Status Update: ANSS ComCat Earthquakes Pushed to AWS S3 Bucket

A few months ago, I noted that earthquakes for Oklahoma after 2017-03-01 were not showing up in the NCEDC download.  Vexed by this, I immediately went searching for an alternative source of earthquake information.  Finally, I found the ANSS ComCat catalog, but could only access the full download of earthquakes via a ReSTful API that limited rowsets to 20,000 rows per request.  Knowing those limitations, I authored a Python 3 program that would download earthquakes one month at a time, starting from 1900-01-01.

The preceding download has been accomplished and the dataset has been downloaded from 1900-01-01 to the present.  I can confirm that Oklahoma’s information now appears within the dataset from 1974 to the present, hence I’ve pushed the earthquake dataset to the AWS S3 quake-info bucket.  When I’ve done so, I’ll post links to the actual Python projects at GitHub that download (PyQuakeReSTer) and reverse-geocode (PyGeoCoderRev) the data prior to its import into a SQLite3 database for subsequent analysis.

Update: FracFocusCSV data blending with chemical toxicities

The new FracFocusCSV files, found within FracFocus.org’s FracFocusCSV.zip archive, lend themselves to blending with chemical toxicities using the CASNumber column of each row.   I’ve modified the PyZip2Src2Tgt project, on the “toxicities” branch, to blend the appropriate chemical toxicity based upon the CASNumber of the row in question.  The data blending with chemical toxicities has not yet been checked for validity, so if you use the program, you’ll need to verify its results.
