A 5700-square-kilometer quiet zone occurs in the midst of the locations of more than 4000 earthquakes off the Pacific coast of Nicaragua. The region is indicated by the seismic gap technique to be a likely location for an earthquake of magnitude larger than 7. The quiet zone has existed since at least 1950; the last large earthquake originating from this area occurred in 1898 and was of magnitude 7.5. A rough estimate indicates that the magnitude of an earthquake rupturing the entire quiet zone could be as large as that of the 1898 event. It is not yet possible to forecast a time frame for the occurrence of such an earthquake in the quiet zone.
在尼加拉瓜太平洋沿岸4000多次地震发生地的中间位置,有一个面积为5700平方公里的平静区域。地震空区技术表明,该区域可能发生震级大于7级的地震。这个平静区域至少自1950年以来就一直存在;上一次源于该区域的大地震发生在1898年,震级为7.5级。粗略估计表明,使整个平静区域发生破裂的地震震级可能与1898年那次地震一样大。目前还无法预测这个平静区域发生此类地震的时间框架。
