I tried the new version of Content Translation, translating en:1936 Cansiglio earthquake > it:Terremoto del Cansiglio del 1936.
worked well: importing references (even if CT still doesn't recognize dates/months)
Didn’t work: impossibile to import the template:infobox_earthquake; if there is a note, I can't select the entire phrase (I can select only from the beginning to the note); wikidata was not upgraded with the new page translated
