the most likely source could have been pyroclastic flows reaching the sea from violent eruption of Soufriere volcano on St. Vincent. Alternatively, the sea level disturbances could have been generated by a most likely unreported flank failure of Mt Pelee, which was also erupting at the time. (reference #1918 in #2823)
Reference #13722 attributes the tsunami wave to the eruption.
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
