title: Dataset related to "Cascading Rupture of a Megathrust" submitted to Science Advance.

description: This dataset includes 16 files related to Cascading Rupture of a Megathrust, in Science Advances (Elliott et al., 2022). They are:<br>1. 2021_Chignik_fault_geometry: The file contains the fault geometry used in our model inversion for the Chignik earthquake. Every row represents a subfault and the the latitude, longitude, and depth are given for each corner of the subfault.<br>2. 2021_Chignik_FFM_slip_txt: The file lists the slip predicted by our preferred Chignik earthquake model at the center of each subfault.<br>3. 2021_Chignik_FFM_slip_grd: The slip model in GMT grd format<br>4. 2020_Sandpoint_fault_geometry: The file contains the fault geometry used in our model inversion for the Sand Point earthquake. Every row represents a subfault and the the latitude, longitude, and depth are given for each corner of the subfault.<br>5. 2020_Sandpoint_FFM_slip_txt: The file lists the slip predicted by our preferred Sand Point earthquake model at the center of each subfault.<br>6. 2020_Sandpoint_FFM_slip_grd: The slip model in GMT grd format<br>7.
