Invited by State Key Laboratory of Geodesy and Earth`s Dynamics (SKLGED), assistant professor Brandon Michael Schmandt from the University of New Mexico visited Institute of Geodesy and Geophysics (IGG) and gave two academic reports “Investigating Mount St. Helens seismicity and volcanic arc structure with a dense geophone array” and “Seismically imaging the mantle transition zone beneath EarthScope’s USArray” on July 27.
The first report introduced the geological background of Mount St. Helens and earthquake networks around the volcano. Precise positioning results of earthquake events around the volcano were gived by using seismic wave signal recorded by earthquake networks, whichshowed that there are narrow magma paths beneath the volcano.
The second report introduced seismically imaging results of the mantle transition zone beneath United States mainland by using teleseismic signals recorded by USArray. And Schmandt pointed out that inappropriate velocity model may generate fictitious undulation of the mantle transition zone.
Brandon Michael Schmandt published more than 30 articles in internationally recognised journals, such as Science、Nature、GRL, etc. In addition, He acquired Keiiti Aki Young Scientist Award in 2013.
