Topographic ridges express late Quaternary faulting peripheral to the New Madrid seismic zone, intraplate USA: Their tectonic implications
No full textNortheast-trending linear topographic ridges in Pliocene and Quaternary sediments adjacent to the New Madrid seismic zone (NMSZ), intraplate North America, have been long speculated to be neotectonic landforms related to reactivation of basement faults of the eastern Mississippi Valley Rift margin. Earthquake epicenters and paleoseismological studies show that eastern rift margin faults (ERMF) were active during late Quaternary south of a restraining bend in the Mississippi Valley Rift fault complex, but the ERMF zone north of the restraining bend (ERM-N) and underlying the linear ridges is seismically quiescent. A previous P-wave seismic reflection survey across the most prominent linear ridge (Rives lineament) revealed that it overlies a horst in Eocene sediment. To ascertain whether the Rives lineament could have been produced by surface faulting/folding, we collected electrical resistivity tomography (ERT) and ground penetrating radar (GPR) profiles to image the ridge\u27s shallow subsurface features. We interpret shallow folding and faulting of late Pleistocene sediment in our ERT and GPR images. Additionally, convexity of multiple topographic profiles of scarps along margins of the Rives lineament was quantified and compared to the convexity of profiles of known neotectonic scarps and of fluvial terrace riser profiles within the region. Comparison of these profiles reveals a high degree of similarity between the scarps along the Rives lineament margins and the Holocene Reelfoot thrust scarp. When combined, our results strongly suggest late Pleistocene or Holocene folding and faulting created this ridge despite its current seismic quiescence, and thus they provide useful insight for assessing the seismic hazard potential of quiescent faults in strike-slip systems in general. We conclude that the late Quaternary series of movements documented on the Reelfoot thrust was initiated to accommodate crustal shortening after transpressional fault movements on the ERM-N became inactive in late Pleistocene or early Holocene and that movement along the ERM-N may resume if the Reelfoot thrust has an interval of inactivity in the future. Our results suggest how fault interactions within a strike-slip system can change, making faults with significant amounts of seismic potential appear as though they are inactive

No full textClearing the Legal Fog: Navigating Conflicting Interpretations of the Speedy Trial Act and the Insanity Defense Reform Act for Mentally Incompetent Defendants
No full textJane, a 32-year-old individual, is facing federal criminal charges for an alleged white-collar offense that has a maximum punishment of one year in prison. On March 1, 2019, the court decides to assess Jane’s mental competency to stand trial due to concerns raised in the initial proceedings. The court, relying on the standards set forth by the United States Supreme Court,1 initiates a hearing to determine whether sufficient evidence exists to warrant a mental competency evaluation. After the competency hearing, the court concludes that there is a need for such a mental evaluation. Jane is then sent for an initial competency determination.2 After that first assessment, the court finds Jane mentally incompetent on April 1, 2019, and orders her to undergo competency restoration treatment.3 In accordance with the Insanity Defense Reform Act (“IDRA”), the court, having found Jane incompetent, commits her to the custody of the attorney general.4 The IDRA explicitly mandates a reasonable period of hospitalization, not to exceed four months, for the mental health treatment that will help Jane gain the capacity to proceed to trial.5 However, administrative delays and logistical challenges result in Jane’s waiting nine months in a state jail to receive the necessary mental health treatment. When Jane finally enters the hospital on January 1, 2020, the court starts the four-month mandatory timeline to rehabilitate Jane pursuant to the IDRA. However, the nine-month delay in Jane’s case contradicts the intent of the IDRA, which seeks to prevent the extended detention of defendants deemed incompetent.6 Jane could now be held in pretrial detention for an entire year, potentially exceeding the length of time of her sentence had she been competent and found guilty at the outset of the charges against her. Complicating the problem, the Speedy Trial Act (“STA”) requires a federal criminal defendant’s trial to commence within seventy days of the indictment.7 This substantial delay in providing Jane with a mental evaluation, together with any mental health treatment that she might need, raises questions about whether certain exceptions to the STA for defendants found mentally incompetent might delay Jane’s trial indefinitely.8 As discussed in detail in this Note, the STA excludes time from the seventy-day clock for the following reasons: delays that result from proceedings or examinations related to the defendant’s competency; delays due to the defendant’s incompetency; and delays in transporting a defendant to a hospital for examination, in which case only ten days are considered reasonable.9 The STA was designed to protect defendants’ rights to a speedy trial10 by expediting the criminal justice process and decreasing the backlog in federal courts. Jane’s extended wait for mental health treatment challenges these core principles
