Earthquakes near Quevedo through history

It was also the deadliest: NOAA records 40,000 deaths for it. NOAA’s list of significant earthquakes has 22 here, back to 1280. NOAA records deaths in 7 of the events here, 48,204 in all. The latest on NOAA’s list is a magnitude 7.8 on April 16, 2016 (27 km SSE of Muisne, Ecuador). NOAA’s record here begins in 1280 with an eruption (Quilotoa). It grows thinner going back: 7 of the 22 significant earthquakes NOAA lists here are from 1927 on. NOAA lists one significant eruption of one volcano within 100 km of Quevedo. The largest was Quilotoa in 1280, at 6 on the volcanic explosivity index.

• An event counts for Quevedo when it began within 100 km of its centre, or 200 km for an earthquake of magnitude 7 or more. Damage can reach further.
• USGS counts here start at magnitude 6: the catalogue’s smaller quakes thin out going back, where few instruments listened.
• NOAA lists significant events only: earthquakes that killed, did about $1 million of damage, reached magnitude 7.5 or intensity X, or raised a tsunami, and eruptions and tsunamis by like measures. Magnitudes before 1900 are its estimates from written accounts.
• Deaths are NOAA’s total for each event, wherever people died, its tsunami and fires included. A tsunami counts the dead its runup records give for this place: NOAA’s total for a tsunami includes its source quake’s.
• A tsunami from elsewhere counts where one of its runups killed or rose a metre or more.
• Counted to October 19, 2026, as is the map. The last 30 days ask USGS again.
