scary, right?
Gigantic waves that can level coastal communities demonstrate nature’s enormous power. Tsunami sprung from disturbances underneath the ocean such as volcanic eruptions and earthquakes. They may also occur after a huge meteorite impact or a nuclear testing where large amount of water are displaced, creating a ripple effect that reaches the shore. Man-made tsunami is possible although it is not as strong and massive as the one caused by nature.
Okay, now some few things about how tsunami works:
 |
| This is tectonic plate boundary before earthquake. |
 |
| Overriding plate bulges under strain, causing tectonic uplift. |
 |
| Plate slips, causing subsidence and releasing energy into water. |
 |
| The energy released produces tsunami waves. |
Signs of Tsunami
The first indication that a tsunami is about to happen is the occurrence of earthquakes. People living in the coastal areas need to be aware of the danger of tsunami whenever tremors are felt beneath the earth. Sometimes the epicenter of an earthquake is so distant that only slight earthquakes are felt. However, this may mean a huge tsunami is on its way, so it is good advice to evacuate as soon as possible to a higher elevation far from the shore.
For Malaysia, we are fairly safe from this catastrophic event (we'll talk about this in the next post). I said fairly, so there are still a few possibilities that it might occur.
So, untill next time.
