Today I uploaded a calibrated cluster based on the 5.1 mw Ojai, California earthquake on August 20, 2023.

I uploaded a calibrated cluster for the Bogotá, Colombia region today. It includes the Mw 6.3 earthquake on August 17, 2023 and two aftershocks (magnitudes 5.7 and 5.0). It will show up in the ScienceBase dataset with a couple days and the mloc data is posted here.

Four new calibrated clusters were added to the GCCEL dataset today, two in Bulgaria (Sofia and Varna) and two in Romania (Bucharest and Orsova).

Today I added calibrated clusters “austin” (Nevada), “khutia” (western Georgia) and “ardahan” (northeastern Turkey) to GCCEL. It may take a few days for them to show up on the ScienceBase website and they will only appear at the ISC Dataset Repository when I have added enough new clusters to justify a new distribution. The mloc folders for these three clusters are available now on this website.

A recent version of the Global Catalog of Calibrated Earthquake Locations (GCCEL) has been published in the Data Repository of the International Seismological Centre, with the link https://doi.org/10.31905/MFDY4QHD.

I’ve posted v10.6.1 of mloc on the mloc distribution page. The Desktop User’s Manual has been updated accordingly and is available for download from the User’s Manual page.

I created a file gccel.kmz for displaying the current GCCEL dataset in Google Earth or any other program that can handle a kmz file. The file can also be downloaded from the GCCEL section of this website. Cluster hypocentroids are organized by country and shown in red; clicking the icon displays a lot of information about the cluster. Individual epicenters are shown in yellow; clicking the icon gives information on the hypocenter, magnitude and calibration level. Display of epicenters (all or none) can be toggled on or off.
