In contrast to simple shield and stratovolcanoes, many volcanoes change their eruptive habits both in eruption type and in the location of their vents—over time.
Highly studied systems result in eruption scenarios describing precise eruptive episodes, whereas poorly known systems can often only be characterized by generic eruption scenarios based on analogue systems.
Because both tiltmeter and weather radar data are telemetered, it is possible to capture the change in eruption styles even during the eruptive events.
In this context, the conduit inclination does not essentially alter the present argument, which states that the transition in eruption style was caused by a co-eruptive decrease of pressure within the chamber.
Because uncertainties in eruption ages and volumes increase with age of the eruptive products, it is difficult to compare the eruption rates of poorly preserved, older eruptions to recent eruptions occurring over a similar time interval.
The lack of juvenile material in eruptive products is a clear indicator that magma was not directly involved in eruption, yet a minor component of fresh glassy material may be accidental and does not necessary preclude an eruption from being phreatic in nature (e.g., Christenson et al. 2010; Pardo et al. 2014).
Mark Twain, Mark Twain in Eruption, 72 (Harper & Bros. 1940).
On Jan . 10 the observatory changed that to Code Orange, meaning "in eruption".
The show includes several dramatic paintings of Ecuador's Cotopaxi volcano in eruption and of icebergs in the Arctic.
But in recent decades the fatality rate has decreased, largely because of major improvements in eruption prediction.
From the beginning Church sought for his subjects marvels of nature such as Niagara Falls, volcanoes in eruption, and icebergs.
