Is there any information on the height of waves near New Zealand resulting from today's M 8.1 Kermadec Islands earthquake? The video in this tweet shows the small wave produced at Tokomaru Bay in New Zealand following the  M 8.1 - Kermadec Islands, New Zealand 2021-03-04 19:28:31 (UTC) event. These are so far the only thing I've seen in terms of &quot;data&quot; on waves produced by the quake.
Warnings went out and people did rapidly evacuate low elevation coastal areas as a precaution.
Question: Are there any potential measurements of any transient sea-level changes via buoys or perhaps even satellite (e.g. radar, laser), either likely very small ones out at sea or larger ones nearby the coast where the height would be amplified?
Or is all information going to be basically anecdotal?
The data doesn't necessarily have to be available yet, I'm just curious about what measurement capability exists.
Norfolk Island experienced a tsunami wave 64 cm tall. In Australia the tsunami wave was 10 cm at Tweed Heads and 9 cm at Port Kembla. In Vanuatu the height was 32 cm and in Fiji 13 cm  and 8 cm in Tonga.
