The table can be coded in LEGO MINDSTORMS. So far, we have developed MINDSTORMS EV3 code for a random earthquake simulator and for one that starts slow and ramps up to top speed. Building the shake table itself is an exercise in using gear trains, translating rotational motion into linear motion, and combining power …

Step 1: Attach the two 2 x 4s to the edges of the plywood with drywall screws and place the ceiling hooks 5" in from the edge of the plywood and centered on the 2 x 4s (Fig. 5). Step 2: After assembly is complete, the table should be secured on top of the base by hooking 2 large rubber bands around each pair of hooks.

In most situations, if you feel shaking or get an earthquake alert, immediately: DROP where you are, onto your hands and knees. This position protects you from being knocked down and reduces your chances of being hit by falling or flying objects. COVER your head and neck with one arm and hand. If a sturdy table or desk is nearby, crawl ...

The rocky surface of Earth is a thin outer shell, much thinner than the other layers. The crust is made up of tectonic plates, which are in constant motion. The land that we see, or continental crust, is about 30 kilometers (19 miles) thick. Under the sea, oceanic crust is much thinner (8 to 10 kilometers, or 5 to 6 miles thick).
