5.8 is not that strong probably.

In strong earthquake people would find it terrifying even just standing up as the ground moves into every direction as if an invisible giant playing with it. Standing up would be scary and requires a struggle somewhat but especially strong nerves, running however would be IMPOSSIBLE without falling all over. In strong earthquake most people would kneel down with hands holding the ground out of fear and to get a sense of bearing/balance.

Most people would think that earthquake causes mere tremors but they couldn't be more wrong as in truth the ground would literally move all over the place.

if it was just tremor, mild shaking or swinging that would mean the earthquake is not that strong or not that near or not that shallow but if the ground literally moves all over, start praying and get out as fast and as best as you can if possible.
