Rock arches are singing and scientists are listening - Science Nation

Geologist Jeff Moore and his team from the University of Utah, supported by the National Science Foundation, are developing innovative methods to monitor the structural integrity of Utah's sandstone arches. They use seismic measurements and 3D modeling to study the arches' vibration properties, discovering each arch's unique resonant frequency. This research aids in structural health monitoring, helping land managers assess the safety of these natural landmarks. The team collects baseline data through fieldwork, providing crucial information for future safety assessments.

What is the primary goal of Jeff Moore's team in Utah?

• To create a database of all arches

• To monitor the structural integrity of geological landmarks

• To measure the height of the arches

• To discover new sandstone hills

How do the researchers use seismometers in their study?

• To measure the temperature of the arches

• To detect the color changes in the rocks

• To monitor the vibration properties of the arches

• To count the number of arches

What is the significance of each arch's resonant frequency?

• It determines the color of the arch

• It helps in identifying the age of the arch

• It measures the height of the arch

• It gives each arch a unique 'voice'

What is the purpose of creating a 3D model of the arches?

• To change the color of the arch

• To visualize the motion at every point on the arch

• To measure the temperature of the arch

• To count the number of arches

Why is structural health monitoring important for land managers?

• To increase the number of tourists

• To predict weather changes

• To change the color of the arches

• To assess the safety and stability of arches
