There’s no doubt that earthquakes can be powerful, and usually the bulk of that power goes to destroying things.
Typical, earthquake sensors are powered by battery, but Daniel Tomicek’s prototype is very low-powered and can make due with just the energy created by swaying buildings. When earthquakes occur, the energy harvested from the vibrations activates the wireless transceiver to transmit the data packets which contain the sensor’s identifier.
Joseph Gordon-Levitt has left the anticipated adaptation of Sandman, citing creative differences between his vision of the film and that of New Line Cinemas. Scientists from the University of Chicago have taken a look at the Curious Marie, a bit of meteorite containing perhaps the most valuable ceramic in the world. Although the ground we walk on seems completely solid, the Earth is actually made up of huge pieces of flat rock called tectonic plates.
When these plates rub together, the movement forces waves of energy to come to the earth's surface. Earthquakes can make buildings fall down and set off landslides, as well as having many other deadly effects.
Almost 80% of all the planet's earthquakes occur along the rim of the Pacific Ocean, called the "Ring of Fire"; a region that encircles the Pacific Ocean and is home to 452 volcanoes (over 75 percent of the world's active and dormant volcanoes). A Richter Scale is a device that gauges the magnitude (the energy it generates) of the earthquake.
It is important for earthquake-prone countries such as Japan to build houses and buildings that react well to earthquakes. The epicentre of an earthquake is the area on the surface, above the point where the earthquake originated. The hypocentre of an earthquake is the area below the earth’s surface; it is the place where the earthquake began.
A tsunami is a sequence of huge waves of water that usually occur in oceans or large lakes. There are about 500,000 earthquakes a year around the world, as detected by sensitive instruments. An earthquake is what happens when two blocks, or ‘plates’ of the Earth suddenly slip past one another. While the edges of faults are stuck together, and the rest of the plate keeps moving, the energy that would normally cause the blocks to slide past one another is being stored up. The seismic waveforms generated during a quake depend on many factors including including fault geometry and rock type, wave travel path, soil composition, nearby mountains and other geological structures, and location of the origin of the quake.The interaction of an earthquake with a structure is modeled by engineers, particularly civil or structural engineers, to produce the Response Spectrum for that particular quake. While you can’t stop an earthquake from quaking earth, a Victoria University student has found a way to divert some of that energy to monitoring the quake it came from. The greater the vibrations, the greater the energy harvested and the more packets that are sent.
Adult Swim's fantastic show Rick and Morty is coming back to television by the end of 2016, and will include more episodes than originally anticipated!
These ceramic elements can tell us whether the early universe created heavy particles -- without containing any of those elements.
An earthquake that occurs at the bottom of the sea can push water upwards and create massive waves called tsunamis.
You are unlikely to feel a magnitude 3 earthquake but magnitude 6 earthquakes could potentially cause large damage. More recently, an earthquake that hit the Tohoku region of Japan on March 11, 2011, had a magnitude of 9.0 and killed over 15000 people.
Good engineering can help stop buildings collapsing under the stress of large earthquakes, for example by building structures which can ‘wobble’ when an earthquake hits.
When he was angry, Poseidon would strike the ground with his trident and set off an earthquake. Other scientists think that animals may sense electrical signals set off by the shifting of underground rocks.
The speeds of the seismic waves enable scientists to locate the epicentre of an earthquake.

The worst affected areas include; Japan, China, the Philippines, Indonesia, Australasia and the West coast of North and South America. Tsunamis are caused by disturbances within the surrounding areas; they are usually caused by underwater earthquakes, volcanic eruptions and landslides. The instrument uses a weighted pen and a spring and the vibrations from the earthquake makes the pen draw lines onto some paper. The Response Spectrum is a measure of how much a structure will respond to that particular earthquake and depends on the stiffness and mass of the structure and its damping. Earthquakes can sometimes be nothing more than small tremors or shakes, but sometimes they can cause damage and devastation. A tsunami is not a tidal wave – these are caused by the forces of the moon, sun, and planets upon the tides, as well as the wind as it moves over the water. Each year, the southern California area alone experiences about 10,000 earthquakes, most of them not felt by people. Rather, because oil generally is found in soft and squishy sediment, when oil is removed other rock moves in to fill the space left behind, creating mini earthquakes that are not noticeable to humans. The location below the earth’s surface where the earthquake starts is called the hypocentre, and the location directly above it on the surface of the earth is called the epicentre. But this layer is not all in one piece – it is made up of many pieces like a jigsaw puzzle covering the surface of the Earth.
