The shock of the recent earthquake in Pakistan has brought another shock: the rise of a small, mysterious island, coming out from the water.

In the aftershock of the earthquake, people living in Gawadar, near the southwest coast, began to see a strange sight. They looked out into the Arabian Sea and saw a mountain-like shape coming out of the water. “I could see this gray, dome-shaped (穹顶形状的) body in the distance, like a giant whale,” Bahram Baloch, a local journalist, told the BBC. “Hundreds of people had gathered to watch it in disbelief (怀疑).”

So what happened? The earthquake measured 7.7 in magnitude (地震级数). The force was so strong that it moved the sea floor, releasing gas. This gas pushed the seabed, mostly rock and sand, upward and out of the water. This is how mud volcanoes (泥火山) are formed. The island that measures about 20 meters high, 30 meters long and 90 meters wide is actually the tip of the mud volcano.

Is it safe? Although people have visited this new island, scientists have found dangerous gas coming from the newly formed island. “Our team found bubbles rising from the surface of the island, which caught fire when a match was lit,” said Mohammad Danish, a scientist, to Universe Today.

These mud volcanoes are not rare. But it’s striking because this one has popped up in a populated (有人居住的) area, and not far out in the sea. However, it’s not expected to last very long. Most of these mud volcanoes are swept back under the sea within one year.

The human brain weighs about 1.4 kilograms, but it can, hold much more information than most computers. However, there is another difference between humans and computers. Computers don't forget information they are given, but humans often do. No one remembers everything, and luckily we don't usually have to. But everyone can improve their memory if they want to. Here are some suggestions.

◆Try to use new informati6n immediately. For example, if you meet someone who says "Hi! I'm Carlos," don't just say "Hello." Repeat the person's name. Say"____"

◆Break a big number into smaller parts. For example, it's hard to memorize (记忆) 109244153. But if you break it into three parts--109/244/153—it becomes easier.

◆Write out what you need to remember ever and over again. This will help you keep it in mind longer, especially for memorizing formulas (公式) or facts.

◆Always review information. If you bring what you've learned back to your mind, they become easier to remember. For example, before you go to sleep, it’s a good idea to review the new things you learned that clay.

◆Discuss with a friend. It is always easier to remember things through discussions. You can have a discussion about what's right and what's wrong, and it will lead to the right answer.

Never tell yourself that you have a bad memory. You can always do something to help improve your memory. And everyone's memory gets better if they use it often enough.

All of the suggestions are helpful. If you follow them, you are certain to improve your memory.
