New earthquake geology and soils research along several faults within the central Basin and Range Province in Nevada (USA) indicate slow rates of deformation (<0.15 mm/yr). 🔗 Read now: seismica.library.mcgill.ca/a…

Definitely, the Legaspi Lineament! I’m taking this as a sign that we should fast-track our paper on that fault.

In Temblor's latest, @phivolcs_dost scientists explore recent earthquake swarms off the shores of the southern Philippine island of Mindanao, and compare what's happening to the devastating 1976 Moro Gulf earthquake. temblor.net/earthquake-insig…

Ayon sa bagong pag-aaral ni Deo Carlo Llamas, isang geologist sa Philippine Institute of Volcanology and Seismology (PHIVOLCS) at Mario Aurelio, isang propesor sa University of the Philippines Diliman - College of Science - National Institute of Geological Sciences (UPD-CS NIGS), na ilang residente sa bayan ng Dimasalang, Palanas, at Cataingan sa Masbate Island ang nakatira malapit sa fault line. Tumama ang magnitude 6.2 na lindol sa Masbate Island noong Pebrero 15, 2003. At 17 taon matapos ang insidente, ito ay sinundan ng isang magnitude 6.6 na lindol sa parehong fault sa isla noong Agosto 18, 2020 na nagdulot ng surface rupture, landslides, at local tsunami ang parehong lindol. “This observation — that the rupture occurred at the same location as before — underscores the critical importance of active fault mapping for assessing ground rupture hazards,” saad pa ng mga experts. #PilipinasToday #Masbate #Lindol

#OnThisDay in 1990, the Digdig segment of the Philippine Fault generated a M7.8 earthquake in Luzon, producing a ~125 km surface rupture with ~6m maximum left-lateral offset. Thirty-four years later, we revisited a section of the rupture and found the fault offsets still visible

Updated Optical image correlation using Sentinel-2 data N-S displacements along the Sagaing Fault suggest a surface rupture of approximately 500 km — unusually long fault rupture for a magnitude 7.7 earthquake! The maximum ground offset reaches more than 4 m. -DETect Faults
