It is calming down with the volcano for now. “It will explode for sure, but we don’t know when.” Earthquakes are still going on and I would like to mention them, or rather to record them. Because when we hear about earthquakes, we see scenes from the movies: the house is teleported, the earth is parting, bricks fall on the head. In fact, the quake lasts a maximum of a few seconds, usually less. Sometimes objects tremble, sometimes it feels like the chair you are sitting on has started to float. Sometimes you hear a quake, a bit like a train passing outside the window. But often you can’t hear anything, you can only feel it. And it’s not always vibrations – rather rocking.
Today I set up the recorder in an empty room, recorded for several hours in long. During lunch, I felt my chair rocking, and after waiting a while (in case there were any aftershocks) I ran to the studio to see if anything was recorded. I opened the sound in the editor and saw clearly a few lumps in the wave and a line. This dash was some object that had probably tipped over. The lumps, on the other hand, I couldn’t hear. I raised the low frequencies a bit and then I could actually hear something. Or, in fact, feel it, because the sound is so low that it’s more like vibrations reaching the head. When it comes to the speakers – you can hear it, as long as the speakers have reasonably good bass. Nothing is happening on the iPhone speaker.
I think about it all the time, but I seem to have captured this unique earthquake phenomenon in this recording, which you cannot hear but feel. That is why I recommend listening with headphones, preferably earphones. Make yourself an Icelandic earthquake in your head 🙂
Anyway, that’s not my last word. The recorder will still work, maybe someday it will be possible to record something more obvious.
