Cascadia Earthquake Presentation

Thursday, April 9, 2015 - 6:00pm to 8:00pm

While most people know that California gets frequent earthquakes, they may not know that Oregon is at risk from very large earthquakes. These earthquakes on the Cascadia Subduction Zone can be over 9.0 magnitude and have a region-wide impact. The Cascadia Subduction Zone represents the single largest hazard to the people and built environment of Oregon.

On April 9, Dr. Althea Rizzo, the Geological Hazard Program Coordinator at the Oregon Office of Emergency Management, will cover the latest understanding on the natural hazard and its expected impact on Oregon. Learning how to prepare and protect your family, home and business starts by attending this presentation. Being able to recover quickly from a catastrophic event is a choice that needs to be made before the event.

This is a free presentation but because space is limited, pre-registration is required. Contact Bonnie Hirshberger at or 503-675-3992 to register.

This presentation will also be televised live online at or on Tualatin Valley Community Television (TVCTV) Channel 30. In addition, it will be available on YouTube the following day at
