One of the hypotheses of mass extinction at the Cretaceous–Paleogene boundary is associated with a sharp increase in the volcanic activity of the Large Igneous Province of Deccan due to the impact of a ten-kilometre asteroid near the Gulf of Mexico [1, 2]. A sudden increase in mantle effective permeability (MEP) initiated by seismic disturbances of the impact was considered in [2] as a cause of the increase in the flow rate of magma. We used an empirical method to estimate the density of… 


Triggering of the largest Deccan eruptions by the Chicxulub impact
New constraints on the timing of the Cretaceous-Paleogene mass extinction and the Chicxulub impact, together with a particularly voluminous and apparently brief eruptive pulse toward the end of the
State shift in Deccan volcanism at the Cretaceous-Paleogene boundary, possibly induced by impact
High-precision dating of Deccan Traps volcanic units suggests an increase in volcanism associated with the Chicxulub impact, which suggests postextinction recovery of marine ecosystems was probably suppressed until after the accelerated volcanism waned.
Impacts do not initiate volcanic eruptions: Eruptions close to the crater
Many papers on meteorite impact suggest that large impacts can induce volcanic eruptions through decompression melting of the underlying rocks. We perform numerical simulations of the impact of an
Antipodal focusing of seismic waves due to large meteorite impacts on Earth
SUMMARY We examine focusing of seismic waves at the antipode of large terrestrial meteorite impacts, using the Chicxulub impact as our case study. Numerical simulations are based on a
Seismic effects from major basin formations on the moon and mercury
Grooved and hilly terrains occur at the antipode of major basins on the Moon (Imbrium, Orientale) and Mercury (Caloris). Such terrains may represent extensive landslides and surface disruption
Hydrologic Responses to Earthquakes and a General Metric
Hydrologic responses to earthquakes, including liquefaction, changes in stream and spring discharge, changes in the properties of groundwater such as geochemistry, temperature and turbidity, changes
Geophysical signatures associated with fluid flow and gas hydrate occurrence in a tectonically quiescent sequence, Qiongdongnan Basin, South China Sea
Interpretation of high-resolution two-dimensional (2D) and three-dimensional (3D) seismic data collected in the Qiongdongnan Basin, South China Sea reveals the presence of polygonal faults,
The Seismic Efficiency of Space Body Impacts
The numerical analysis of the propagation of shock waves initiated by either a space body striking the Earth’s surface, or underground explosions, allows us to compare the energies required to attain
