- Abstract
In their 2022 study, Byrne and Krishnamoorthy (https://doi.org/10.1029/2021je007040) extrapolated to Venus the most comprehensive record of eruptions on Earth, to estimate the frequency of volcanic events on the second planet. The approach underlying this extrapolation is necessarily based on assumptions for which there is little supporting evidence; moreover, the eruptive record on Earth is far from complete because, for example, submarine events are considerably undercounted. Byrne and Krishnamoorthy (2022, https://doi.org/10.1029/2021je007040) discussed at length the limitations of their study, cautioning that their estimates on the frequency of volcanic eruptions on Venus are simply that—estimates, albeit amenable to testing by future missions to the planet. The comment by van Zelst on the Byrne and Krishnamoorthy (2022, https://doi.org/10.1029/2021je007040) study identified a calculation error in one specific scenario considered in that earlier study. The other points raised in the van Zelst comment are either consistent with the range of uncertainties discussed in, or focus on topics that have no bearing on, the Byrne and Krishnamoorthy (2022, https://doi.org/10.1029/2021je007040) study. The scientific conclusions of the Byrne and Krishnamoorthy study remain unchanged. Plain Language Summary: Although there are strong hints of active volcanism on Venus, how often volcanoes erupt there is wholly unknown. In their 2022 study, Byrne and Krishnamoorthy made a first attempt to estimate how common volcanic eruptions are on Venus by taking the best record of eruptions on Earth and applying it to Venus. van Zelst (2022b, https://doi.org/10.1029/2022JE007448) wrote a comment in response to the study by Byrne and Krishnamoorthy, pointing out that those authors made a mistake in their calculation for one of the possibilities they considered. The comment by van Zelst made several other points, but none changes the overall conclusions of the study by Byrne and Krishnamoorthy. The bottom line is that the only way to be really see how often volcanoes erupt on Venus is to send spacecraft there. Key Points: The comment by van Zelst on Byrne and Krishnamoorthy (2022, https://doi.org/10.1029/2021je007040) identifies a single calculation errorThe overall conclusions of that 2022 study either remain unchanged by or are unrelated entirely to the van Zelst comment
