Hello once again with another story.

It has been a century since a massive disaster has happen. But, there's one threat that's even worse than Discord's chaotic change and the Changeling's invasion. And the worst part? It can't be stopped.

It was a warm May morning in Equestria, and me and my platoon were looking for something in the Unicorn Range. Apparently, we were woken up to the ground shaken below our hoofs. Celestia immediately called for all of us, and sent us out in squadrons to look for the source. While the others were still looking, what we found was something we never expected to see.

Shining didn't know what to think of this discovery. Sure, he knows what it is, due to Celestia mentioning it and explaining it at times, so he's not clueless. However, he didn't say anything to his squadrons. He just told them to keep a look out for anything that doesn't seem normal or out of place. But he didn't expect this.

We sat there, while Shining told his squadron the discovery. I was quickly writing notes about the shocking discovery.

May 15.

Unicorn Range, Equestria

2:32PM.

Ever since Celestia sent us over here out at Unicorn Range, we were shocked to find a discovery, all be it not a good one. We found the ground divided by a long and wide ravine.

We're not sure what to call this discovery. Shining Armor said it 's a fault. Whatever that means, and it was caused by this earthquake. He told us to NOT alert the citizens throughout Equestria, in fear they will go crazy at the discovery.

So far, this fault has destroyed a vital railroad connecting Manehatten, Fillydelphia, Vanhoover and other establishments up north. Until then, all travelers and business ponies have been informed that railways north of Canterlot has been cancelled due to maintenance issues.

I hope it's nothing too serious to worry about.

I finished and looked at Shining Armor. "Captain, do you think it's going to get worse?"

He simply stared at the massive opening in the ground, and didn't know what to say. "I hope it doesn't. The fault is close to Manehatten and Fillydelphia that we can't risk any lives to be gone. However, I'm fearing the worst." Shining said, before ordering all of us to return to base at Canterlot.

At Ponyville

At the Golden Oaks Library, Twilight was looking franticly around the library, while Spike was looking from top to bottom for the book she was looking for.

"I know it's here somewhere. Did you do something with it Spike?" Twilight asked.

"I know I did put it somewhere on the shelves." Spike said, until he found the book. "Twilight, I found it!"

Twilight used her magic to quickly take it from my grasp, and was now looking through the pages. After a while, she stopped on the page she was looking for. "Aha! I found what Celestia was talking about." She said, excitedly.

"Well, what does it say?" Spike asked.

"What Celestia was talking about is called a fault, and it was caused by an earthquake."

"Wait, what's an earthquake and a fault?" Spike asked, confused about words he never heard of.

Twilight then read straight from the book. "Well, it says here 'In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement as a result of rock mass movement. Large faults within the Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes.

An earthquake (also known as a quake, tremor or temblor) is the perceptible shaking of the surface of the Earth, which can be violent enough to destroy major buildings and kill thousands of ponies. The severity of the shaking can range from barely felt to violent enough to toss ponies around. Earthquakes have destroyed whole cities. They result from the sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.' So Equestria is on an active tectonic plate" Twilight's smile faded into a look of horror and realization of what she just said.

"Uh, Twilight?" Spike was waving his hand in front of her face.

"Oh no. This is bad."

"How is it bad Twi-"

"Because Spike, didn't you hear what I just said!?" Twilight screamed in panic, as she shook Spike. "Equestria is on an active tectonic plate! Do you KNOW what that means!?"

"Uh, no." Spike said, scared.

"It means the ground can shake violently at any point! I can't let this be uninfo-"

She didn't finished what she was saying as both of them felt the ground shake. Sure, it was a minor. But add Twilight, who is now terrified of what Equestria lies on, and she was indeed terrified. As the quake was going, Spike saw a few books fall from the shelves, the cart moving back and forth, and he saw Twilight trying to comprehend what is happening. The quake went for a solid 8 seconds. Afterwards, it stopped.

Twilight was trying to come up with solutions to this natural disaster. Obviously, you could use magic. But, understand the word 'natural', and you know why that won't work. Before she can do anything, her friends barged in.

"Twilight, did you felt that?" Rainbow asked, almost scared. Twilight didn't say anything and only stood there. Fluttershy was being cared by Rarity and Applejack.

"It's a'ight sugarcube. Nothing was harmed to ya animals." Applejack tried to comfort Fluttershy, but it was proven worthless as she was still shaking.

"I-I-I don't l-like seeing t-the animal-ls s-scared like t-t-that." She said quietly.

"Oh, hush now dear. Your animals are safe, and so are you. I'm just wondering what caused that shaking." Rarity said also a bit shaken. She was comforting Fluttershy, until she noticed Rainbow near Twilight, trying to get her attention. But was proven futile.

