Animation of the 19 May 2023 Loyalty Islands Tsunami

At around 3pm NZDT on Friday 19 May, a M7.7 earthquake occurred about 400 km to the east of Loyalty Islands (800 km south-west of Fiji) causing small tsunami on coasts around the south-west Pacific, and strong currents and surges for New Zealand. We first detected waves reaching our shores on our coastal tsunami gauges at around 5:15pm. This animation shows propagation of the tsunami simulated using a GNS in-house computer (COMCOT model).
