The 2013 Bingham Canyon landslide, moment by moment

In spring 2013, observation systems at Utah’s Bingham Canyon copper mine detected ground movement in a hillslope surrounding the mine’s open pit. Out of caution, mine managers evacuated personnel and shut down production, waiting for the inevitable.

 

On April 10, at 9:30 p.m. and again at 11:05 p.m., the slope gave way and thundered down into the pit, filling in part of what had been the largest man-made excavation in the world. Later analysis estimated that the landslide was at the time the largest non-volcanic slide in recorded North American history. Now, University of Utah geoscientists have revisited the slide with a combined analysis of aerial photos, computer modeling, and seismic data to pick apart the details. The total volume of rock that fell during the slide was 52 million cubic meters, they report, enough to cover Central Park with 50 feet of rock and dirt. The slide occurred in two main phases, but researchers used infrasound recordings and seismic data to discover 11 additional landslides that occurred between the two main events. Modeling and further seismic analysis revealed the average speeds at which the hillsides fell: 81 mph for the first main slide and 92 mph for the second, with peak speeds well over 150 mph.

 

The study shows how the team’s methods can be used to remotely characterize a landslide, and the details they elicited from the data may be useful in planning for and modeling future landslide events.

The results are published in Journal of Geophysical Research-Earth Surface.

hao-1-img_1156_srgb-copy

Dr. Hao Zhang recently joined the University of Utah Seismograph Stations (UUSS) as a Postdoctoral Research Associate in Earthquake Seismology. He comes to Utah from the Department of Earth and Planetary Sciences at Northwestern University where he was a postdoctoral researcher.

Dr. Zhang received both his B.S. and Ph.D. in Geophysics from Peking University. His doctoral dissertation was titled, “Imaging the Rupture Processes of Earthquakes Using the Relative Backprojection Method”.

Some of his research accomplishments include:

  • Rapidly resolving rupture processes of the 2015 Mw 7.8 Nepal earthquake and its Mw 7.3 aftershock using a multi-array back-projection method.
  • Relocating a scattering source in the Lake Superior region.
  • Detecting microseismic events and performing cluster analyses in the south Chicago suburban region.
  • Studying the crustal structure in the Middle Continent Rift System using P-wave receiver functions.
  • Investigating the topography of the 410 km discontinuity in the Java subduction zone using 3-D pre-stacked Kirchhoff migration.

Dr. Zhang will work with UUSS faculty, staff, and students on problems of earthquake detection, location, and characterization in the Intermountain West.

Kristine Pankow (Associate Director, UUSS) says, “We are excited to have Hao join our research team here at UUSS. He brings valuable skills that will help us move our research forward.”

New Report Forecasts the High Likelihood of Damaging Earthquakes During the Lifetime of Many Utah Residents

A Press Release from the authors of a comprehensive study of earthquake probabilities for the Wasatch Front Region in Utah, Idaho, and Wyoming.

Salt Lake City (April 18, 2016) In the first comprehensive study of its kind for Utah, Earthquake Probabilities for the Wasatch Front Region in Utah, Idaho, and Wyoming forecasts the chances for damaging earthquakes in the Wasatch Front region. In the next 50 years there is a 43 percent chance, or nearly 1-out-of-2 odds, of at least one large earthquake of magnitude 6.75 or greater. For a moderate quake of magnitude 5 or greater the probability is 93 percent, or greater than 9-out-of-10 odds.

“Considering that the average age of Utah’s citizens is the youngest in the nation at about 29 years, there is a realistic chance that many current residents will experience a large earthquake in their lifetime,” says Ivan Wong, Principal Seismologist at Lettis Consultants International and lead author of the report.

The soon-to-be-released report is a collaboration of 14 scientists from academia, federal and state agencies, and private industry. The results underscore the importance of being prepared for damaging earthquakes in Utah.

Seismograph Stations Reaches 50-year Mark

50th InvitationThe centennial of the installation of the first seismographs on the University of Utah campus by Dr. James E. Talmage was celebrated on June 29, 2007. April 2016 brings another milestone―the 50-year anniversary of the founding of the University of Utah Seismograph Stations (UUSS).

