Andy : Brian, how do you think about the current forrest fires? It is everywhere in the news.


Brian : Yes, Andy, it is a big fire there in Sumatra. It cause a lot of smokes, which is harmful to health. I think it si because of forest clearing by irresponsible people.

Andy : Forest clearing? How does that cuase forest fire?

Brian : Companies and farmers often cut their land before they plant new crops. The problem is that after that they burn the trees. The fire can then spread uncontrolably to the forest.

Andy : Surely the dry season helps the spreads too.

Brian : Yes it is. Fire can burn faster in dry air and with lack of rain.

Andy : Hopefully the fire can be put down fast before it spread more. The smoke can cause lungs and throats irritation. It is very dangerous for children and elderly to breathe in such dirty atmospheres.

Brian : Yes it is very dangerous. The smoke hamper and disrupt transportations too.  Flight had to be cancelled and driving cars in smoke is very risky.

5. Write an explanation text about a natural phenomenon
Tsunami
Tsunami, or etymologically means "big waves in the harbor", is a large air wave caused by changes in the seabed, such as earthquakes. This disturbance creates waves that spread in all directions with wave speeds reaching 600-900 km / hr. Initially this wave has a small amplitude (generally 30-60 cm) so it is not felt in the high seas, but the amplitude enlarges when accessed on the beach. When it reaches the coast, sometimes tsunamis hit land in the form of giant walls (especially in large tsunamis), but the more common form is the sudden surface. Rising water levels can reach 15-30 meters, cause flooding with current speeds of up to 90 km / h, rise a few kilometers from the coast, and cause great damage and loss of life. The most common cause of tsunamis is earthquakes under the sea, especially those that occur in the subduction zone with a magnitude of 7.0 magnitude or more. Other causes are landslides, volcanic eruptions, and the fall of large objects such as meteors into the air. Geographically, most tsunamis occur in the Pacific Ring of Fire and Sumatra Trench area in the Indian Ocean. Tsunami risk can be detected by a tsunami early warning system that occurs large-magnitude earthquakes and conduct data analysis of sea air changes that occur thereafter. If there is a tsunami risk, the party can seek approval or take action such as an evacuation. The risk of damage can also occur by making tsunami resistant, such as building buildings with large space, and using reinforced concrete materials, and by connecting to the community about how to save themselves from tsunamis, such as moving and preparing contingency plans from afar.
