4.6 magnitude tremor creates panic in Bulgarian capital

July 14, 2012 BULGARIAThe relatively strong tremor that threw into panic people in Bulgaria’s capital Sofia and nearby Pernik is an aftershock of the 5.8-magnitude quake at the end of May, according to experts. “What we experienced on Saturday is an aftershock of the earthquake of May 22 this year and has the same epicenter,” Professor Nikolay Miloshev, director of the National Institute of Geography, Geophysics and Geodesy, Sofia, explained. In his words it is not unusual that today’s earthquake is related to the May tremor because it was very strong and even then seismologists predicted aftershocks may continue for months. Saturday’s earthquake was estimated as 4.5 on the Richter scale by the European Mediterranean Seismological Centre and as 4.2 on the Richter scale by the Geophysical Institute at the Bulgarian Academy of Sciences (BAS). The jolt struck at 3.52 p.m. and was felt in Pernik, Sofia, Samokov, Montana and Plovdiv. The quake occurred at a depth of 10 km and was epicentered 7 km southeast of Pernik and 19 kilometers west of Sofia, very near to the epicenter of the 5.8-magnitude jolt which hit the region in the small hours of May 22. –Novinite

    Aftershock??? Really?? I’m not the expert, but isn’t that odd to call it aftershock after nearly two months after the initial earthquake? I have heard of aftershocks immediately then swarms, but a significant earthquake two months after the initial is considered as aftershock, I haven’t heard of this before.


  2. Little known items category: In the past year or so there have been about five quakes at the same spot on the border of NM and Colorado, always near the town of Trinidad. This is on the Rio Grande rift, if I read the map correctly. The first one was almost identical in time (a day apart) from the 5.8 in Virginia which got a lot of attention a year or so ago. These quakes happen months apart but keep occurring. I have not heard of much damage, but this is a fairly large quake, isn’t it?


    • I didn’t give the magnitude of the Trinidad quakes: all 5.8

        I watch the Colorado quakes because Colorado is home – I was born and raised there and return often because all of my family lives there. Earthquakes are common in the Trinidad, Colorado south to Raton, New Mexico area. Check out the geology of the area – volcanic in the past with many dykes, cones, lava flows. The Spanish Peaks are just west of this area. The Rio Grande Rift Valley actually extends north into the San Louis Valley of Colorado and possibly up over Poncha Pass north to Leadville, several dozens of miles west of Trinidad and Raton. There are several hot springs in the area and evidence of massive earthquakes in the past (it is a beautiful area with geologic evidence right along the highways for those with eyes to see).
        I’d like to know where you have seen these 5.8 quakes in Colorado listed. They have not been listed on the USGS page and family members who live near there have not felt them. Here is a list of the recent ones for Colorado (exact locations not listed):
        March 4 – 2.8
        March 6 – 3.3
        March 6 – 2.7
        March 16 – 2.9
        March 29 – 2.8
        May 24 – 3.2
        May 24 – 3.4
        June 13 – 2.7
        June 14 – 2.6
        July 4 – 2.5

        For a much longer list, check out this page: http://www.homefacts.com/earthquakes/Colorado/Las-Animas-County/Trinidad.html It goes back to 1973 and there are well over 100 quakes listed from 1973 – Dec. 2011 and the highest magnitude is 5.3 (August 23, 2011). I know there were quakes happening there before 1973 as well – that’s just when this list begins.

        I’d really like to know where you got the information on the 5.8’s happening here in Colorado because I would like to write to them and correct their information!! False information only muddies the water and then people do not believe the Truth of what is really happening!

    Alvin, what’s your opinion about the relative (literally) slow down in earthquakes over 5.0 lately? Is this a quiet before the storm?


    • We have swarms in Kuril and the Virgin Islands, and moderate earthquakes erupting around the planet. There has also been a lot of activity around Sandwich Isles near Antarctica over the last two weeks. Seismic dynamism is definitely building…


  5. Gordon says:

    Christchurch is still experiencing aftershocks 18 months after their big earthquake; in fact the whole thing is referred to a a seismic event; ie, ongoing.


  6. Joseph t. Repas says:

    I guess it’s kind of like the weather actually [ much more my knowledge ] where the lead edge of the advancing air mass creates the most violent thunderstorm but then there is usually still some remnants of heat left behind that will form more storms or just showers of lesser intensity until most of the clashing energy is dissipated.
