Moscenica / Moderate shaking (MMI V) : Pretty strong and long shaking this page needs to seriously revalue their knowledge about magnitudes | 2 users found this interesting.
- Hi. Thanks for the feedback. We go by scientific definitions for magnitude and sometimes they do not reflect reality. We are working on refining this however. Keep safe!
- Im guessing since it was a shallow earthquake it was felt strong. That happen in Spain recently. It was a 4.4 but it looked like a 5.0 or more. Prayers to Croatia
