On November 12, at 22:41, Maldro Gongkar County in Lhasa, Tibet, experienced a mild earthquake of 3.4 magnitude, as confirmed by the China Earthquake Networks Center (CENC). This article delves into the details of this seismic event, including precise parameters, location, depth, and the historical context of earthquakes in this region over the past five years.
Key Details of the 3.4 Magnitude Earthquake in Maldro Gongkar County
According to official data from CENC, the earthquake’s parameters are as follows:
- Magnitude: 3.4 on the Richter scale
- Time: November 12, 22:41
- Location: Mozhugongka County, Lhasa, Tibet
- Coordinates: 29.82° N latitude, 92.26° E longitude
- Depth: 10 kilometers (shallow earthquake)
Geographical and Seismological Significance of Mozhugongka County
Maldro Gongkar County, located within the greater Lhasa region, sits in an area that is no stranger to seismic activity. Its geographic position within the Tibetan Plateau makes it prone to tectonic shifts, resulting in frequent minor earthquakes. Although this event measured at a moderate magnitude, the shallow depth of 10 kilometers could increase the perceived intensity at the surface.
Historical Seismic Activity in Maldro Gongkar County
In the past five years, the 200-kilometer radius surrounding the epicenter has experienced a total of 18 earthquakes of 3.0 magnitude or higher, highlighting the area’s seismic vulnerability. Notably, on November 7, 2024, just days before this recent earthquake, Maldro Gongkar County recorded a stronger 4.5 magnitude earthquake, situated only 3 kilometers from the November 12 epicenter. This recent activity indicates a pattern of seismic occurrences that may be linked to larger tectonic movements within the region.
Implications for Locals and Infrastructure
Though a 3.4 magnitude earthquake typically causes minimal damage, repeated events in proximity raise concerns for residents and infrastructure. The cumulative effect of frequent seismic events can weaken structures over time, increasing the potential for damage in the future, larger earthquakes.
The 3.4 magnitude earthquake in Mozhugongka County serves as a reminder of the natural seismic activities common to the Tibetan Plateau region. By examining both the current event and historical patterns, residents and authorities can better prepare for potential future incidents.

Understanding the Earthquake Activity in Maldro Gongkar County: Is It Unusual?
The recent increase in earthquake activity in Tibet’s Maldro Gongkar County has raised questions about the region’s seismic stability. To assess whether these earthquakes fall within normal patterns, it is essential to analyze recent activity, historical patterns, and the area’s unique geological features. Here’s a closer look at what the recent seismic uptick may mean and why the region’s geology makes it prone to earthquakes.
Historical Earthquake Patterns in Maldro Gongkar
In the past five years, Maldro Gongkar County and its surrounding 200 km radius have experienced 17 earthquakes of magnitude 3 or above. Most of these earthquakes were of relatively low magnitude, with the strongest being a recent 4.5-magnitude event on November 7, 2024. This history suggests that while seismic activity is periodic in the area, these events have typically been moderate, indicating a stable yet active seismic environment.
The area’s geological history, characterized by tectonic shifts over millennia, contributes to its ongoing seismic activity. Although the recent frequency of earthquakes appears to be rising, past data shows that the region regularly experiences minor to moderate earthquakes, making these events a relatively normal aspect of life in Maldro Gongkar.
Recent Spike in Earthquake Frequency and Intensity
The end of October through early November has seen a notable increase in earthquake frequency, including several quakes close in succession. Starting on October 21, 2024, with two earthquakes of magnitude 3.2 and 3.1, activity continued with multiple moderate quakes, culminating in the 4.5-magnitude earthquake on November 7. This earthquake, while not extreme, stands out due to its intensity within the recent spate of smaller tremors.
Most of the quakes, however, were below magnitude 4.5, categorized as small to moderate events. Though the uptick is noticeable, the range of magnitudes and the ongoing tectonic pressure make such seismic fluctuations a common occurrence for this tectonically active region.
The Geological Structure of Maldro Gongkar County
Located near major fault lines created by the tectonic collision between the Indian and Eurasian plates, Maldro Gongkar’s active tectonic environment inherently makes it prone to frequent seismicity. The region’s complex geological composition, marked by significant crustal movements and past volcanic activity, further contributes to its seismic potential.
Unique Geology and Rock Formations
Maldro Gongkar’s geology is rich and varied, with a diverse array of rock types. The area contains igneous rocks formed from volcanic activity, as well as sedimentary rocks that accumulated over millions of years. These rocks reveal crucial information about the area’s geological evolution and help geologists understand the region’s susceptibility to earthquakes.
Specialized Stratigraphic Layers: Maldro Gongkar is home to the Monla Formation, a unique stratigraphic layer made up of clastic rocks interspersed with limestone. This formation reflects shifts in crustal movement and sediment deposition, highlighting the area’s complex geological past.
Tectonic Structures and Seismic Activity
The region’s tectonic landscape is shaped by prominent folds and fault lines:
- Folds: The Maldro Gongkar-Emariji syncline, a major east-west fold, is one of the area’s defining geological features. This fold’s unique structure and wave-like formations hint at the region’s history of crustal movement.
- Fault Lines: Multiple fault lines intersect the area, including east-west, north-south, and diagonal faults. These fault lines play a crucial role in determining the distribution and frequency of earthquakes, adding to Maldro Gongkar’s seismic potential.
Volcanic and Magmatic Activity: A Dynamic Region
As part of the Gangdise volcanic belt, Maldro Gongkar has experienced extensive volcanic and magmatic events over time. This volcanic belt contributes to a diverse array of volcanic rocks that line the northern and southern boundaries of the syncline, creating unique rock formations.
Intrusive Rocks: Intrusive rocks, including granodiorite and granite, are found in the central and southern sections of the Jia-Ma-Ri basin, often forming complex rock structures. The presence of these rocks points to a history of volcanic activity, which has shaped the region’s geological makeup and contributed to its seismic sensitivity.
Conclusion: A Region with Geological Richness and Seismic Sensitivity
In summary, Maldro Gongkar’s complex geological and tectonic setting naturally predisposes the area to frequent, moderate earthquakes. While the recent rise in earthquake activity is notable, it generally aligns with the region’s historical patterns. The intricate rock formations, extensive fault lines, and active tectonic background suggest that moderate seismic activity is expected in this area.
To ensure public safety, continuous monitoring of Maldro Gongkar’s seismic activity remains crucial, as it allows for better preparedness in a region where geological factors contribute to the risk of earthquakes. This vigilance is essential for managing risks and protecting the well-being of the community in this seismically active landscape.
