Detailed Description

Water level and barometric pressure graphs from a NOAA tide gauge station in Mayagüez, Puerto Rico, on 15 January 2022. They show a meteotsunami wave about 10 centimeters (4 inches) high at 16:00 GMT, minutes after a spike in barometric pressure that marked the arrival of the first atmospheric wave. For reference, the first big explosion in Tonga occurred at about 04:15 a.m. GMT, nearly 12 hours before the first atmospheric wave reached Puerto Rico.
