A seismogram is a visual record that is created by a seismograph. A seismograph is a piece of equipment that records earthquake movements. These two items go hand in hand and are essential for the study of earthquakes.Know More
Without a seismograph, there would be no seismogram. A seismograph detects movement in the Earth's crust, translating that movement through its inner workings to move a recording device, often a needle, that makes markings on what becomes the seismogram. The base of a mechanical seismograph moves beneath the hanging needle, and on the base rests paper. On the paper rests the needle, which should not move when the ground beneath it does. The resulting lines are a seismogram which can be read to understand information about the earthquake or movement, such as its intensity. Electronic seismographs produce printed seismograms. A seismograph can also be called a seismometer.
Seismographs and seismograms are also used to detect explosions, such as when a large bomb goes off, or volcanic activity. These items are used to detect not only how strong the vibrations are, but also to triangulate where the vibrations originate from. In other words, three seismographs in three different locations create seismograms that, when read correctly, can tell researchers where exactly the explosion or earthquake occurred.Learn more about Earthquakes
Kashmir lies on top of the area where the Indian and Eurasian continental plates collide. Immense seismic stress builds up in this area and is released through earthquakes and other seismic activity. On October 8, 2005, this release of stress caused an earthquake that resulted in the death of more than 80,000 people, thousands of injuries and catastrophic property damage.Full Answer >
The Kobe earthquake occurred because the town lies on the boundary between the Philippine and Eurasian tectonic plates, which rub against each other. The Eurasian plate is lighter than the Philippine plate, so the latter moves beneath the Eurasian plate, which in the case of the Kobe resulted in a shallow-depth-of-focus earthquake that was devastating.Full Answer >
The first earthquake to ever take place is unknown as it happened before the records of the events were kept. The first recorded earthquake was in 1769.Full Answer >
An adequate earthquake survival kit includes a first aid kit, a home survival kit, a car survival kit and a work survival kit. The first aid kit and home survival kit should have enough supplies to last for three days.Full Answer >
