Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In 2016–2017, the seismic monitoring in Kazakhstan was conducted by two Organizations: Seismological Experience-Methodical Expedition of the Committee of Science of the Ministry of Education and Science of the Republic of Kazakhstan and the Republican State Enterprise «Institute of Geophysical Research of the Ministry of Energy of the Republic of Kazakhstan». The paper presents detailed information on seismic observation networks. The joint catalogue based on the data of two organizations was compiled. It includes 1240 earthquakes having energy classes KR=6.6–15. The strongest earthquake within the considered territory occurred on August 8, 2017 with mpv=7.0, Mw=6.3, KR=15. Its epicenter was located on the territory of Xinjiang (China), near the Kazakhstan-Chinese border. The earthquake was felt in numerous settlements in Kazakhstan. Another strong earthquake occurred on April 4, 2017 with mpv=5.8, KR=13.3, Mw=5.3 in the Eastern Kazakhstan, near Zaysan Lake. Its maximum intensity 5–6 was recorded in Zaysan town. In whole, the period 2016–2017 was characterized by moderate seismicity for the major part of the country’s territory.
