Article
We produced a globally distributed catalog of earthquakes and nuclear explosions with calibrated hypocenters, referred to as the Global Catalog of Calibrated Earthquake Locations (GCCEL). This dataset currently contains 18,782 events in 289 clusters with >3.2 million arrival times observed at 19,258 stations. The term “calibrated” refers to the pro...
Article
On June 14, 2020, Mw 5.9 Kaynarpınar earthquake occurred in the easternmost part of the North Anatolian Fault Zone, along the Yedisu Seismic Gap near the Karlıova Triple Junction. Following the event, various agencies reported different epicenter locations. This issue and the complex fault pattern around the triple junction caused uncertainties abo...
Article
Seismic stations and seismic arrays suffer from unwanted seismic noise as a result of inevitable population growth and development. This encroachment of noise degrades stations’ performance. Moving stations to a quieter location breaks the continuity of historical records and can be logistically complicated. This is especially true for seismic arra...
Article
We investigate active tectonics in southwestern Turkey along the trend between Fethiye, near the eastern end of the Hellenic subduction zone, and Burdur, on the Anatolian plateau. Previously, regional GNSS velocities have been used to propose either (1) a NE-trending zone of strike-slip faulting coined the Fethiye-Burdur Fault Zone, or (2) a mix of...

28 We produced a globally distributed catalog of earthquakes and nuclear explosions with calibrated 29 hypocenters, referred to as the Global Catalog of Calibrated Earthquake Locations or GCCEL. 30 This dataset currently contains 15,627 events with more than 2.6M arrival times observed at 31 17,826 stations. The term "calibrated" refers to the prop...

Between 2014 and 2017, almost 200 new seismic stations were installed in Alaska and northwestern Canada as part of the EarthScope USArray Transportable Array. These stations currently provide an unprecedented capability for the detection and location of seismic events in regions with otherwise relatively sparse station coverage. Two interesting ear...

Full-text available
Earthquake location is a well-defined inverse problem to which the mathematical fundamentals of existing methodologies were established nearly a century ago. However, in quantitative seismology, achieving accurate, bias-free earthquake locations still remains to be the one of most important and challenging tasks. In this article, we give an overvie...

Plain Language Summary We investigate the 2020 Mw 6.8 Elazığ (Turkey) earthquake, the largest along the East Anatolian Fault (EAF) in over a century. Anatolian faults are emblematic within the earthquake science community, but most attention has focused on the North Anatolian fault which ruptured repeatedly during the twentieth century, and relativ...
Article
Full-text available
The largest earthquakes recorded in northern Alaska ( Mw 6.4 and Mw 6.0) occurred ∼6 hr apart on 12 August 2018, in the northeastern Brooks Range. The earthquakes were captured by Sentinel‐1 interferometric synthetic aperture radar (InSAR) satellites and Earthscope Transportable Array seismic data, giving insight into the little‐known active tecton...
Article
Full-text available
We use calibrated earthquake relocations to reassess the distribution and kinematics of faulting in the Zagros range, southwestern Iran. This is among the most seismically active fold‐and‐thrust belts globally, but knowledge of its active faulting is hampered by large errors in reported epicenters and controversy over earthquake depths. Mapped cose...
Article
A triplet of M w ∼6 earthquakes on 2017 December 1-12 occurred ∼50 km north of Kerman, Iran, in an area of mountainous topography where several major right-lateral strike-slip fault systems - the Gowk, Nayband, Lakar Kuh and Kuh Banan faults - converge. Here we assess their source parameters and surficial expression using regional and teleseismic w...

The 12 November 2017 Mw 7.3 Ezgeleh–Sarpolzahab earthquake is the largest instrumentally recorded earthquake in the Zagros Simply Folded Belt by a factor of ∼10 in seismic moment. Exploiting local, regional and teleseismic data and InSAR imagery, we characterize the rupture, its aftershock sequence, background seismicity, and regional tectonics. Th...
Article
The 20 July 2017 Bodrum–Kos earthquake (Mw 6.6) is the largest instrumentally-recorded earthquake in the Gökova graben, one of the primary physiographic features of SW Turkey. Using seismology and satellite geodesy, we investigate its source characteristics, aftershock distribution, relationship with earlier instrumental seismicity, and association...
Article
Western Turkey has a long history of large earthquakes, but the responsible faults are poorly characterized. Here we reassess the past half century of instrumental earthquakes in the Simav-Gediz region, starting with the 19 May 2011 Simav earthquake (Mw 5.9), which we image using interferometric synthetic aperture radar and regional and teleseismic...
Article
The South Tharsis Ridge Belt (STRB) is located along the northeastern edge of Terra Sirenum and partially surrounds the southwestern part of Tharsis in an arc. It consists of 29 large ridges separated by distances 130 to 260km, with average relief of 1.5km above the surrounding plains. Because the STRB is among the oldest tectonic features associat...
Article
We present source models for the August 2014 Murmuri (Dehloran) earthquake sequence in the Zagros Mountains of Iran. An Mw6.2 mainshock was followed by an aftershock sequence containing five events of Mw ≥ 5.4. Models of P and SH waveforms show that all events had dominantly thrust-faulting mechanisms, and had centroid depths that place them within...

We analysed locations and focal mechanisms of events with magnitude ≥3, which are recorded by 39 broad-band seismic stations deployed during the North Anatolian Passive Seismic Experiment (2005-2008) around central segment of the North Anatolian Fault (NAF). Using P- and S-arrival times, earthquakes are relocated and a new 1-D seismic velocity mode...

Origin of ridges in the South Tharsis ridge belt is evaluated, using evidence from topographic profiles,deformed craters,tectonic modeling, and crustal thickness.Though no one model explains all aspects of ridges,results support an extensional origin.
Article
The North Anatolian Fault (NAF) is one of the world's largest active continental strike-slip faults, and forms the northern margin of the Anatolian plate. Although its geologic and geomorphologic features are well defined, crustal deformation and associated seismicity around central segment of the NAF is relatively less-known. In this study, we ana...
