Strong earthquake shakes Lake Baykal region in eastern Russia

Location of this evening's quake in Russia
Location of this evening's quake in Russia
A moderately strong earthquake occurred in Russia this evening near the SW end of Lake Baykal. It is being estimated as a magnitude 5.3-5.5, depending on which calculations are being applied by different agencies.
The epicenter was 80 km of the regional capital of Irkutsk (pop 587,000) and the depth of the quake was likely between 10-40 km.
The quake was widely felt in the area as moderate to light shaking, but due to the very low population density, there are not many reports (yet). Strong shaking could have been expected in the area very close, within a few tens of km, to the epicenter. No major towns are located very close by the epicenter and no significant damage should be expected to have occurred. In Irkutsk, moderate shaking intensities were reported. Most people felt rattling movements that lasted a few seconds.

While most of Russia has very few earthquakes, as most of its landmass is located in the stable interior of the Eurasian plate, the Lake Baykal area is an exception: it is affected by a tectonic rifting (spreading) process, where two segments of the crust are being separated by two parallel fault systems. This so-called Baykal Rift is one of Russia's tectonically most active features and has over time created the world's deepest sweet water lake.
