Large earthquakes in stable continental regions remain puzzling as; unlike at plate boundaries, they do not result from the local buildup of strain driven by plate tectonics. The 2017 Mw6.5, Bostwana normal faulting earthquake occurred in a region devoid from recent tectonic activity and where present-day deformation is negligible. The depth of the event (29 ± 4 km), in a felsic lower crust where ductile deformation is expected, likely requires a transient pulse of fluids from a deep source to…

Rupture process of the April 2017 Mw 6.5 Botswana Earthquake: deepest earthquake observed in continental Africa
On April 3, 2017, an earthquake of magnitude Mw 6.5 ruptured in Botswana in a region where there was no significant recent tectonic activity and where present-day deformation is believed to be
Surface deformation relating to the 2018 Lake Muir earthquake sequence, southwest Western Australia: new insight into stable continental region earthquakes
Abstract. A shallow Mw  5.3 earthquake near Lake Muir in the stable continental region (SCR) crust of southwest Western Australia on the 16 September 2018 was followed on the 8 November by a proximal
The Preseismic and Postseismic Phases of the 700‐km Deep M7.9 Bonin Islands Earthquake, Japan
The 30 May 2015 Mw 7.9 Bonin Islands earthquake, Japan, is one of the largest deep-focus earthquakes ever recorded. Its occurrence, close to 700-km depth, in an area without any known historical
On the Origin of Orphan Tremors and Intraplate Seismicity in Western Africa
On September 5–7, 2018, a series of tremors were reported in Nigeria’s capital city, Abuja. These events followed a growing list of tremors felt in the stable intraplate region, where earthquakes are
A Parametric Analysis of Fault Reactivation in the New Madrid Seismic Zone: The Role of Pore Fluid Overpressure
Earthquakes in Stable Continental Regions (SCR), where localized present‐day tectonic loading is negligible, remain difficult to explain. The New Madrid Seismic Zone (NMSZ) is a type‐locale for such


Evidence for the release of long‐term tectonic strain stored in continental interiors through intraplate earthquakes
The occurrence of large earthquakes in stable continental interiors challenges the applicability of the classical steady-state ‘seismic cycle’ model to such regions. Here, we shed new light onto this
Earthquake swarms in non‐volcanic regions: What fluids have to say
The detailed processes generating earthquake swarms are complex and not fully understood. Most earthquake swarms occur in volcanic regions and mid-ocean rifts. Here, we report new 3 He/ 4 He data of
Did Anthropogenic Activities Trigger the 3 April 2017 Mw 6.5 Botswana Earthquake?
The retrieved fault geometry and mechanism are incompatible with the hypothetical stress perturbation caused by the anthropogenic activities performed in the area, and the 3 April 2017 Botswana earthquake can be classified as a natural intraplate earthquake.
A new paradigm for large earthquakes in stable continental plate interiors
Large earthquakes within stable continental regions (SCR) show that significant amounts of elastic strain can be released on geological structures far from plate boundary faults, where the vast
Seismic and Aseismic slip: The Japanese Subduction Zone
Transient aseismic slip events (that do not emit elastic waves) were first discovered on the San Andreas fault in central California in 1960 (Steinbrugge et al., 1960; Tocher, 1960) and were later
Intense foreshocks and a slow slip event preceded the 2014 Iquique Mw 8.1 earthquake
To understand the seismicity preceding this event, the location and mechanisms of the foreshocks and computed Global Positioning System time series at stations located on shore were studied and model as a slow slip event situated in the same area where the mainshock occurred.
Multiple slow‐slip events during a foreshock sequence of the 2014 Iquique, Chile Mw 8.1 earthquake
To obtain a precise record of the foreshock sequence before the 2014 Iquique, Chile Mw 8.1 earthquake, we applied a matched filter technique to continuous seismograms recorded near the source region.
Indications for a successively triggered rupture growth underlying the 2000 earthquake swarm in Vogtland/NW Bohemia
[1] The characteristics of earthquake swarms can neither be described by simple laws nor are the underlying mechanisms presently understood. Swarm activity is often assumed to be caused by an
Propagation of Slow Slip Leading Up to the 2011 Mw 9.0 Tohoku-Oki Earthquake
The time history of quasi-static slip along the plate interface, based on small repeating earthquakes that were part of the migrating seismicity, suggests that two sequences involved slow-slip transients propagating toward the initial rupture point.
