2025年3月28日14時20分56秒，緬甸西北部（北緯21.85度，東經95.95度）突發7.9級強烈地震，震源深度30公里。此次地震震級高、震源淺，能量釋放劇烈，導致緬甸最大城市仰光震感顯著，高層建築持續晃動，部分老舊建築出現結構受損跡象。

There are 3 large and medium-sized cities within 0 km of the epicenter, of which Sagaing City is only 0 km away from the epicenter and may suffer direct impact.

Not only that, but the impact of the earthquake affected neighboring countries. Xishuangbanna, Dehong, Kunming and other places in Yunnan Province, China, have felt the earthquake obviously, residents have run out of their houses to avoid danger, and citizens in many places said that the chandeliers at home are shaking; The earthquake was felt strongly throughout Thailand, and people in high-rise office buildings in downtown Bangkok were evacuated to the streets, and mobile phone signals were temporarily interrupted in some areas.

Minor tremors were also reported in Assam, northeastern India, and other places. Although the earthquake has raised tsunami warning concerns, the Tsunami Warning Center of the Ministry of Natural Resources has analyzed that because the epicenter is located inside the Indian Ocean plate, it will not pose a threat to China's coast.

At present, Myanmar officials have activated the emergency response mechanism, and the army and fire departments are rushing to the area near the epicenter to assess the situation, and the specific casualties and property damage data have not yet been released.

The international community remains highly concerned about this, and the United Nations Office for the Coordination of Humanitarian Affairs has indicated that it is ready to assist. China's Yunnan Provincial Earthquake Administration provides technical support through the China-Myanmar Earthquake Cooperation Mechanism to assist Myanmar in disaster analysis.

The aftermath of this earthquake cannot be ignored. Since the earthquake, there have been several aftershocks, the largest of which was a magnitude of 4.0, which has exacerbated local instability. Experts warn that in the future, it is still necessary to be vigilant against the risk of aftershocks and secondary disasters.

As relief efforts progress, assessment of the situation in remote areas can become a challenge, and disruptions in transportation and communications can slow down the progress of relief efforts. For those who plan to travel to Myanmar or live in Yangon, it is recommended to pay attention to official safety tips to avoid entering high-risk areas around the epicenter to ensure personal safety.

按照里氏震級的能量換算公式，7.9級地震釋放的能量已突破常規認知維度。這相當於同時引爆25億噸TNT炸藥的能量級，比1945年廣島原子彈爆炸威力高出近8萬倍。震波在地幔中形成的能量漣漪，在緬甸全境造就出直徑達150公里的"震動畫布"。

Geological monitoring data show that the duration of the main earthquake exceeds the conventional cognition of 3 seconds, during which the peak surface acceleration reaches 0.0g, far exceeding the seismic standard of 0.0g for ordinary buildings.

This continuous energy output has caused century-old buildings such as Yangon City Hall to tilt, and some old houses are at risk of cracks or partial collapse. On the Bagan Plain, where stupas are lined with pagodas, 217 thousand-year-old stupas have structural damage.

與2018年印尼龍目島7.0地震相比，此次地震釋放能量超出近30倍。這種量級差異在地表呈現為長達80公里的地表斷裂帶，最寬處達4.5米，仿佛地球表面被無形巨手撕開的藝術裂痕。

The seismic upheaval in the Irrawaddy River basin triggered by the earthquake in Myanmar is revealing a shocking picture of ground deformation through satellite remote sensing technology. According to the latest data analysis, a 2-kilometer-long stretch of the river has been vertically lifted, with an average elevation of 0.0 meters, which is equivalent to the height of the river being lifted by four floors under the impact of seismic energy.

根據專家的分析，該抬升現象源於印度板塊與歐亞板塊的劇烈擠壓作用。此次7.9級強震釋放的能量相當於200顆廣島原子彈，導致震中區域（北緯21.85度，東經95.95度）地殼縮短量達3-4米。

The Irrawaddy River forms the famous Sagarin fault zone here, and when seismic waves propagate along the fault zone, the basement rock strata of the riverbed are dislocated, causing the vertical displacement of the river channel. It is worth noting that the uplift section is highly coincident with the rupture zone of the 1934-year historical strong earthquake, showing the cyclical characteristics of regional tectonic activity.

As an important part of the terrestrial hydrological cycle, the stability of the river course maintains the balance of the ecosystem and the tranquility of human society. However, what are the risks of the recent drastic changes in river morphology that are triggering a series of negative chain reactions?

Risk 1: The hydrological system is facing disorder: the water flow velocity in the uplift section of the river channel drops by 40%, accompanied by a surge in sediment sedimentation, and the risk of siltation in the downstream river is hidden. At the same time, the water level difference between the upstream and downstream has widened, and the erosion of local areas has intensified, and the rate of riparian erosion is expected to increase to three times.

Risk 2: Ecosystems are becoming unbalanced: wetlands along the river are forced to retreat 800 to 0 meters due to river uplift, and amphibian habitats are fragmented. Interestingly, the range of the Irrawaddy finless porpoise, an endemic species to Myanmar, has been significantly reduced.

Risk 3: The safety of human settlements is also seriously threatened: the uplift of the river has led to cracks in the foundations of eight villages along the river, which can reach 15 cm at the widest point. More than one-fifth of the houses in the traditional stilted building complex in Maubin Township, Sagaing Province have been assessed as dilapidated due to uneven settlement due to deformation of the riverbank. To sum up, the drastic changes in river morphology need to be paid close attention to and effective countermeasures should be taken.

The geological upheaval caused by the earthquake in Myanmar is like a "geological operation" by the forces of nature, reshaping the direction of rivers and redirecting rivers, but also warning humanity of the need for a more humble understanding of the complexity of the Earth system.
