7 sie 2024 · Tungurahua II itself collapsed about 3000 years ago and produced a large debris-avalanche deposit and a horseshoe-shaped caldera open to the west, inside which the modern glacier-capped stratovolcano (Tungurahua III) was constructed. Historical eruptions have all originated from the summit crater.
10 sie 2020 · Here we describe an episode of over 900 LP earthquakes recorded in November 2015 at Tungurahua Volcano, Ecuador, that we believe are associated with a failed explosion. Rates of LP drumbeats accelerated for 10 hr, consistent with an inverse Omori's law.
1 paź 2017 · The unrest episode at Tungurahua in April 2015 provides valuable new observations of highly-periodic LP seismic activity, and offers important insights into possible LP earthquake source mechanisms and conduit processes.
27 lis 2011 · Tungurahua II collapsed about 3,000 years ago and produced a large debris-avalanche deposit to the west. The modern glacier-capped stratovolcano (Tungurahua III) was constructed within the landslide scarp.
28 sie 2020 · Here we describe an episode of over 900 LP earthquakes recorded in November 2015 at Tungurahua Volcano, Ecuador, that we believe are associated with a failed explosion. Rates of LP drumbeats...
30 gru 2022 · The most recent eruptive period of Tungurahua volcano lasted 17 yr (1999–2016), generating strong eruptive phases with the release of large amounts of seismic and acoustic energies. We have selected 10 large eruptions and located their seismic sources.
An episode of accelerating and decelerating long-period (LP) drumbeat earthquakes is identified at Tungurahua volcano, Ecuador. Bayesian gamma point process analysis constrains mirrored sequences of Omori law accelerating and decelerating seismicity.
