1. How does the movement of a plate do this?

8. How do earthquakes happen?
Explain how an earthquake occurs (helpful words might be pressure, tension, breaking crust sudden, release etc)
Draw a diagram to that show the following features :
Focus
Epicenter
Seismic Waves
( Wider World p270 has diagram and explanation from Kobe which is helpful)

10. How to measure the magnitude (strength) of an earthquake
Richter Scale

11. Liquefaction
Liquefaction happens when an earthquake shakes wet soil. The water rises to the surface and turns solid soil into liquid mud. Buildings then sink into this mud.

12. It was an undignified thing to happen to a block of flats
It was an undignified thing to happen to a block of flats. Japan is an earthquake-aware country, and when apartment complexes were built in the Kawagishi-cho area in the city of Niigata, they were sturdy reinforced concrete. But after a magnitude 7.5 shock on 16 June 1964, it was not the structures that gave way but the ground beneath them. Hundreds of buildings tilted like ships listing in heavy seas, victims of soil liquefaction. When the time came for repairs, some of the buildings were simply winched back upright.

13. Tsunami
A Tsunami is a large wave of seawater that can travel for thousands of miles and is triggered by an underwater earthquake.

15. New Tsunami, Yesterday 6.0 magnitude earthquake hits Indonesia
(AFP) – 2 hours ago
JAKARTA — A strong 6.0-magnitude earthquake hit Indonesia's Java island on Tuesday, seismologists said, but no tsunami warning was issued.
The quake struck 147 kilometres (91 miles) southeast of Sukabumi at a depth of 13 kilometres, at pm (09:59 GMT), the Meteorological and Geophysics Agency said.
"There are no reports on damage or victims so far. We felt the quake only briefly and there was no panic here," Cianjur police chief Wibowo said.
The town of Cianjur is close to Sukabumi.
"The quake occured on the sea. It's the tsunami we were afraid of. But there is no tsunami warning," he said.
Indonesia sits on the Pacific "Ring of Fire", where the meeting of continental plates causes high volcanic and seismic activity.
