Size and morphology of the Chicxulub impact crater
The Chicxulub impact in Mexico has been linked to the mass extinction of species at the end of the Cretaceous period. From seismic data collected across the offshore portion of the impact crater, theExpand

Seismic velocity structure of the lunar mantle
I have inverted the recently completed set of seismic arrival times from the Apollo lunar seismic network to estimate the average seismic velocities in three sections of the lunar mantle: two for theExpand

Farside deep moonquakes and deep interior of the Moon
[1] An effort to find farside deep moonquakes among the recently discovered nests of deep moonquakes has identified about 30 nests that are likely to be on the farside. Although only a few of themExpand

Seismology on Mars
A three-axis short-period seismometer has been operating on the surface of Mars in the Utopia Planitia region since September 4, 1976. During the first 5 months of operation, approximately 640 hoursExpand

Crustal-scale seismic profiles across Taiwan and the western Philippine Sea
Abstract We have used combined onshore and offshore wide-angle seismic data sets to model the velocity structure of the Taiwan arc–continent collision along three cross-island transects. AlthoughExpand

Apollo Lunar Seismic Experiment - Final Summary
Processing and initial analysis of the entire set of Apollo lunar seismic data collected continuously from 1969 through 1977 have now been completed. Recent results include: 1) better defined deepExpand

Deep crustal structure of the Chicxulub impact crater
We present the results of a wide-angle seismic survey conducted over the Chicxulub impact crater. Profile Chicx-A/A1 is a chord across the offshore portion of the crater, and Chicx-B/F is anExpand

Lunar subsurface investigated from correlation of seismic noise
By correlating seismic noise recorded by four sensors placed on the Moon during the Apollo 17 mission, we have retrieved a well-defined dispersed Rayleigh wave pulse. Inversion of its group velocityExpand

Deep lunar interior inferred from recent seismic data
Analysis of recent lunar seismic data from distant meteoroid impacts, high-frequency teleseismic events and deep moonquakes shows several significant deviations of P- and S-wave travel times fromExpand

Lunar Seismicity, Structure, and Tectonics
Natural seismic events have been detected by the long-period seismometers at Apollo stations 16, 14, 15, and 12 at annual rates of 3300, 1700, 800, and 700, respectively, with peak activity at 13- toExpand
