Chapter 7 Cretaceous geology of Myanmar and Cenozoic geology in the Central Myanmar Basin

The January 11, 2018, Mw 6.0 Bago‐Yoma, Myanmar Earthquake: A Shallow Thrust Event Within the Deforming Bago‐Yoma Range

“…As shown in geological maps of the BYR region (Than et al, 2017), and subsurface data of CMB area from Pivnik et al (1998), the primary structures with both areas are intercepted by a series of shorter faults with E-W orientations. These cross faults within the BYR and CMB area may act as the conjugate faults co-developed with the primary inversion structures since the beginning of the oblique plate convergence.…”

“…Bertrand and Rangin (2003) proposed that a regional plate kinematic reorganization occurred during the Miocene which served as a transition between the transtensional tectonic regime related to the opening of the CMB and the transpressional tectonic regime related to the inversion of the CMB. Along the eastern CMB, Than et al (2017) suggested that the area underwent two tectonic phases; a compressional phase during the late Miocene that formed the anticlines and synclines in the Pegu formations, followed by strike-slip movement along the Sagaing Fault that resulted in en echelon faulting. In general, most authors agree that the inner Burma plate has been subjected to approximately E-W compression since the late-Miocene, which formed the structures observed in and around the CMB.…”

New Insights Into Active Faults Revealed by a Deep‐Learning‐Based Earthquake Catalog in Central Myanmar

“…Monywa and Mt. Popa; Than et al., 2017). The Monywa volcano has the most recent eruption records in the Holocene, which formed a series of maars (Belousov et al., 2018; Maury et al., 2004).…”

Insights into the tectonics in Myanmar from new high-resolution and integrated focal mechanism catalogs

“…occurred in the footwall of the rupture fault, but also with fault orientation almost normal to the strike of the Sagaing Fault and other regional structures. As shown in geological maps of the BYR region(Naing Maw Than et al, 2017), and subsurface data of CMB area fromPivnik et al, 1998, the primary structures with both areas are intercepted by a series of shorter faults with E-W orientations. These cross faults within the BYR and CMB area may act as the conjugate faults co-developed with the primary inversion structures since the beginning of the oblique plate convergence.…”

“…The northwestern and southern segments of the BYR merge into the Salin and Prome subbasins, respectively (Pivnik et al, 1998). The BYR has been interpreted as an anticlinorium within the larger synclinorium of the CMB, with outcrops exposing Miocene sandstones and shales (Naing Maw Than et al, 2017). Geomorphic and geological studies show predominantly NNW-SSE and NW-SE linear structures (Bender, 1983;Ridd & Racey, 2015;Sloan et al, 2017).…”
