The AVO reported an explosion at Cleveland Volcano, located in the Aleutian arc, detected, on 04.16.2016 at 10:58 local / UTC 6:58 p.m., by seismic and infrasonic data (pressure in the air). Cloud cover did not get satellite images.

The level of aviation alert went from orange to yellow.

After the strong earthquakes strucking the island of Kyushu in Japan and the Vanuatu archipelago, it is Ecuador that was hit on April 16 at 11:58 p.m. UTC by a 7.8 magnitude earthquake at a depth of 19.2 km ., followed by a fifty replicas. (USGS).

At least 41 killed and hundreds wounded; the damage is huge in coastal areas.

The April 16, 2016 M 7.8 earthquake, offshore of the west coast of northern Ecuador, occurred as the result of shallow thrust faulting on or near the plate boundary between the Nazca and Pacific plates. At the location of the earthquake, the Nazca plate subducts eastward beneath the South America plate at a velocity of 61 mm/yr. The location and mechanism of the earthquake are consistent with slip on the primary plate boundary interface, or megathrust, between these two major plates. Subduction along the Ecuador Trench to the west of Ecuador, and the Peru-Chile Trench further south, has led to uplift of the Andes mountain range and has produced some of the largest earthquakes in the world, including the largest earthquake on record, the 1960 M 9.5 earthquake in southern Chile. Ecuador has a history of large subduction zone related earthquakes. Seven magnitude 7 or greater earthquakes have occurred within 250 km of this event since 1900.
