There's a Coral Sea tsunami station located at 14.803 S 153.585 E (14°48'9" S 153°35'6" E), and it's been in "event mode" ever since the large earthquakes recently occurred in the area. Apparently, the buoy is being triggered by anomalous water column height above the sea floor, and the data seems to show that the ocean floor beneath the buoy is rising at the alarming rate of thirteen feet per day.

The location is also close to the Vanuatu Islands, which have been abruptly volcanically hyperactive for several months now.
