Moho 2017

Moho surface using data to end 2017, together with data points used in construction.

The Moho results are organised as simple ascii files with the following format:
identifier | latitude | longitude | Moho depth | weight

The full suite of files (one per geophysical technique) is provided in a .zip file: - Gravity inversion at 0.5 deg spacing - Refraction results on land - Marine reflection/refraction results - Reflection profiling results - Results from tomographic experiments - Receiver functions - broadband inversions - Receiver functions - HK results - Receiver functions - higher frequency data - Autocorrelations - continuous data - Autocorrelations - inversion of teleseismic data

Access results

Coming soon: Moho surface models provided at 0.25 deg resolution, format:
latitude | longitude | Moho depth

(a) Spline interpolation
(b) Gaussian weighting

Access Models
The Moho depth is estimated from a combination of geophysical techniques, including but not limited to the analysis of passive seismic data archived at AusPass. The techniques and data sources used to build the AusMoho collection are listed below with relevant references. The collection is the most complete at this date (31 May 2019), and includes estimates that have not yet been integrated in the AUSREM model, released in 2012 (see Salmon et al., 2013 in compilations below). Please, also check recent updates on the AusREM website.
