She was shaken from her sleep in her sleep in her home as a earthquake caused a mountain.
caused a mountain.整个作earthquake的后置定语吗?

这个句子完整吗?个人认为此句不完整.或者是caused后缺少by或者其他介词,或者是mountain后缺少东西
再问： 原句是这样的：Like millions of other Southern California residents she was shaken from her sleep in her normally tranquil foothill community home as a large earthquake caused a mountain located just 30 miles away to grow nearly 15 inches higher all in a matter of seconds.
再答： 这样看来，你的理解有误。earthquake的后置定语并非caused a mountain, 而是caused a mountain located just 30 miles away to grow nearly 15 inches higher all in a matter of seconds。 句意为：致使一座30英里远的山在几秒钟的时间里增高近15英尺的地震。