"Hello? Equestria to Twilight! Are you there?" Rainbow yelled, to which Twilight was now listening.

"Oh. Sorry Rainbow." She said, putting on a smile, but still horrified by the thought of what happened a few moments ago.

"Twilight, do ya know what happened?" Applejack asked.

"Yes. I exactly know what happened." After that, Twilight went to explaining to her friends what had just happened. She even showed a few pictures of the outcomes. The first picture was of Manehatten back in the olden days, almost completely unrecognizable. The famed Bridleway Theatre District was in ruins, as nothing but the uneven ground and a few buildings toppled over is what remains. The second picture showed the Mane Fair Hotel completely shown as nothing but piles of rubble, and injured ponies being shown along with EMT's and carriages hauling injured ponies away. The third picture was a newspaper clipping at the time titled:

BREAKING NEWS! WORST NATURAL DISASTER EVER TO DATE IN EQUESTRIA!

The girls were all shocked by the information Twilight just showed them. Fluttershy was scared beyond anything, while Rainbow and Rarity were trying to comfort her, while just as terrified. Applejack was now very worried about her aunt and uncle, and Pinkie Pie was… wait. She's not even here.

"Uhm girls, where's Pinkie?" Twilight said, completely fearing the worst.

"I'M RIGHT HERE!" Pinkie shouted popping out of nowhere, and once again terrifying Fluttershy.

"Pinkie, what did we say about doing that!?" Rainbow yelled, furious at Pinkie.

"Oh, hehe. Sorry." Pinkie said innocently, while Twilight rolled her eyes as she continued.

"If we don't inform this to Celestia and Luna, who knows what else will happen. Spike, prepare a letter." Spike soon returned with a quill and a scroll.

"I'm ready when you are Twilight."

Twilight cleared her throat and said "Dear Princess Celestia, I just discover some terrible news that must not be kept a secret. I found a book called 'Natural Disasters', and I'm not sure if you felt it, but there was an earthquake that happened. This cannot go without informing all citizens of what has happened. Please, get back to me as soon as possible. Your faithful student, Twilight Sparkle." Spike then rolled it up and incinerated the scroll into green dust.

Moments later, Spike burped out a scroll and read it. "Twilight Sparkle, what you just discovered is definitely something of importance. I'll be there momentarily, Princess Celestia."

A bright light engulfed the room for a moment. Once it cleared, Princess Celestia and Princess Luna were standing there. Before anyone could bow, she said quickly.

"There's no time for being formal." She then turned her attention to Twilight. "Is this true of what you speak of Twilight?"

"Unfortunately, yes Celestia." Twilight said.

Celestia didn't say anything for a minute. Everypony was waiting in anticipation of what Celestia would say, with Twilight being the most out of all in the room. After a minute of silence, Celestia said.

"I feared this would happen. I thought I got rid of it centuries ago."

"Wait, what are you saying?" Twilight asked.

"Back when me and my sister were young, our parents tried to resolve the issue of another earthquake. So they used magic to seal up the fault that existed. Over periods of time after our parents passed away, the fault was building a lot of stress and was under a lot of pressure. After the magic seal broke, Equestria was hit by a massive earthquake. Followed by tsunamis along the coast. It was definitely the worst we've ever experienced. I can't tell you how high the death toll was" Celestia explained briefly. "It was really the worst disaster that ever happened."

"Well, why don't you seal it again? You obviously had the powers to seal it up, right?" Rainbow asked, completely oblivious to what Celestia just explained.

"I don't want Equestria to be in another massive earthquake. Anyways, a few years after the quake, the Royal Guard has spotted a massive fault on the base of the Unicorn Range. Me and my sister didn't want to seal it up, as Equestria was only recovering at the time. So, we left it to be. But I feared it's getting worse." Celestia finished.

She then hold up a piece of paper, to everypony's confusion and explained. "This paper is the report the Royal Guard founded. According to this, it's only expanding and is showing no signs of stopping. This fault is near the two largest cities in Equestria, and it's only getting closer."

"So, there's nothing we can do to stop it is what you're saying?" Twilight said, with hopelessness in her voice.

"Unfortunately, that is correct." Celestia said sadly.

Everypony in the room didn't know what to think of this. Twilight didn't think of any solutions and didn't know what to think, Applejack was very worried about her family, Rainbow and Rarity had looks of hopelessness and so did Fluttershy. Pinkie was sad, and had a look of fear. Celestia didn't know what to do except look at all of their expressions.

They were all terrified of the mere thought of it happening at any point. They only came with one possibility: Equestria is doomed.
