why do you think earthquakes appear in the places they do?
5. Deep earthquakes were discovered in the 1920s, but they remain a subject of contention today. Earthquake-triggered landslide in China (2008), collapsed freeway in San Francisco (1989) and toppled building in Taiwan (1999) An earthquake is the shaking of the ground cause by seismic waves. a. The world's greatest earthquake belt, the circum-Pacific seismic belt, is found along the rim of the Pacific Ocean, where about 81 percent of our planet's largest earthquakes occur. Earthquakes can strike any location at any time, but history shows they occur in the same general patterns year after year, principally in three large zones of the earth:.

What ideas do you have about why some earthquake and volcano data do not fit the patterns you observed? 4. Earthquakes are caused when tectonic plates shift and push over each other. Yet they account for more than 20 percent of …

How do patterns in earthquake and volcano data compare? answer to Why do large earthquakes appear on subduction zones? The Ring of Fire is located along the edges of a major tectonic plate. Earthquakes happen along the edges of tectonic plates and fault lines and there are three large zones on our planet which are most susceptible to earthquakes. Earthquakes and volcanoes occur in the same places because they both happen along the Ring of Fire.

6. Earthquakes. The reason is simple: they aren't supposed to happen. The devastating 7.0 earthquake hitting Haiti in January 2010 and took away more than 200,000 precious lives, the massive 8.2 magnitude earthquake in Fiji in August, the 7.5 earthquake in Indonesia in September, and a 7.9 magnitude earthquake in Fiji during September, all make us shudder. What ideas do you have about why there are patterns in earthquake and volcano data? 7. These are the Circum-Pacific Seismic Belt, the Alpide Belt, and the Mid-Atlantic Ridge. An earthquake is one of the worst natural disasters on our earth.We think that the ground we stand on is very stable, but it isn’t.It moves quite a lot. Where Earthquakes Occur The Earth is formed of several layers that have very different physical and chemical properties. The outer layer, which averages about 70 kilometers in thickness, consists of about a dozen large, irregularly shaped plates that slide over, under and past each other on top of the partly molten inner layer. Why do you think earthquakes appear in the places they do? The Driving Question for this unit is How Is the Earth Changing? In the last few decades scientists have been able to find out why earthquakes happen.. Earthquakes happen when there is a sudden vibration in the earth’s crust.It’s like a large lorry that travels down your street. Almost all earthquakes occur when pent up stress in rocks along large, active faults (like the SAF) is suddenly released as the rock breaks.

Most earthquakes occur at the boundaries where the plates meet.
