Humboldt Broncos bus crash. On April 6, 2018, sixteen people were killed and thirteen were injured when a northbound coach bus struck a westbound semi-trailer truck near Armley, Saskatchewan, Canada. The driver of the semi-truck had failed to yield at a flashing stop sign at the intersection of Highways 35 and 335.

The Nemaha Ridge is bounded to the east by the Humboldt fault zone (near vp 900). By far the most prominent feature on the seismic profile is the MCR. Situated between vps 1400 and 2100, the MCR is characterized by high-amplitude reflections extending to about 4 sec which represent the Keweenawan synrift package. These reflections are believed ...Surface rupture caused by normal faulting along the Lost River Fault, during the 1983 Borah Peak earthquake. In seismology, surface rupture (or ground rupture, or ground displacement) is the visible offset of the ground surface when an earthquake rupture along a fault affects the Earth's surface. Surface rupture is opposed by buried rupture, where there is no displacement at ground level.The basalt flows within the MGA itself reach a thickness of about 8 km, also. Preliminary interpretation of these latest COCORP data suggest that he Humboldt Fault zone dips about 20-30 to the east and that the Humboldt may be a reactivation of late Precambrian aged faults associated with the formation of the MGA. A belt of mostly seaward-facing normal faults borders the northern Gulf of Mexico, in westernmost Florida, southwestern Alabama, southern Mississippi, all of Louisiana and southernmost Arkansas ...

The New Madrid Seismic Zone ( / ˈmædrɪd / ), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri . The New Madrid fault system was ... western fronts of the East Humboldt Range and the northwest front of the Ruby Mountains a set of left-stepping faults from about 1 km north of Interstate 80 west of Wells, southwest to Chimney Creek, about 15 km southwest of Lamoille and 5 km north of the South Fork of the Humboldt River. Fault ID: Refers to EK5B and EK5C of dePolo (1998 #2845).Fault style and facies patterns argue against assumptions of any idealized aquifer system. Specific observations show that faults are barriers to and pathways for fluid flow in a hydrologically compartmentalized region. Regional relations further suggest that fluid flow out of the Reelfoot rift was via faults in the Precambrian basement, and ... ….

The second historical earthquake cluster is located in Pawnee and Richardson counties in southwestern Nebraska and includes eight earthquakes with equivalent moment magnitudes of 2.3 to 2.8 that occurred in a period from 1982 to 1989 over the Nemaha uplift and appear to be related to the Humboldt fault.Though the epicenter was nearly 300 miles from Council Bluffs, the tremors could be felt at least as far away as southwest Iowa, which is along the Humboldt Fault that stretches from Omaha to ...

Bedrock faults shown are the Humboldt Fault. Features shown as faults may be faults per se, zones of steep dip, or both (see Fig. 2). Note that faults strongly …Yep. Southeast Nebraska lives under a minor threat of earthquakes. The Humboldt Fault Zone is a normal fault or series of faults that extends from Nebraska southwestwardly through most of Kansas -- all the way to Oklahoma City. The Humboldt line is close enough to the Saline County that we would certainly feel the impact of a …Font Size: A 6.4 magnitude earthquake struck Northern California's Eureka area Tuesday at 2:34 a.m. (Pacific time), leaving thousands of residents without power, according to the U.S. Geological Survey.

There is only one place where a displacement can actually be seen and that is east of Humboldt. That was on the field trip.The ridge is associated with the seismically active Humboldt Fault zone. It is also associated with the Proterozoic Midcontinent Rift System, which extends into northern Kansas about fifty miles west of the Nemaha.
