my reflections on the first few weeks of lessons and discussing.

week 4 reflection

We have currently chosen our main focus on Natural Disaster which are Tsunamis and Earthquakes since they are some how similar in their causes.We have also came out with some important guiding questions like :
1. What is a tsunami or an Earthquake?
2. How are they caused?
3. How often and where do they usually occur?
... and much more.

However we have not decided on how we would present about our project and what suitable resources we should get information from.

We have also found out that

1. A natural disaster is the consequence of a natural hazard which affects human activities
2. Tsunamis and earthquakes has quite a close relationship as most tsunamis (recorded by history) are caused by earthquakes.
3.A tsunami is a series of waves created when a body of water, such as an ocean, is rapidly displaced.
4. Earthquakes that are above or below sea, volcanic eruptions and landslides can lead to potential tsunamis.
5. Pacific Tsunami Warning and Mitigation System (PTWS) is a precaution of tsunamis.
6. The objective of the PTWS is to detect, locate and determine the magnitude of potential tsunami earthquakes occurring in the Pacific Basin or its immediate margins.
7. After PTWS confirmed a tsunami
-A tsunami warning is issued to warn of an imminent tsunami hazard
-The warning includes predicted tsunami arrival times at the selected coastal communities and distance the tsunami could travel in a few hours 
-The National Oceanic & Atmospheric Administration (NOAA) Weather Radio System then provides direct broadcast of tsunami information to the public.
thats all we've covered till now...
