The 1987 Ecuador earthquakes occurred over a six-hour period on March 6. The sequence of shocks measured 6.7, 7.1, and 6.0 on the moment magnitude scale. The mainshock had a maximum Mercalli intensity of IX (Violent). The earthquakes were centered in Napo Province in northeast Ecuador; the epicenters were on the eastern slopes of the Andes, about 75 km ENE of Quito and 25 km north of Reventador Volcano. The earthquakes caused about 1,000 deaths. Four-thousand were missing and an estimated US$1 billion in damage was caused.
