Weirder than that after some digging.
No earth spells work in the following room, in the center of the Lava Drake area.
[Arthelun Ruins, Courtyard]
A massive black marble plinth dominates this area, largely intact, if empty. The bits of floor visible despite the ash and dust are deeply scarred and gouged, the mosaic here almost completely destroyed.
You also see a lava drake and an enormous fiery fissure.
Obvious paths: north, northeast, southeast, south, southwest, northwest.
The rest of the rooms seem fine.
