A unique geographical phenomenon usually formed by volcanic activity in plateau regions. Due to the high altitude characteristics of the plateau, it often has more spectacular geomorphological features. The crater is the eruption outlet at the top of the volcanic cone, and its shape is mostly nearly circular, which may be funnel-shaped or flat at the bottom. In the plateau area, the formation of the crater may be accompanied by the eruption of a large amount of volcanic ash and magma, which formed the landform around the crater after cooling. It is not only of geological significance, but also provides a unique environment for the ecosystem. The surrounding soil is often able to support the growth of abundant vegetation due to the fertility of volcanic ash.

Also known as sandstone landform, it is a type of landform formed by sandstone development. Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles or rock fragments. Common minerals include quartz, feldspar, and clay minerals. The difference of mineral composition, hardness and cementation degree will lead to different geomorphological forms. Quartz sandstone or siliceous cemented sandstone often forms relatively high mountains due to its strong weathering and erosion resistance, while coarse sandstone and feldspar sandstone that are not firmly cemented often form hills or basins. After a long period of erosion and weathering, the formation of a variety of strange landforms.

It is a volcanic island in the Lipari Islands in northern Sicily, Italy, just 12 miles off the coast of Sicily, and is the closest island to Sicily in the archipelago. The island's volcano is one of only two active volcanoes in the area, the other being Stromboli Island. It is known for volcanic phenomena, including high-temperature steam emissions, which come from craters or cracks in the ground. The name comes from Vulcan, the god of fire in ancient Greek and Roman mythology. The island has a long history of volcanic activity. The last eruption was recorded between 1888 and 1890.

Also known as Lawetlat'la or Louwala-Clough, is a layered volcano located in the U.S. state of Washington, part of the Cascade Mountains. It is famous for its catastrophic eruption on May 18, 1980, which was one of the deadliest and most destructive volcanic events in U.S. history. During this eruption, a massive landslide occurred on the north side of the volcano, creating the largest debris flow in history. After the eruption, the height of Mount St. Helens was reduced by about 400 meters, forming a huge crater.
