Tonga was locked down really tight (no Covid at all I believe) so, yes, locals might have been out fishing but no leisure sailors. Also it was the middle of the night when the eruption happened so less likely that people were out in very small boats. I've been through a Tsunami while at sea (Galapagos 2010 after major quake in Chile) and because we were in deep water never felt or saw a thing!

Yep, still in the gloomy UK. Had to delay our next trip to Spain until mid-February. Ferry from Portsmouth to Santander then a very pleasant 8 hour drive across the high plain to our house. Go through the Rioja region, past Pamplona, Zaragoza and Valencia.
