Clocking a speeding glacier reveals the fate of a disappearing lake
The metaphor of a “slippery slope” is often invoked for things that might quickly get out of control, but in glaciology these words can be applied more literally. In a warming world, we want to know how quickly ice sheets can melt and raise sea level. If melting ice lubricates the base and speeds up ice flow, losses could accelerate.
A new map of strain across the western US using GPS data
GPS/GNSS stations also record the gradual strain that accumulates along a fault until it slips again. A new study presents a fresh analysis of that strain in the western United States.
IRIS Receives NSF Award to Support Planning of Subduction Zone Observatory
The National Science Foundation (NSF) awarded nearly $500,000 to IRIS to conduct activities focused on Subduction Zone in Four Dimensions (SZ4D). SZ4D is an initiative in the research community to study subduction zones – the places where tectonic plates converge and collide – through both space and time, with a focus on the fundamental processes underlying geologic hazards such as great earthquakes, tsunamis, landslides, and volcanic eruptions. UNAVCO is a subawardee on this award to IRIS.
New video: Supporting rockfall hazard studies in Zion
Zion Canyon’s beauty and scale wouldn’t be possible without countless rockfall events that hastened its carving. But now that human infrastructure exists in the park—carrying millions of visitors each year—rockfall presents a significant risk that has to be managed. UNAVCO recently supported a project assessing that risk in two locations in the park.
New user identity management system for data access
There are lots of exciting changes on the way as a part of UNAVCO’s coming merger with IRIS to form EarthScope Consortium, including the development of a new common cloud platform (CCP) for data services. This complex project is well underway and will be rolling out in stages, with the goal of a transparent and … Continued
Alumni of internship programs awarded NSF fellowships
The National Science Foundation recently announced the 2022 recipients of its Graduate Research Fellowship Research Program awards—and the list included two alumni of UNAVCO internship programs!
Borehole project in Italy will help answer questions about enigmatic faults
Italy has experienced several deadly earthquakes in recent years. They all occurred within a complicated fault system that challenges our models for fault behavior. An array of instruments has been deployed across the region to help geoscientists around the world study these faults. And with support from UNAVCO, the latest addition to that array is a number of borehole strainmeters.
Study led by UNAVCO staff tests an alternative way to measure earthquakes
There’s another way to approach this problem, and that’s to directly measure the station’s velocity as it moves during an earthquake—which has the advantage of working without relying on external correction information.
2022 Technical Short Course Offerings
Are you looking to refine your geodesy knowledge and gain mapping skills? UNAVCO hosts technical short courses each summer that provide training on geodetic data processing techniques and tools.
