Introduction: Studies of the compensation state and evolution of lunar impact basins using gravity and topography data have revealed much about the early thermal history of the Moon [e.g. 1, 2, 3]. While Mars has had a far more complex history, it is likely that the ancient martian impact basins also have much to tell us about the early thermal evolution of the planet. To address this, here we ...

Plate tectonics is largely responsible for material and heat circulation in Earth, but for unknown reasons it does not exist on Venus. The strength of planetary materials is a key control on plate tectonics because physical properties, such as temperature, pressure, stress, and chemical composition, result in strong rheological layering and convection in planetary interiors. Our deformation exp...

The deep crustal and upper mantle structure of the Yilgarn Craton is investigated in this study using receiver-function analysis of teleseismic earthquake records from temporary stations. Two lines of stations were deployed, the main transect ran between Perth and Kalgoorlie, and a second line of stations ran across the east Yilgarn Craton 200 km to the north of Kalgoorlie. The broadband instru...

The 900 instrument Mount St. Helens nodal array recorded continuous data for approximately two weeks in the summer of 2014 and was deployed contemporaneously with the active source component of the iMUSH experiment (imaging Magma Under St. Helens). Two distinct imaging methodologies are applied to node data 1) reverse time imaging (RTI) is used to automatically detect and locate microseismicity...

Online learning algorithms are typically fast, memory efficient, and simple to implement. However, many common learning problems fit more naturally in the batch learning setting. The power of online learning algorithms can be exploited in batch settings by using online-to-batch conversions, techniques which build a new batch algorithm from an existing online algorithm. We first give a unified o...

Teleseismic receiver functions (RFs) from a yearlong broadband seismological experiment in Kamchatka reveal regional variations in the Moho, anisotropy in the supra-slab mantle wedge, and, along the eastern coast, Ps converted phases from the steeply dipping slab. We analyze both radialand transverse-component RFs in bin-averaged epicentral and backazimuthal sweeps, in order to detect Ps moveou...
