Cuicocha volcano news & activity updates:
Thu, 4 Oct 2018, 20:33
The geophysical institute of Ecuador reports that seismicity at Cuicocha caldera has increased. 60 earthquakes, up to a magnitude of 2.5 have been recorded in the last two days. All are of the volcano-tectonic (VT) type, meaning they are caused by rocks breaking. The significance of this activity remains to be seen, but as it stands there is no concern; the volcano last erupted about 1,370 years ago; much more intense activity would be expected before any eruption.
