Calm Earth

You infuse the area with powerful protections against earthquakes and upheaval. The area affected cannot be harmed by the effects of an earthquake or volcano (either natural or magical) and remains stable even during the height of such an event in the area. Collateral damage, such as structures tumbling into the area from beyond its limits, or clouds of hot ash or bombs of molten rock falling from above can still damage creatures in the area. The spell does divert lava flows that would normally enter the area along the ground during a volcanic eruption.

At Higher level. When you cast this spell using a spell slot of 8th level the area of effect increase to 1000 ft. When you cast this spell using a spell slot of 9th level the area of effect increase to 1 mile.
