Volcanic Activity on Venus: How Long Must We Look to Find a Smoking Gun?

چکیده
Abstract While volcanic landforms attest to the numerous and varied processes on Venus, estimates of frequency eruptions are lacking. Constraints from resurfacing volumes can be equally satisfied by infrequent large or smaller events. Recently, Byrne Krishnamoorthy (2022), https://doi.org/10.1029/2021JE007040 , used 40‐year period 1980 2020 Smithsonian Global Volcanism Program (GVP) database (Global Program, 2013) extrapolate events Earth Venus. They evaluated tectonic settings GVP provided that consider differences in those between extrapolated rate volcanism Venus using mass/volume ratios, freeing their results uncertain evolution The assumption is a stagnant‐lid regime with straight‐forward geodynamic has been challenged Weller Kiefer (2020), https://doi.org/10.1029/2019je005960 who showed planetary surface may reflect different styles convection highly active sluggish inactive regions occurring at same time. scaling allowed estimate as many 120 might take place every year, should detectable upcoming missions.

متن کاملThe Lada Terra rise and Quetzalpetlatl Corona: A region of long-lived mantle upwelling and recent volcanic activity on Venus
Quetzalpetlatl Corona ( 850 km in diameter) and Boala Corona ( 350 km 250 km in diameter), are both situated within the Lada Terra rise, a prominent 2000-km-wide circular topographic feature rising 2.5–3 km above the mean planetary radius in the southern hemisphere of Venus, south of the Lavinia Planitia lowlands. Together these features form a unique configuration that combines the characteris...
متن کاملHow Often Must We Apply Syndrome Measurements?
Quantum error correction requires encoding quantum information into a quantum error correction code and measuring error syndromes to detect and identify possible errors. Quantum fault tolerance typically assumes that syndrome measurements are applied after every logical gate at great expense both in time and number of qubits. Here we demonstrate that not only is this not necessary, but that we ...
متن کاملProtective immunity against tuberculosis: what does it look like and how do we find it?
Progress towards the development of an effective vaccine against tuberculosis is hampered by the lack of correlative readouts of immune protection, coupled with our limited understanding of the immune mechanisms that determine disease progression versus containment. In this article we discuss the value of microbial readouts of bacterial fitness to probe the host immune environments and determin...
