Indiana earthquake: a 'very loud boom'

[Update 12:14 p.m.:] The U.S. Geological Survey has downgraded the earthquake from a 4.2 magnitude to a 3.8 magnitude.

[Original post] Debra Sholty was just opening up her business Thursday morning in Kokomo, Indiana, when a magnitude 4.2 earthquake rumbled through the north-central part of the state.

"It was like a huge explosion under your feet," said Sholty, the owner of Hobson Cleaners.

According to the U.S. Geological Survey, the quake struck just before 8 a.m. ET and was three miles deep. Its epicenter was located about 15 miles east-southeast of Kokomo, and 50 miles north of Indianapolis.

    I appreciate everyone feels they have something else they want to talk about. But has anyone thought to ask about the BOOM this created? I have never heard an explosive boom like this in an earthquake. I was sitting at work in Indianapolis when I heard what sounded like an explosion. This explosive rumble impacted the building, the windows. I felt more from that boom than I felt quake beneath my feet. Are there any other Indiana residents who thought this was an explosion? I was amazed to find out a few minutes later online that it was an earthquake.

    I would like to hear from someone who knows about seismology and earthquakes. Do earthquakes cause this kind of explosive boom? It's very deceptive. People I know who live in Kokomo near the epicenter of this quake called and reported an explosion to the police...not an earthquake. I would just like to know if it is common to hear such a loud boom. Thanks to anyone who can lend an intelligent answer.

      Down here in Evansville, there was an earthquake a few years ago that woke me up. It was louder than strong. I could tell it was an earthquake, though.

    I don't know why anyone would want to leave this earth. Seems to me a truly loving God who spent so much time and energy making us this home would kick that bad people out and leave the good people to enjoy this earth the way he originally purposed. There's nothing wrong with the earth once those ruining it are gone.

    I've experienced several earthquakes. None of them came with a "boom" though. This is very odd.

    Lana –
    More than 500 measurable earthquakes have been reported in central Arkansas since Sept. 20, 2010 to Dec. 24. Normal for a year in Arkansas is under 100 quakes. Experts are looking at salt water disposal wells where drilling waste (fracking water loaded with chemicals) is injected back into the earth after drilling. Hope there's not a lot of fracking happening there but if there is it might be worth thinking about.

    Yes! Earthquakes can and do create a loud explosive sound that sounds very similar to artillery fire. The doppler effect can also be pretty impressive. I was tired and struggling through a lamaze class with my wife. I was sitting on the floor with my head against a window sill. A 4.9 boomer cracked loose directly below the area. The women, all 17 rolled out of their bean bag chairs.the only injury was me. It fely like I was hit with a sledgehammer. The sonic boom was very much like standind behind a tank in the army.I was also in the loma priarda and that one was more of a rumbling sound. But visually was absolutely astonishing!

  11. phil you heard an explosion while you at the lamaze class? Like, if you were calling a friend and telling them what happened, you would tell them there was an explosion rather than telling them it was an earthquake?

    @2100...we know earthquake activity is increasing. We are just wondering if our extracting hydrocarbons from the earth might have something to do with it.

    According to the USGS (US Geological Survey) the US rarely experiences major earthquakes, and the frequency of our most common earthquakes has increased over 50% in the last 10 years.] This is not because we have developed more accurate ways of detecting eq's, it's because we are experiencing more eq's.

    Ahh-MS. miller / I lived in SO.CAL. When i was younger n been through many qaukes, earth quakes dont start off with a explosion!!! They start off with a low-tone gradual RUMBLE that intensifies with the magnitude of the qauke , as you sit there trough the shake,rattle, n roll. Its also a well known fact our GOV. Detonated many underground NUKES in pre-cold war testing and guess what the earth shook, what happened today is withen our GOVERMENTS ability.
