2 janv. 2024 · The EQ (earthquakes) cluster marks the intense seismic activity prior to the eruption. Samples in this cluster represent time windows of seismic signal when transient earthquakes are the most...
21 avr. 2020 · The persistence of the summer cooling following our proposed eruption cluster between 1108 and 1110 CE is also heterogeneous in spatial terms.

12 sept. 2023 · These eruptions occurred along two linear vent zones within Yellowstone caldera that appear to be extensions of major extracaldera normal faults. Eruptions took place in five brief clusters with group mean ages of 160.3±1.0 ka (2σ), 149.8±4.0 ka, 111.4±0.9 ka, 104.1±0.8 ka, and 70.8±0.7 ka.
Identifying seismic signature of different eruption phases. The 2021 Geldingadalir eruption features different volcanic phases such as pre-eruptive activities, continuous lava extrusion, and ...
22 mars 2021 · This study reveals different processes that influence earthquakes during a volcanic eruption using an automated clustering method. 1 Introduction. On April 30, 2018, a dike intrusion in the East Rift Zone (ERZ) marked the beginning of intense volcanic and seismic activity at Kilauea volcano, Hawaii (Anderson et al., 2019; Neal et al., 2019 ).

1 avr. 2023 · During the clusters, large eruption frequencies averaged 1 every 20–45 kyrs. The eruption clusters were separated by hiatuses of ∼240–260 kyr, recorded by soils and unconformities, and may reflect marked changes in geographic dispersals following giant landslide breaches in Las Cañadas caldera wall. Two concurrent evolutionary ...
