Interesting magnitude 5.2 #seismic event - presumed #earthquake in the New Siberian Islands off the #Arctic coast of #Russia 30 minutes ago (2023-07-13Z13:06) - large Lg/surface waves at station IU.TIXI (Tiksi, Russia) so presumed shallow - but very energetic Sn phase. Low P/S ratio usually means likely earthquake. Raises an eyebrow just because it is a relatively aseismic region. (My eyebrows are easily raised - don't worry.)
