Area of ​​the Long Point FaultThe Long Point Fault is located in Harris County, covering 83,450 square miles located in Houston, Teaxas City Limits. The research specifies that there are three sections of the Long Point Fault that appear to be active; some sections of the Long Point Fault have averaged more than 2 cm per year of vertical displacement over the past 20 years. Tests of defects conclude that it is a natural defect. The reason for the activity is not caused by humans, although human activities do not help to solve the problem, but clearly humans are not the initial cause, biological activity may in fact be an additional cause of its movement . A brief description of the fault type and its relationship to the strata and faults beneath the Houston area, which lie at depths between 1,000 and 4,000 m. They have been well defined through the study of well logs and seismic lines. Studies have led to the hypothesis that some of these subsurface faults penetrate younger sediments at shallower depths and contain faults that set the present land surface to produce recognizable scarps. (Gabrysh) The geologic history of the Houston area includes surface water found in several types of lakes, rivers, and a large system of bayous and man-made canals that all share the stormwater runoff management system. In Harris County, 25%-30% of the land lies within a 100-year floodplain. Harris elevation range 0'-310', so currently the Earth's surface and uppermost sediments in the Houston area are geologically very young strata, and research isolates that its age is measured in tens of thousands, not millions, of years . Distinctly this knowledge concludes that it is flawed by a natural process, before significant fluid extraction has...... middle of paper ......ler CW "Lineations and fauts in the Texas Coastal Zone."
