Regarding magnitude of these types of events, NOAA does amazing work collecting data on tsunami events with impressive energy simulations. As some point I had seen several videos from the Chile event in 2010 that showed the shockwaves traveling around the earth multiple times, but I can't seem to find those videos now. Here's a link to one of the videos with an energy plot from the Chile event - https://nctr.pmel.noaa.gov/chile20100227/20100227Chile.mov https://nctr.pmel.noaa.gov/chile20100227/20100227Chile.mov And the specific Chile event page - https://nctr.pmel.noaa.gov/chile20100227/weblink.html https://nctr.pmel.noaa.gov/chile20100227/weblink.html If you browse around the site, there is a lot of information for many of the largest earthquake/tsunami events in recent times.
