Article: The Ring of Fire covers 4,000 km around the edge of the Pacific Ocean.It includes the countries of Japan,Indonesia and the Philippines.More earthquakes and volcanoes occur in this area than anywhere else in the world.The name Ring of Fire refers to areas below the earth's surface.These areas move suddenly and often cause earthquakes and create volcanoes. Many areas of Asia,such as the Philippines,Japan,and Indonesia, sometime experience earthquakes and volcanoes.There are occasionally landslides ,mudslides,and tidal waves as a result.Fortunately, these natural disasters do not happen very often. Southern China is about 600 km away from the Ring of Fire.Sometimes, people in this region feel earthquakes too.The worst earthquake felt in southern China was in 1918 in Shantou.It measured 7.3 on the Richter scale.Any earthquake of 6 or more on the Richter scale is very dangerous to people. People in Hong Kong sometimes experience the effects of earthquakes and volcanoes.In September 1994,for example,the strongest earthquake to hit Hong Kong for 76 years shook buildings and scared thousands of residents.Frightened workers and families ran out of their offices and homes.The earthquake measured 6.5 on the Richter seal. It is difficult to predict when an earthquake will occur In countries within the Ring of Fire, buildings must be very strong because the effects of earthquakes on buildings are terrible. In June 1991, Mt Pinatubo in the Philippines erupted.Many people were killed and the area surrounding the volcano was badly damaged.Hot ash and liquid rock from the volcano forced people to leave the area.They only returned many months later.The ash spread over a large area.Even people in the Guangdong region of southern China saw ash in the air.

Article: I have two sons. They are as different as night and day. My youngest is sweet, loveable, easy-going, and finds joy in everything. My oldest we've nicknamed the "Evil Genius" is ambitious, self-confident, and suffers no fools. Whenever we mentioned Santa my husband and I were rewarded with major eye rolling and deep sighs from my oldest. At first we both tried to ignore it. We both knew that our eldest had figured out the big secret. But I'd be damned  if he was going to ruin it for his six-year-old brother who had plenty of Santa-loving years ahead of him. I looked at my husband in the eye and said, "I'll handle this." to which he responded "Okay just be careful because I'm not sure he knows - he might just be acting like it." But I knew. And I had it in my mind that he was about to break his younger brothers spirit and break the news to him. I was afraid he was going to take the Christmas spirit away from my sweet innocent youngest and stamp all over it. I had to protect him. I needed to control this now before it got out of control. I rushed into the play room where my oldest was playing alone. I looked him dead in the eyes and said: "Well you know Santa isn't real, right?"  And as I stared at my eight-year-old son for what seemed like a long time of silence, his eyes started to fill with tears.  And a tear dropped down his cheek when he screamed out, "He's not?" "Um well it's not that he's not real (shut up you idiot  - stop saying he's not real), but he doesn't really make and deliver all the toys. Dad and I get some of them for you. So he's real. He's just got a little help from us."  _ . He just sat there looking at me with an expression of doubt. You know when you make a terrible mistake but you can't stop yourself from making it worse? That was me because I just had to know. I had to know why he had seemed to be over Santa. So I asked him why he rolled his eyes and sighed every time his father and I mentioned Santa. To which he replied that kids at school had been saying Santa wasn't real but that he still thought he was.
