Thanks!
I did this tsunami animation in GMT
can’t remember what projection I used, but it’s not mercator…

Nice. Maybe it’s polar stereographic centred somewhere over the middle of the Pacific? Although normally that would be a circular plot. The top and bottom of your plot is straight ..
i just found the old script, Mollweide, -JW206/6i
The region was dictated by the extents of the data from the NOAA tsunami propagation database.
a tsunami animation would look pretty cool on your projection… I can get you some netcdf files with tsunami max amplitudes across the pacific if you want to try.
I think tsunami maps would be a good application of this projection. The projection was designed to minimise distortion across the whole Pacific - the abstract for the original paper is here: https://onlinelibrary.wiley.com/doi/10.1111/j.1745-7939.1974.tb00757.x
A stereographic projection centred on the middle of the Pacific Ocean would be an easier alternative because it’s built into GMT. But doing the whole thing on the Lee projection wouldn’t be too hard either.
Then again, maybe an equidistant projection centred on the earthquake would be better … then equally spaced concentric circles around the earthquake would roughly indicate arrival times.
