A 3.9 earthquake rumbled through east San Diego County this morning at 4:06 a.m. It was centered less than six miles from our house and, as you can imagine, shook us awake and sent us springing for the internet to see just how close it was. This was an interesting quake for us, being Southern Californians through and through, because we actually heard it before we felt it. It almost seemed like a 50-foot boulder was rolling down Vista Grande Road and past our house. It was loud and the shaking was stiff and rumbling; unlike how quakes felt when I lived in Huntington Beach where it the earth sloshes around as if floating on the water (HB sits atop a large water table). Where we live in El Cajon (actually, unincorporated county land), it's all decomposed granite, and the earthquake really hammered home that soil composition reality. A couple minutes later there was a smaller aftershock that we hardly felt, but definitely could hear. This is the first time I've ever heard a quake but not felt it.
There appears to be no damage or injuries to report on this temblor.
