Guayaquil (210.8 km W of epicenter) [Map] / Moderate shaking (MMI V) / horizontal (sideways) swinging : I live in a high rise building. I was sitting on a sofa with my feet on the floor. I felt the whole building swaying back and forth. Before I felt the swinging, you could hear the windows popping first, groaning, then the building started swaying. It was strong for about 40 seconds and then the building just kept swaying. The building did its job, but I do say, this felt way stronger than the last 4 quakes we had recently. No shaking like the last few but swaying. Very powerful feeling. | 2 users found this interesting.
