Siudad del Este, Alto Paraná (855.4 km E of epicenter) [Map] / Very weak shaking (MMI II) / horizontal (sideways) swinging / 2-5 s : Studying for a final dermatology exam tomorrow, i was sitting on my chair when i felt a sudden motion described as swinging sideways very weakly for about 3-4 seconds. I rose from my chair to check if a large vehicle was passing on the street and there was none. I sit back on my chair expecting a new tremor and i felt a weaker 1.5-2 seconds tremor in the same pattern as the first one. Just those 2 tremors. | 26 users found this interesting.
