I have some experience with responding, as a school, to the aftermath of natural disasters. Having worked through the results of Hurricane Katrina, I offer this advice.
Ultimately, you will be remembered for how well you supported the needs of your students, families, and colleagues - NOT for how fast you caught up on your lesson plans or syllabi.
Those needs may be physical, emotional, or psychological as much as intellectual or academic.
Care for others and remember to take care of yourself.
