  abstract = {{S}hallow hydrothermal vents are of pivotal relevance for ocean biogeochemical cycles, including seawater dissolved heavy metals and trace elements as well as the carbonate system balance. {T}he {K}ueishan {T}ao ({KST}) stratovolcano off {T}aiwan is associated with numerous hydrothermal vents emitting warm sulfur-rich fluids at so-called {W}hite {V}ents ({WV}) and {Y}ellow {V}ent ({YV}) that impact the surrounding seawater masses and habitats. {T}he morphological and biogeochemical consequences caused by a {M}5.8 earthquake and a {C}5 typhoon ("{N}epartak") hitting {KST} (12th {M}ay, and 2nd-10th {J}uly, 2016) were studied within a 10-year time series (2009-2018) combining aerial drone imagery, technical diving, and hydrographic surveys. {T}he catastrophic disturbances triggered landslides that reshaped the shoreline, burying the seabed and, as a consequence, native sulfur accretions that were abundant on the seafloor disappeared. {A} significant reduction in venting activity and fluid flow was observed at the high-temperature {YV}. {D}issolved {I}norganic {C}arbon ({DIC}) maxima in surrounding seawater reached 3000-5000 µmol kg-1, and {T}otal {A}lkalinity ({TA}) drawdowns were below 1500-1000 µmol kg-1 lasting for one year. {A} strong decrease and, in some cases, depletion of dissolved elements ({C}d, {B}a, {T}l, {P}b, {F}e, {C}u, {A}s) including {M}g and {C}l in seawater from shallow depths to the open ocean followed the disturbance, with a recovery of {M}g and {C}l to pre-disturbance concentrations in 2018. {T}he {WV} and {YV} benthic megafauna exhibited mixed responses in their skeleton {M}g:{C}a and {S}r:{C}a ratios, not always following directions of seawater chemical changes. {O}ver 70% of the organisms increased skeleton {M}g:{C}a ratio during rising {DIC} (higher {CO}2) despite decreasing seawater {M}g:{C}a ratios showing a high level of resilience. {KST} benthic organisms have historically co-existed with such events providing them ecological advantages under extreme conditions. {T}he sudden and catastrophic changes observed at the {KST} site profoundly reshaped biogeochemical processes in shallow and offshore waters for one year, but they remained transient in nature, with a possible recovery of the system within two years.},