On April 11, 1966, the University of Utah Board of Regents recognized the Seismograph Stations as an organizational entity in formally appointing Dr. Kenneth L. Cook as its first director, a position he held until 1976.

The term “University of Utah Seismograph Stations” originally referred to a small group of seismographic installations with onsite photographic recording. In 1962 the University operated stations on campus, in Price, and at Dugway; data from a fourth station owned by Utah State University in Logan were incorporated. Attendants at the remote stations routinely mailed paper seismograms to the University for analysis and interpretation. Data added from three other stations in Utah during the mid-to-late 1960s enabled a skeletal statewide seismographic network to emerge.

During Governor Calvin L. Rampton’s term of office (1965–1977), Dr. Cook served on two advisory bodies to the governor. Persuaded that seismic monitoring was vital to the welfare and safety of the people of Utah, Governor Rampton initiated state funding to the University of Utah Seismograph Stations in 1971 and helped establish this funding as a line-item appropriation from the Utah State Legislature beginning in 1972.

A number of significant changes over the past 50 years have contributed to an evolution in the character of UUSS. These include changes both in technology and in motivations for seismic monitoring. Regional earthquake monitoring has long been prompted by damaging earthquakes. In the 1960s, the monitoring of underground nuclear tests became important. In the 1970s, there was a growing interest in earthquake research and in earthquake prediction. The 1980s brought the added need to serve emergency management and earthquake engineering. Since 2000, UUSS has been involved in multipurpose seismic monitoring as part of an Advanced National Seismic System.

In 1974, a major transformation of the University of Utah’s seismograph network began under the direction of Drs. K. L. Cook, R. B. Smith, and S. H. Ward (director, 1976–1980). Onsite-recording installations were superseded by a regional telemetered seismic network involving radio, microwave, and telephone telemetry. In early 1974, there were two telemetered stations in the UUSS network. By the end of 1975, an additional 25 telemetered stations were added to form a regional network with continuous centralized recording on the University campus that covered much of the Wasatch Front area (recording was on multi-channel film recorders). Geographic coverage expanded to other parts of the Utah region with a total of nearly 60 stations operating by the end of the 1970s.

Under Dr. Robert B. Smith (director, 1980–1985), digital seismic recording of the UUSS regional seismic network began in January 1981. Also, a local seismic network in the Yellowstone National Park region, originally installed by the U.S. Geological Survey, was integrated into UUSS operations and research.

Multi-year efforts by Dr. Walter J. Arabasz (director, 1985–2010) to foster a strong state earthquake program and to help achieve congressional authorization of an Advanced National Seismic System (ANSS) resulted in access to state and federal funds for improved seismic monitoring and enabled significant modernization and statewide expansion of the UUSS regional seismic network. In 2000, in advance of the 2002 Salt Lake City Winter Olympics, UUSS began implementing a real-time earthquake information system together with the integration of urban strong-motion monitoring into the UUSS regional seismic network. Further growth followed major increases in state funding in 2007 and in ANSS funding in 2009. In 2009, UUSS moved its network operations into seismically-hardened, state-of the-art facilities in the Frederick Albert Sutton building on the university campus, and the Rio Tinto Earthquake Information Center was inaugurated.

Since, 2010, Dr. Keith D. Koper (director, 2010-present) has overseen the implementation of a state-of-the-art ANSS Quake Monitoring System to detect and locate seismicity in the Utah and Yellowstone regions. As of April 2016, UUSS maintains and operates 237 seismic stations (ANSS network codes: UU [194 stations], WY [28 stations], and NP [15 stations]). As a member of the Utah Earthquake Program, UUSS collaborates with state agencies and professional partners to better understand Utah’s earthquake threat and to advise policy makers (both state and federal) regarding seismic-related safety issues.

As UUSS enters its 51st year of operations, it continues to pursue a four-fold mission: 1) Earthquake recording and monitoring in the Utah and Yellowstone regions as a member of the ANSS, 2) Generation of timely earthquake-related data products for research and seismic safety planning, 3) Academic research and teaching as part of a larger seismology group within the Department of Geology and Geophysics, and 4) Education and outreach to increase awareness and understanding of earthquakes and the earthquake threat in Utah and Yellowstone.
