Which mechanism causes increased coastal erosion rates following a large earthquake?

💡 Explanation

Tectonic uplift after an earthquake causes rebound along the coast, steeply increasing gradients; therefore, wave action and runoff sharply erode the new, unstable coast, because uplift directly exposes previously submerged land, rather than climate factors or reduced activity.
