Additionally, Table 3 contained errors, where the columns ‘Column’, ‘Lower tephra’, ‘Age Ma’, ‘Upper tephra’, ‘Age Ma’, ‘Thickness between tepras cm’, ‘Rate mm/year (loam fluvial)’, ‘Loam thickness (maximum) cm’ and ‘Terrace gravel age Ma’ were omitted. The correct and incorrect tables appear below.

Incorrect:

Furthermore, the caption of Table 3 was incomplete.

“Table 3. Estimation of sedimentation rates, tephra ages, and terrace gravel ages (= terrace emergent ages). See references in main text.”

now reads:

“Table 3. Estimation of sedimentation rates, tephra ages, and terrace gravel ages (= terrace emergent ages). See references in main text. Significance of bold-italic values: Rate mm/year for loam; significance of underlined values: Rate mm/year for fluvial; significance of bold values: Adopted terrace gravel age Ma.”

The original Article has been corrected.
