若把地震分成小地震、中大地震，我暂且分成5级以上的地震为中大地震，7级以上为大地震。地震的震级是根据能量计算的，现在常用的里氏震级，若没记错的话。地震的烈度是地震对地面的破坏程度。而地震的破坏程度与地震的震源埋深有关，有浅源地震、中源地震、深源地震等等。
地震的机理虽然不完全清楚，但最后的能量、应力出口总是在地壳、地层的活动断裂处(活动断裂指是晚第四纪以来活动、至今仍在活动的断层，距今约3至10万年)。地球上，太平洋板块与欧亚板块，太平洋板块与北美板块相交叠处，最近异常活跃，远不说2008/5/12纹川8级大地震，2011/3/11的日本宫城9级大地震。
我刚刚从美国USGS 狗狗一下，在已过168小时，7DAY内，光5级以上的地震就有200多次，平均一小时不到地球就有一次5级以上的地震。
而这些5级以上的地震基本上全在JAPAN，即太平洋板块与欧亚板块碰撞的那条线上。请自己参看下面的引用DATA。狗狗翻译，不尽通顺，呵呵！
最新的5.0级地震+世界 - 过去7天
最新的地震震级5.0和更大的世界 - 最后7天
西班牙语版本
5级，由美国地质调查局，并在最后一周（168小时）网络中的贡献更大的地震。震级6及以上为红色。 （一些早期的事件可能会被遮蔽后来者在地图上。）
最近一次地震是在列表的顶部。时间是协调世界时（UTC）。单词“地图”点击看十度的高大的地图显示了地震。点击一个事件的“日期”来得到一个详细的报告。

地震震级
地震学家在表示地震的大小单位的数量级。有许多从地震震级是衡量，因为每个方法只在一个数量级，并与不同类型的地震仪不同的方式工作范围有限。有些方法是基于体波（其中旅游范围内的地球深部结构），有的表面波（其中主要是沿着地球的最上面层旅行）的基础上，和一些完全不同的方法为基础。然而，所有的方法旨在同意以上的范围和程度，他们是可靠的。
但现有数据不完整的程度有时初步估计和报告。例如，海啸中心将计算出初步规模的事件和地点，尽快提供足够的数据作出的估计。在这种情况下，时间是为了广播警告，如果海啸很可能是由事件产生的本质。这种初步的程度，这可能是由一个半级或以上的单位了，是在手的目的充足，是由规模更精确的估计取代了更多的数据变得可用。
地震震级是衡量地震大小的对数。简单来说，这意味着在相同距离的地震，摇晃将在一个5级为里氏4级地震的中大地震的10倍。由地震所释放的总能量，然而，上升了32个因素。

Earthquake Magnitude
Seismologists indicate the size of an earthquake in units of magnitude. There are many different ways that magnitude is measured from seismograms because each method only works over a limited range of magnitudes and with different types of seismometers. Some methods are based on body waves (which travel deep within the structure of the earth), some based on surface waves (which primarily travel along the uppermost layers of the earth), and some based on completely different methodologies. However, all of the methods are designed to agree well over the range of magnitudes where they are reliable.
Preliminary magnitudes based on incomplete but available data are sometimes estimated and reported. For example, the Tsunami Centers will calculate a preliminary magnitude and location for an event as soon as sufficient data is available to make an estimate. In this case, time is of the essence in order to broadcast a warning if tsunami waves are likely to be generated by the event. Such preliminary magnitudes, which may be off by one-half magnitude unit or more, are sufficient for the purpose at hand, and are superseded by more exact estimates of magnitude as more data become available.
Earthquake magnitude is a logarithmic measure of earthquake size. In simple terms, this means that at the same distance from the earthquake, the shaking will be 10 times as large during a magnitude 5 earthquake as during a magnitude 4 earthquake. The total amount of energy released by the earthquake, however, goes up by a factor of 32.
