When you call my name it’s like a little prayer
I’m down on my knees, I wanna take you there
In the midnight hour I can feel your power
Just like a prayer you know I’ll take you there — MADONNA
Earthquake, tsunami, nuclear explosion happened in Japan shocks the whole world! But Japan, we can feel your power! Many people are dead, homeless, exhausted, but the Japanese never get desperate! They are calm, brave and united.
After the disaster struck, the balance of the planet is even shifted according to a geological survey. The quake caused a rift 15 miles below the sea floor that stretched 186 miles long and 93 miles wide. The areas closest to the epicenter of the quake jumped a full 13 feet closer to the United States.
Why Japan earthquake has such destructive power and how Japan tsunami become an accomplice after the earthquake? The flash animation below about earthquake focus and tsunami formation may explain everything.
This simple Flash animation shows the relationship between earthquake focus and earthquake epicenter which is found directly above the focus. Also displayed in the animation are the fault plane, fault scarp, and fault trace.
Then we come to know what does it take to form a tsunami. The flash animation below illustrates the steps involved in producing a tsunami. First, motion along a submerged fault plane causes a column of water to rise directly above the epicenter. As the wave approaches the shore, it slows, wave height grows, and wave crests grow closer together. The heightened wave then reaches the shore and can extend far inland, destroying everything in its path. Tsunami-like waves can also be caused by underwater landslides.
Be strong, Japan! We pray for you!
