据国家地震台网官方微博消息，1月20日23时48分，中国地震台网正式测定马里亚纳群岛发生6.1级地震。震源深度为190千米，位于北纬18.45度，东经145.60度。
马里亚纳群岛位于西太平洋北部，包括关岛、北马里亚纳群岛和南马里亚纳群岛等岛屿。由于该地区靠近板块边缘，地震活动较为频繁。此次地震的震级较高，但目前尚未收到人员伤亡和房屋损坏的报告。
中国地震台网表示，将密切关注此次地震的动态变化，及时发布相关信息。同时，也提醒广大民众在地震发生时要注意保护自身安全，尽量避免到高楼大厦、地下室等危险区域避险。
据了解，马里亚纳群岛曾经发生过一次更为严重的地震，即2015年5月27日发生的“珍珠港大地震”，震级达到了9.0级，给当地带来了巨大的灾难性影响。因此，此次6.1级地震虽然规模较小，但仍引起了人们的关注和警惕。
总之，这次马里亚纳群岛发生的6.1级地震虽然震级不高，但仍需要引起足够的重视。我们应该时刻保持警惕，加强自我保护意识，共同应对自然灾害带来的挑战。

Title: Magnitude 6.1 Earthquake Strikes Mariana Islands, with a Depth of 190 Kilometers
Keywords: Mariana Islands, Magnitude 6.1 earthquake, Depth of 190 kilometers
News content: According to the official Weibo account of the National Earthquake Network, at 23:48 on January 20, China’s Earthquake Network officially confirmed that a magnitude 6.1 earthquake had struck the Mariana Islands. The depth of the epicenter was 190 kilometers, and it was located at 18.45 degrees north latitude and 145.60 degrees east longitude.
The Mariana Islands are located in the northern Pacific Ocean and include islands such as Guam, the Northern Mariana Islands, and the South Mariana Islands. As this region is close to the edge of a plate boundary, seismic activity is relatively frequent. This earthquake has a high magnitude, but no reports of casualties or damage to buildings have been received yet.
The China Earthquake Network said it will closely monitor the dynamic changes of the earthquake and release relevant information in a timely manner. At the same time, it also reminded the public to pay attention to their own safety during an earthquake and try to avoid dangerous areas such as high-rise buildings and basements.
It is understood that the Mariana Islands have experienced a more severe earthquake before, namely the “Pearl Harbor Great Earthquake” on May 27, 2015, which reached a magnitude of 9.0 and brought tremendous catastrophic effects to the local area. Therefore, although this magnitude 6.1 earthquake is smaller in scale, it still attracts people’s attention and vigilance.
In summary, this magnitude 6.1 earthquake that occurred in the Mariana Islands requires sufficient attention despite its low magnitude. We should always be vigilant, strengthen our sense of self-protection, and work together to cope with the challenges posed by natural disasters.
