B. Fire from the sky
We`re all used to hearing about tornados, but imagine if a tornado was a whirling fire storm instead of a wind storm. A fire tornado or a "fire devil" can happen when high temperatures from a wildfire mix with strong winds. They are usually about 300-450 metres high, but they can sometimes reach 1.6km in height! A fire tornado made world news in 2010 in Brazil when astonished motorists watched one spin and burn its way through fields by a highway. In 1923, the Great Kanto Earthquake in Japan ignited the largest fire tornado in history, killing 38.000 people in 15 minutes. Luckily, fire tornadoes are very rare.
C. A watery tale
Have you ever heard the saying "it`s raining cats and dogs"? Well, what about frogs, fish, jellyfish or even snakes? Believe it or not, there have been many stories throughout history of it raining animals. One explanation is that strong winds or a tornado could pick them up and drop them far away. The rain of fish has been happening every summer in the region of Yoro, Honduras, for over a century. Witnesses say that there is usually a violent storm, then afterwards there are hundreds of living fish on the groundd which people take home, cook and eat! Many local people believe that this is a miracle, but some scientists disagree: they believe that the fish are from underground rivers and that the storms somehow bring them up above ground.
