SHERWOOD, Ore. – No damage was reported after two small earthquakes struck near Sherwood Sunday night, but some residents found a good opportunity to double-check their disaster preparedness plans.
The epicenter of the 3.3-magnitude quake was about six miles north/northwest of Sherwood, at a depth of 12 miles. A 1.6-magnitude quake hit nearby about 10 minutes earlier.
More than 1,000 people from all over the region reported feeling the quake around 8:30 Sunday night, but no damage was reported.
A geologist from Portland State University told KGW there’s no cause for alarm after such small quakes. But he said people should review their earthquake response plans and double-check their disaster kits (see below).
One man who lives in the Sherwood area told KGW he’s been doing exactly that.
“Well, we have a large emergency aid kit that has everything in it, and we have two other first aid kits,” said Rick Reuter. “I guess we need to get more prepared in the future, like stock more water and stuff.”
