Well that will wake you up twenty minutes before knock off on a Friday, NEMA Emergency Mobile Alert going off on both my work phone and my own phone, as well as every phone in the office with a tsunami warning. There has been a 7.7 magnitude earthquake at the Loyalty Islands, by New Caledonia, that has triggerd a tsunami wave headed our way. There is unlikely to be an actual damaging wave but there are "likely to be strong currents and surges can injure and drown people. There is a danger to swimmers, surfers, people fishing, small boats and anyone in or near the water close to shore".
I sit beside one of our costal engineers so get expert interpretation of events, including getting pointed to the best public domian data. Below is the plot off a DART bouy (Deep-ocean Assessment and Reporting of Tsunami) southwest of New Caledonia. The wave is only about 5" high, tsunami waves aren't very high until they get to shallow water. This bouy, DART NZJ, is moored in water 1,900m/6300' deep. The time on the graph is UTC. On the map the triangles are DART bouys. The white ones are unfortuantely inoperative.
