Magnitude 7.3
18km (11mi) SE of Kodari, Nepal
27.837°N   86.077°E
depth=15 km (9.3 mi)

USGS: “This earthquake occurred as the result of thrust faulting on or near the decollément associated with the Main Himalayan Thrust, which defines the interface between the underthrusting India plate and the overriding Eurasia plate to the north. At the location of this earthquake, approximately 80 km to the east-northeast of the Nepalese capital of Kathmandu, the India plate is converging with Eurasia at a rate of 45 mm/yr towards the north-northeast – a fraction of which (~18 mm/yr) is driving the uplift of the Himalayan mountain range. The May 12, 2015 event is the largest aftershock to date of the M 7.8 April 25, 2015 Nepal earthquake – known as the Gorkha earthquake – which was located 150 km to the west, and which ruptured much of the decollément between these two earthquakes.”

Do we think this quake was “fracking-related”? That’s a definite maybe…

Magnitude 7.1
144km (89mi) SW of Panguna, Papua New Guinea
-7.226°S    154.551°E
depth=23.2 km (14.4 mi)

USGS: “The earthquake occurred as the result of normal faulting within the Australia plate, a few tens of kilometers to the southwest of the plate boundary where Australia begins its subduction beneath the Pacific plate at the New Britain Trench.  At the location of the earthquake, the Australia plate moves towards the east-northeast at a velocity of 103 mm/yr with respect to the Pacific plate.”
