Attenuation and velocity tomography of the northern East African Rift

This dataset corresponds to compressional (P) and shear-wave (S) velocity (V) and attenuation (q) teleseismic tomography of the MER, from rift to flank. This is the most comprehensive body wave travel time and attenuation dataset collected in the MER and Afar to date, where attenuation (quantified as t*) is collected using a new methodology for measurement and quality control of differential t* for teleseisms, avoiding extrinsic focusing. The resultant imaging includes the only 3-D attenuation tomography model of a continental rift. Together, the well-resolved co-located models (VP, VS, qS) help constrain the physical conditions within the rift through Bayesian analysis that makes explicit parameter trade-offs. 
The northern East African Rift, including the Main Ethiopian Rift (MER) and Afar, have been the focus of decades of seismological investigations and dense broadband coverage. Sometimes invoked as an archetype for a narrow continental rift, the confined surficial extension h..., All details are provided in the associated manuscript., , # Attenuation and velocity tomography of the northern East African Rift

## Description of the data and file structure

### Files and variables

#### File: evinfo.mat

**Description:** MATLAB file with information about the earthquake events used in the study. Not all earthquakes provided usable data. 

###### Variables

* evinfo is a structure with [`norids`x1] arrays corresponding to the number of earthquakes (`norids` = \"number of origin IDs\"). It contains the following fields: orids (Origin IDs, simply a numerical label of the earthquake), `elats` (latitudes), `elons` (longitudes), `eldeps` (depths, in km), `evmags` (moment magnitudes), `evtimes` (origin times, in serial time format), `evtimes_IRISstrs` (origin times, in 'yyyy-mm-dd HH:MM:SS:sss' format), `datestamp` (origin time in 'yyyymmddHHMM' format).
