Frequency distribution of the tidal stress values for the 767 exoplanets from our sample. The dashed red line indicates the threshold when a rocky exoplanet experiences sufficient tidal stress (h > 10^-5) to aid or initiate subduction. For exoplanets without an eccentricity value or where e ~ 0, we use Zanazzi & Triaud (2019) assumption of e = 0.01 ± 0.01 as reasonable for ultra-short period exoplanets.
