What does this mean? 138 earthquakes in the past 3 days, And ours was the strongest, here in the Philippines we have experienced a magnitude?6.6 intesity 5 quake, and when i searched it up on google i was shocked, i thought we we're the only one who experienced it, but multiple countries that are not from the same continent felt it aswell, in the same time. Again, what could this mean?
