Harm Van Avendonk

Harm Van Avendonk serves as a Research Professor at the University of Texas Institute for Geophysics (UTIG), part of The University of Texas at Austin. His research focuses on advanced geophysical imaging of Earth's tectonic plate boundaries, with extensive field experience across subduction zones, rifted margins, and collision zones worldwide.

His academic credentials include:

• PhD in Geophysics from the University of California, San Diego — Scripps Institution of Oceanography
• Bachelor of Science in Geophysics from Utrecht University, Netherlands

Van Avendonk's primary research examines crustal structure evolution in tectonic settings through seismic tomography and marine geophysics. He investigates subduction dynamics (notably New Zealand's Hikurangi margin), continental breakup processes (eastern North America), and transform boundary mechanics (Cayman Trough), analyzing how geological features influence seismic behavior and plate interactions.

His recent publications reveal concentrated investigation of the Hikurangi subduction zone using multi-year seismic experiments, mapping crustal architecture's relationship to megathrust behavior. Additional work explores continental breakup along eastern North American margins and Caribbean transform zones, demonstrating how pre-existing structures govern plate boundary evolution through innovative onshore-offshore methodologies.

Research funding derives from National Science Foundation grants and industry partnerships, enabling large-scale projects including the Seismogenesis at Hikurangi Integrated Research Experiment (SHIRE) and South Island Subduction Initiation Experiment (SISIE). These collaborative efforts involve multinational teams and generate critical datasets for understanding seismic hazards.

Based at UTIG's J.J. Pickle Research Campus facility in Austin, Texas, he operates within a multidisciplinary geophysics research environment equipped with advanced computational and laboratory resources for seismic data processing and rock property analysis.
