A 5.6-magnitude earthquake is strong enough to cause light to moderate structural damage, particularly to older or poorly constructed buildings. Shaking at this intensity can topple furniture, crack walls, and break windows, and is typically felt across a wide area.
“No tsunami warning, advisory, watch, or threat,” the US Tsunami Warning System wrote on its website.
