Each year, Simpson Strong-Tie teams up with the West Coast’s top earthquake scientists and preparedness experts to take questions from Redditors about earthquakes and tsunamis. The Reddit AMA is part of the Great ShakeOut, the world’s largest earthquake drill, where 55 million people drop, cover and hold on. The next Great ShakeOut is scheduled to take place at 10:17 a.m. on October 15, 2020.
