The Sagaing Fault, deadly earthquake and volcanoes in Myanmar: Geodynamic perspectives

Abstract

The Sagaing Fault is a prominent, right-lateral strike-slip fault that extends approximately 1,400 kilometers through central Myanmar. The Fault is one of the most seismically active fault systems in world, with a history of producing large and devastating earthquakes including recent 7.7 earthquake that struck near Mandalay. Although the primary cause of the earthquake is regarded as being the result of a rupture that occurred along the Sagaing Fault due to the Myanmar plate and Sunda plate sliding horizontally past each other, we here discuss the other geodynamic factors on the deadly nature of the Earthquake. Preparedness in advance is key to staying safe and reducing the damage caused by natural hazards. Ongoing scientific research and regular monitoring are also crucial for spotting early warning signs of natural hazards like earthquakes, landslides, and volcanic eruptions. Given the easy accessibility along the Sagaing Fault and volcanoe area such as the Mt. Popa region, further integrated research combining seismic, volcanological, petrological and tectonic studies is strongly encouraged and highly warranted.
