The outburst generated the highest-ever recorded volcanic plume, one reaching 35 miles (57 kilometers) tall, and triggered tsunamis as far away as the Caribbean.

How the Tonga tsunami, generated in the Pacific, succeeded to cross America and reach the Caribbean islands?
Strange. It implies that the wave went around Cape Horn?

Perhaps, atmospheric 710 mph “Lamb waves”, and 600 mph “Gravity waves”, amplified by “Proudman resonance”?

The volcanic eruption in Tonga on 15 January 2022 surprised scientists by triggering two types of tsunamis: “classic” tsunamis caused by the displacement of large volumes of water, and meteotsunamis caused by fast-moving pressure disturbances in the atmosphere.

Meteotsunamis, generated by the eruption’s atmospheric waves, were observed all around the globe. At a tide gauge in Mayagüez, Puerto Rico, a water level change of about 10 centimeters (4 inches) occurred at noon local time, just minutes after a spike in barometric pressure that marked the arrival of the first atmospheric wave.

In the Mediterranean Sea, water levels rose nearly a foot on the coast of Spain, and as much as a foot and a half in the Balearic Islands (an area prone to weather-generated meteotsunamis). Small meteotsunami waves, ranging from a few inches to about a foot high, were also evident on tide gauge records in the Indian Ocean.