The energy radiates outward from the fault in all directions in the form of seismic waves like ripples on a pond. A short wiggly line that doesn’t wiggle very much means a small earthquake, and a long wiggly line that wiggles a lot means a large earthquake. Scientists also talk about the intensity of shaking from an earthquake, and this varies depending on where you are during the earthquake. When an engineer wishes to perform a test on a structure in the laboratory, he or she defines a Required Response Spectrum, or RRS.
Other risks involve consequences to the landscape, environment and wildlife along with the risk of landslides and tsunamis.
These puzzle pieces keep slowly moving, sliding past one another and occasionally bumping into each other. The seismic waves shake the earth as they move through it, and when the waves reach the earth’s surface, they shake the ground and anything on it. The length of the wiggle depends on the size of the fault, and the size of the wiggle depends on the amount of slip. This RRS can then be used to create a motion in the lab to simulate a quake based on its particular wave patterns, allowing for further study through the reproduction of the original motions.
We call these puzzle pieces tectonic plates, and the edges of the plates are called the plate boundaries. The plate boundaries are made up of many faults, and most of the earthquakes around the world occur on these faults. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. Finally, when the plate has moved far enough, the edges unstick on one of the faults and there is an earthquake. ANCO’s seismic shake tables are used to simulate the vibrations of an earthquake in a safe and controlled manner. These tables can move in three dimensions and vibrate to realistically reproduce earthquake motions and the RRS. This simulation is useful for the investigation of engineering problems related to maintaining safety during an earthquake.
This includes ensuring the stability of structures such as hanging fixtures, the attachment of shelving and other fixtures to walls, and ensuring that any furniture present will not tumble about in the event of an earthquake or any moderate to severe vibrational force.In industry, for example, shake tables are used to assure that the safety equipment in a nuclear power plant will perform correctly during and after an earthquake. LabVIEW is used to play a series of recorded earthquakes through the table to show how variable they are. The engineers took advantage of LabVIEW’s spectral analysis capabilities to generate waveforms of a quake based on an experimentally recorded RRS.

The generated waveform is then put through filters and other signal processing to produce a more accurate model of earthquake motion. During the vibrational simulation of an earthquake, this video can be projected onto a screen and the audio can be played back to create a more immersive experience for any onlookers. A GUI (graphical user interface) allows for the use of this software control with relatively little training. To further keep control of the system simple, a library of approximately 50 earthquake scenarios can be dragged and dropped to form short sequences up to several minutes in length. Motor C, connected to the lower motor, runs continuously to move the surface in the horizontal direction.
Motors A and B are connected to the upper motors, and their directions at first match, then rotate clockwise, then rotate counterclockwise.
Changing the motor power over time, for example, could create interesting variation in the simulation. In the program shown below, three random number generators output a number between 25 and 75.
The following program consists of quick changes in direction of both motors A and B, while motors A and B are always moving in the same direction at any given time. This is looped to emulate a slower version of the vibrations caused by seismic waves during an earthquake. It undulates in a wavelike fashion, moving at times back and forth and at times lifting one side of the platform higher than the other. However, since the power is variable, the rate of motion of the upper two motors varies randomly. The movement of this simulated quake is much less regular than that of version 1, at times bursting forth in quick motions and at other times going much more smoothly and slowly. A large ball is placed in a cage made of netting, while a vine hangs off of a rigid part of the netting structure.A chain is attached to a rigid part of the netting structure and is anchored at its opposite end to the brick platform. The scene includes two windows, two minifigures, a ladder propped on a window, a snake, and two pieces of greenery.
During the simple vibrational motion, the ladder falls off of its place on the window quickly, and knocks one of the minifigs off of the platform as it continues to slide. This scene includes a large bay window, two minifigures, a snake, two pieces of greenery, and a ladder. A minifigure quickly tumbles backwards off of the platform, soon followed by the ladder, shrub, and second minifigure.
The bay window tumbles off, and the second piece of greenery soon slides off the platform, accompanied by the snake.
This demonstrates how lack of sound attachment of objects affects their ability to remain stable during earthquake-like circumstancesWhile the LEGO version of the shake table is nowhere near as precise as an ANCO manufactured shake table, it still provides students with the ability to model simple vibrations.
The effects of these vibrations can be seen when the NXT programs are run and a platform is used with the test objects placed on its surface. The effect of changing variables on the stability of objects on the simple shake table can be demonstrated and tested. Some variables that can be tested include mass, shape, size and method of attachment to the platform.
A magnitude of 3-4 can be felt near the epicenter and is a moderate quake, whereas a magnitude of 6-7 can be largely destructive and is a major quake that can be felt for tens of miles around the epicenter. The earthquake energy injected into a structure is eventually dissipated to heat, minor scraping and deformation, and sound. RRS – required Response Spectrum, or the peak response of a building or structure to an earthquake, depending on its resonant frequencies and damping.
