Just added to the “Planning and Aids” section of the Diocesan Disaster Preparedness page is a Power Point program which provides a presentation on how to prepare for an earthquake. There are two versions of the presentation: the first includes narration, while the second version is silent but has a script available. Each is designed to last less than 30 minutes. They are appropriate for a time just after service or between services.
If a personal presentation is preferred, contact the Diocesan Disaster Coordinator at DDCOregon@gmail.com. There are members of the team around the state who are more than willing to come to your parish and make the presentation.
