The recent magnitude 6.0 earthquake that jolted Napa Valley has caused extensive damage to wineries and properties and has particularly highlighted the need for an early warning system in the state of California. Reportedly, even a few seconds warning before the occurrence of a seismic event could have a significant impact on lowering the devasting consequences of a temblor.
The Minnesota Vikings announced last week that they plan to add $19.7 million to their contribution towards building a new stadium for the NFL team. Vikings Vice President Lester Bagley made the announcement at the Minnesota Sports Facilities Authority (MSFA) meeting in Minneapolis alongside John Wood with Mortenson Construction and MSFA chair Michele Kelm-Helgen. The additional funding means the Minnesota Vikings have now contributed $526 million towards the new facility which has a total price tag of over a billion dollars. Lester Bagley announced that the extra funding was to counter the rising price of steel and ensure all of the items from the original plan were built on time. There is roughly 7,000 tons of steel in the stadium’s external shell. The steel was budgeted at $4,800 per ton but is now costing closer to $6,000 per ton.
Rains, exceeding all historical records since 1976, have caused massive landslides last week in the outskirts of Hiroshima, urging the evacuation of residential areas and rising the death toll to 50 people so far, with many more reported missing. About 600 emergency personnel were already in the area, however forecasts of more rain made rescue efforts even more difficult. The video below shows the extent of the damage.
An enormous crack emerged between the Costa de Hermosillo and the coast, in Sonora, northwest Mexico, baffling the locals and initiating geological investigations to explain what caused the fissure. A drone, which flew over the area, captured the spectacular fissure measuring eight meters in depth and approximately 1 kilometer in length in a video which can be viewed below!
A magnitude 6.0 earthquake struck the Napa Valley region on Sunday and injured at least 172 people. The earthquake left many cracked roads, damaged buildings, and broken wine bottles. The earthquake was the largest to hit the California Bay Area since the 1989 Loma Prieta earthquake. Safety inspectors have been working around the clock to check on the health of the area’s infrastructure.
For more than 20 years, the Pile Dynamic instrument, Pile Integrity Tester (PIT), has offered an ideal means of ensuring that piles and/or shafts are free of cracks and voids before construction of the superstructure. PIT may be used on most deep foundation systems, including concrete and wood foundations, as well as on piles supporting bridges or towers, also assessing their length. It performs wave equation-based non-destructive foundation investigations known as Low Strain Impact Integrity Tests or Low Strain Dynamic Tests.
