(TNS) - Would your house survive a massive earthquake?

Emergency management officials say the expected Cascadia subduction zone quake could shake the Rogue Valley so hard that houses could collapse or slide off their foundations, leaving thousands homeless, injured or worse.

Even newer houses built before 1993 could see enough damage that they become uninhabitable.

“We could see sustained shaking for two to five minutes that could cause significant damage,” warned Althea Rizzo, geologic hazards program coordinator for the Oregon Office of Emergency Management. “Almost all the older homes need some kind of retrofit.”

Emergency planners will hold a seminar on how residents can better prepare their houses for the “Big One” from 6 to 8 p.m. Tuesday at Rogue Valley Council of Governments, 155 N. First St., Central Point. To register, go to https://medfordseismic.eventbrite.com.

Builders will be offered a separate seminar from 8:30 a.m. to 5 p.m. Tuesday at the same address that will provide information on the latest requirements for earthquake safety and retrofits. Registration for that seminar is at https://fema-p50-medford.eventbrite.com.
