On Feb. 28, 2005, an undersea hydrophone network began detecting the most intense swarm of earthquakes to occur in the last three years along the Juan de Fuca Ridge, about 320 kilometers (200 miles) off the Pacific Northwest coast. Each red dot represents an earthquake epicenter. Within five and a half days, the hydrophones had detected 3,742 earthquakes.
