A calibrated cluster based on the recent Hualien 7.4 Mw sequence on the northeastern coast of Taiwan has been uploaded to the “mloc data for GCCEL” section.

The cluster is based on the 4.8 Mw earthquake that shook New York earlier today. The rest of the cluster consists of small events, mostly less than magnitude 3 and observed only within about 700 km.

I uploaded the Antofagasta cluster, named after Antofagasta, Chile. It includes the Mw 7.7 “Tocopilla” earthquake on November 14, 2007.

I updated the Port au Prince cluster to include more recent events, particularly the August 14, 2021 7.4 Ms earthquake.

The Fin-Tiab cluster in southern Iran has been updated and three new clusters in the U.S. have been uploaded: Falls City, Texas, Smith’s Ferry, Idaho, and Dillon, Montana.

In light of the recent M5.1 earthquake, I updated the Prague, Oklahoma cluster with earthquakes (mostly small) that occurred since the end of the original Prague cluster (January 2012).

Since the last post in August 2023 nine new calibrated clusters have been added: Salton Trough, California; Wuqia, China;Kardzali, Bulgaria; Ontario, California; Kara-Say, Kyrgyzstan; Bayugan, Philippines; Toyama, Japan; Salcha, Alaska; and Pasaman, Indonesia.

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).
