波多黎各被5.8级地震击中

A 5.8 magnitude earthquake struck southwest Puerto Rico early Monday morning, causing cracks in homes and power outages.
It struck just south of the island at a depth of 6 kilometers (about 3.7 miles) below ground at 5:32 am, according to the U.S. Geological Service (USGS). Another quake measured at magnitude 5.1 struck later at 10:51 am.
The quake was nine miles from the coastal town of Guánica, where some homes were damaged. No major injuries were reported.
No tsunami warning was issued after the quake, but the USGS warned of more tremors and possible mudslides. People were warned to stay off the roads in the area to allow emergency personnel to assess the damage.
波多黎各位于北美和加勒比构造板的边界附近。在过去的几周中,同一地区发生了数百次小地震。
“The proximity of these events to Puerto Rico, and their shallow depth, mean that dozens of these events have likely been felt on land, though with the exception of the latest M 5.8 earthquake, none are likely to have caused damage,” the USGS said.
波多黎各的地震网络主任维克多·霍尔法诺(Victor Huerfano)告诉美联社,浅层地震发生在波多黎各西南地区的三个断层:拉贾斯山谷,蒙塔尔瓦角和瓜亚尼拉峡谷。
