Wrong. The lunar cry is a naturally occuring phenomenon, but happens very rarely. Tears Point has some natural attraction to a lunar cry or something, while the Lunatic Pandora was specifically built to cause a lunar cry by using a massive moonstone. Combining the two is simply a way of triggering a lunar cry without having to wait thousands of years!the lunar cry can only be called from tears point with lunatic pandora. The crater is something else all together but dont ask me what.
So as Skyblade said, the Trabia Crater is the previous location of a lunar cry. The lunar cry that wiped out Centra was another lunar cry. Several have occured throughout history. From the Tutorial:
Lunar Cry
Refers to monsters falling from the moon. Completely destroyed the cities of
Centra. Occurs when monsters reach a saturation point on the moon. It's
believed that there are factors on the planet that cause this phenomenon.
This phenomenon has occurred many times in history and will reoccur in the
future.
Lunatic Pandora
An enclosure for Crystal Pillar made by Esthar. 3 miles tall and 1.5 miles
wide, the enormous enclosure boasts a high-tech facility. It floats by causing
a reaction with the Crystal Pillar. A stone from the moon is sealed inside. It
was probably built to cause the Lunar Cry through artificial means.
Crystal Pillar
A crystal that causes the Lunar Cry by producing a strong energy field between
the planet and the moon. It's believed to have originated in the moon. The
Crystal Pillar responds to a specific location on the planet, and sends a
strong directional signal. More research is required to analyse this process
in detail.
Tears' Point
Lunar Cry's point of origin determined by Esthar scientists. A security box
restraining the power of the Crystal Pillar and ground energy field is set up.
It is sealed to prevent the Crystal Pillar from entering the area.
