On the evening of 10 November, at 21:57 local time, a very small earthquake occurred under the southern slope of Mount Aragats, near the village of Byurakan. With a magnitude of ML 0.9 nobody could feel it, yet three CHARNET stations recorded it, and the epicentre was located at 40.39° N, 44.28° E, at a depth of about 16 km.

Our Byurakan station stands almost above the source, less than 5 km away. There the S-wave arrived only 2 seconds after the P-wave. At Gyulagarak, 63 km away, the gap was 8 seconds, and at Deghdzavan, 110 km away, 13 seconds.

Aragats, the highest mountain of Armenia, is an extinct volcano. Our Byurakan station, next to the famous astrophysical observatory, listens to its southern slope day and night, and even the smallest tremors under the mountain do not pass unnoticed.
