A volcano-related tsunami produced extraordinary waves at Trinidad, following an explosion of a mud volcano island. (reference #537 and #1917)
Some extraordinary sea waves were noticed on the adjacent coast following an explosion which accompanied the formation of a mud volcano (reference #43)
Following the volcanic explosion of a mud island volcano off Trinidad, "extraordinary waves" were observed. (reference #1492)
