Merriam-Webster's website redirects "Earthshattering" to "Earth-shattering"... so I'll go with the majority here.
EDIT: Also, I've reviewed the Trope Namer,"Hare-way To The Stars". Marvin quite clearly puts a slight pause between "Earth" and "shattering", indicating that there was a hyphen in the script.
