The PI will participate in the German-funded PAGANINI project and join the initial geophysics leg to collect OBS and OBH data from the Middle America Trench. The UTIG efforts will be focused on Profiles 5 and 6 (outboard of Nicoya Peninsula, and onshore/offshore profile from Sandino Forearc to Costa Rica, respectively). The PI will have the primary responsibility for analysis and interpretation of these two profiles (out of a total of eight profiles to be collected). The objective is to study the seismogenic zone through crustal velocity and crustal mass flux modeling. The work also bears on future ODP drilling in the area for the seismogenic zone experiment.

PI将参与德国资助的PAGANINI项目，并加入最初的地球物理学分支，从中美洲海沟收集OBS和OBH数据。 UTIG的工作重点将放在剖面5和剖面6（分别为尼科亚半岛外侧和桑迪诺前弧至哥斯达黎加的陆上/海上剖面）。 PI将主要负责分析和解释这两个特征（共收集8个特征）。 目的是通过地壳速度和地壳质量通量模拟研究孕震区。 这项工作也关系到未来ODP钻井在该地区的孕震区实验。
