![]() Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. The plate boundaries are made up of many faults, and most of the earthquakes around the world occur on these faults. We call these puzzle pieces tectonic plates, and the edges of the plates are called the plate boundaries. The earth has four major layers: the inner core, outer core, mantle and crust. The crust and the top of the mantle make up a thin skin on the surface of our planet.īut this skin is not all in one piece – it is made up of many pieces like a puzzle covering the surface of the earth. Not only that, but these puzzle pieces keep slowly moving around, sliding past one another and bumping into each other. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock! What causes earthquakes and where do they happen?Ī simplified cartoon of the crust (brown), mantle (orange), and core (liquid in light gray, solid in dark gray) of the earth. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Mainshocks always have aftershocks that follow. The largest, main earthquake is called the mainshock. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. ![]() ![]() The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. The surface where they slip is called the fault or fault plane. We prefer for the ocean/water to play the primary role in content.A normal (dip-slip) fault is an inclined fracture where the rock mass above an inclined fault moves down (Public domain.)Īn earthquake is what happens when two blocks of the earth suddenly slip past one another. Whenever we do police content, it's usually because it's a repost or focuses on a sea creature rather than the vastness of the ocean or the unknown depths of a body of water. We're just a bunch of people sharing stories, images, and videos of bodies of water that leave us in awe, wonder, and trepidation. The reason we do so little policing can probably be explained by our subreddit's niche context that revolves around a very specific set of inoffensive content. "Compared to other subreddits of our size, we don't feel like we police posts or comments as much. "Our core mod group has 4 active members, which is a small team for a subreddit of our size," they told Bored Panda. We contacted the moderators of 'Thalassophobia' and they were kind enough to have a little chat with us. Part of it can be attributed to the clear rules that promote being nice and courteous, and allow no jokes, memes, or cartoons, no reposts, and no gore.īut of course, having an active moderator team that make sure members adhere to these rules helps tremendously as well. Online groups that get this big often suffer from huge streams of content that flood them with questionable pictures and videos, diminishing the overall experience of browsing them, but this subreddit manages to stay clean.
