What is an earthquake? An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface … Read more
The first seismograph was invented in 132 A.D. by the Chinese astronomer and mathematician Chang Heng. He called it an “earthquake weathercock.”Each of the eight dragons had a bronze ball in its mouth. Whenever there was even a slight earth tremor, a mechanism inside the seismograph would open the mouth of one dragon. The bronze … Read more
To begin with, according to U.S. Representative for Illinois’s 9th congressional district Jan Schakowsky an earthquake is “There is a lot that happens around the world we cannot control. We cannot stop earthquakes, we cannot prevent droughts, and we cannot prevent all conflict, but when we know where the hungry, the homeless and the sick … Read more
The Earth had formed over 4.5 billion years from now and since then, we are still seeing changes. We are seeing volcanoes erupting and earthquakes shaking the earth’s surface causing massive destruction, the causes is due to plate tectonics. The plate tectonic theory is the theory of the Earth’s outer shell is divided into several … Read more

There were thousands of aftershocks, about 1,874 of them were so large that they could be felt as far as Louisville, Kentucky, almost 190 miles away. It is unknown how many lives were … Read more
Earthquake is a violent and sudden shock of the earth, which is often caused by two layers of the ground slipping from one another. Earthquakes are measured in accordance with their magnitudes. The earthquakes with higher magnitudes have higher destruction levels. Scientists believe that earthquakes can occur anywhere, anytime, and are unpredictable. Although the engineering … Read more

Earthquake-proof Buildings After the massive earthquake near Japan one wonders if it’s possible to build an earthquake-proof building? The answer is yes and no. There are of course, engineering techniques that can be used to create a very sound structure that will endure a modest or even strong quake. However, during a very strong earthquake, … Read more
On Tuesday October 17, 1989 at 5:04 PM the Loma Prieta earthquake struck the San Francisco, Monterey Bay, and Silicon Valley areas. Those were no the only areas affected. Many areas up to 70 and 100 miles away could feel the tremble of the quake. The epicenter of the quake was in the Santa Cruz … Read more
Earthquake, shaking of the earths surface caused by rapid movement of the earths rocky outer layer. Earthquakes occur when energy stored within the earth, usually in the form of strain in rocks, suddenly releases. This energy is transmitted to the surface of the earth by earthquake waves. The study of earthquakes and the waves they … Read more
