The paper presents the results of the analysis of macroseismic and instrumental data of the earthquake that occurred on April 3, 2023 at 03:06 UTC in the southern part of the Avacha Gulf (Kamchatka) at a depth of ~105 km. This earthquake was named “Vilyuchinsk earthquake” – its epicenter was located 47 km from Vilyuchinsk town. It was felt in the range of epicentral distances Δ up to 555 km. Maximum shaking with intensity I = 5–6 was recorded at four locations (Δ = 40−62 km), including Petropavlovsk-Kamchatsky and Vilyuchinsk. Peak ground motion accelerations exceeded 20 cm/s on records from 23 digital accelerograms (Δ
