(Because these cities are) Located near the edge of Earth’s huge, shifting plates, these cities face the risk of death. 省略括號裡面的東西對嗎?

eg:-located---Being located-------
The standard participle usage can be omitted if the same subject involved.
=(Because these cities are);
(1)Located near the edge of Earth's hugh, shifting plates, these cities face the risk of death.
(2)Being/Having located near the edge of Earth's huge shifting plates, these cities face the risk of death.

Because they are located near the edge of Earth's huge, shifting plates, these cities face the risk of death.
=/= Being located near the edge of Earth's huge, shifting plates, these cities face the risk of death.
Located near the edge of Earth's huge, shifting plates, these cities face the risk of death.
「副詞子句」可以改寫成「分詞構句」的方式，它們都是述部的修飾語。不必想成是省略了什麼，而應想成是不同的寫作方式。因為它們在語意上有時並不完全相同：寫成because ....是有絕對的因果關係，但寫成(being) located ....則沒有那麼明確的因果關係，只是同時並存而己（宜用and連結：These cities are located near the edge of Earth's huge, shiting plates, and they face the risk of death.）

此外，分詞構句的主詞如果與主詞不同時，可寫出來。如：
The day being fine, we decided to go swimming.
= The day was fine, and we decided to go swimming.

這是標準分詞構句用法，因前後主詞一致可省略。所以是正確。
