This date in science: Landslide at Bingham Canyon Mine
April 10, 2013. On this date – a year ago today – a towering wall of dirt and rocks gave way and crashed down the side of Bingham Canyon Mine in Utah. The landslide was to be one of the largest non-volcanic landslides in the history of North America. University of Utah researchers later reported that the landslide – which moved at an average of almost 70 mph and reached estimated speeds of at least 100 mph – left a deposit so large it would cover New York’s Central Park with about 20 meters (66 feet) of debris.
Good Monday morning to all of our geo friends! We hope you had a fun and safe weekend. Here’s a read for this morning. Some of you may have questions about what caused Chile’s recent and devastating earthquake. This article tries to answer some of those questions.

Even planet Earth has its faults. Movement along those fault lines causes earthquakes, big and small, to rattle the globe every day, most recently making news this week with a powerful quake, and tsunami, striking Chile.
Here are several more articles about the UGS rockfall investigation, including our own news release with links to the published report.

Cracks in the earth and settling of the ground in areas of the Cedar Valley, both believed to be caused by over-pumping of the underground aquifer, were the focus of a special Central Iron County Water Conservancy District work meeting March 27.
Watch these interviews featuring one of our geologists, Tyler Knudsen, talk about the ground fissures and their causes.

Over-pumping of groundwater from a deep aquifer in Cedar Valley for the past three decades has caused the ground to sink and crack, inflicting damage on a would-be subdivision and putting future development at risk.

Land Subsidence and Earth Fissures in Cedar Valley, Iron County, Utah

A just-released report from the Utah Geological Survey (UGS) shows the ground has been sinking in some areas around Cedar City for decades. The comprehensive 116-page report presents the results of an investigation of land subsidence and earth fissures in Cedar Valley, Iron County, Utah, primarily due to groundwater pumping. “The sediments in the Cedar Valley that form the groundwater aquifer contain a significant amount of fine-grained silt and clay sediments. Those sediments become compacted when water is removed and the ground begins to sink,” said Tyler Knudsen, UGS project geologist.
The 1964 Great Alaska Earthquake happened 50 years ago today. It was the largest quake in U.S. history. Watch this interesting video by the U.S. Geological Survey.
Good information to know, as Utah is also prone to landslides.

The death toll from last weekend’s mudslide in Washington state rose to 16 Wednesday, with at least 176 others still unaccounted for. The rescue operation is ongoing, but prospects appear grim: No survivors have been found since Saturday, when the landslide occurred, and rain is expected to further inhibit the search. But how common are landslides like this one? Where and when do they occur? And how can you possibly avoid them?
