110 Aftershocks Registered; Moderate and Weak Tremors Possible Including Nubarashen Epicenter

Since the last earthquake that occurred on February 13 at 15:29, a total of 110 aftershocks have been recorded in Armenia. All of these tremors have been very weak, but residents in Nubarashen village or the Erebuni administrative district may have felt them. Hrachya Petrosyan, chief advisor to the director of the Disaster Risk Reduction and Seismic Protection Territorial Service, informed Factinfo about this.

The expert assured that all aftershocks were much weaker and only sensitive instruments recorded them. Petrosyan noted that the 110 aftershocks had a magnitude ranging from 0.5 to a maximum of 2 or 3. They occur at different intervals—there may be three aftershocks in one minute, while one could be recorded in an hour.

“Objectively, these are very weak tremors, but their frequency is decreasing, and their strength is also weakening, which means that energy has been dissipated in the form of the main shock, which is the strongest in this sequence,” he stated.

He added that data is frequently updated, and based on these, no new, powerful earthquake is expected. “The data indicates that moderate or weak tremors are possible, as the seismic regime has activated not only in Armenia but also in adjacent regions—Georgia, Turkish and Iranian border areas. Moderate and weak tremors are possible, including at the Nubarashen epicenter, but we have no basis to say that a strong earthquake is being prepared.”

It is noteworthy that on February 13, at 15:29 local time, a magnitude 4.7 earthquake was recorded by the seismic network of the Armenian Ministry of Emergency Situations, 8 km southeast of Yerevan, at a depth of 10 km. The intensity of the underground shock in the epicentral area was rated at 6-7 degrees. The earthquake was felt in Yerevan with an intensity of 5-6 degrees, and in the regions of Aragatsotn, Ararat, Shirak, Armavir, and Vayots Dzor with an intensity of 3-4 degrees.
