Volcanic Hazards

2022
The complexity of understanding volcanic risk is partly due to the fact that it is the result of different hazards, some of which are directly linked to the eruptive activity, such as, gas, lava flows, pyroclastic flows and ash fallout, and others which are directly or indirectly induced by these hazards, such as, debris avalanches, tsunamis, mudflows ...

Volcanic hazards of the Colli Albani

2018
Although controversy exists about the age of its most recent eruption (either 36 ka or ,23 ka), Colli Albani volcano is unanimously considered to be quiescent and not exinct. During the Holocene, several lahars were generated by overflows from Albano crater lake up to the fourth century BCE, when the Romans excavated a drainage tunnel to keep the lake ...

Developing a suite of multi-hazard volcanic eruption scenarios using an interdisciplinary approach

, 2020
Understanding future eruptions and their potential consequences is an important component of volcanic disaster risk reduction. Suites of scenarios are a useful compromise between fully probabilistic and fully deterministic (single scenario) approaches ...

Auckland Volcanic Field magmatism, volcanism, and hazard: a review

, 2020
Auckland Volcanic Field (AVF) is a basaltic intraplate volcanic field in North Island, New Zealand, upon which >1.6 million people live. Seismic velocity tomography and geochemistry suggest a primary mantle source region at a depth of 70–90 km ...

Volcanic Hazards for Livestock

Outlook on Agriculture, 1996
Volcanic eruptions can cause many hazards for livestock. These include pyroclastic flows, lahars, tsunamis, lava, tephra, lightning, gas and acid rain. Experience gained during recent eruptions in New Zealand and Iceland has enlarged our understanding of the dangers so that rational reactions can be made during times of emergency.

ERUPTION HAZARD AND CHALLENGES OF VOLCANIC CRISIS MANAGEMENT ON A SMALL ISLAND: A CASE

, 2020
Ternate Island is a volcanic island formed by the product of Gamalama volcano since thousands of years ago until the present time. It covers 111.4 km2 and inhabited by more than 200,000 people.

Volcanic hazard on Etna

1985
Assessing the threat from a volcano demands as complete a knowledge as possible of its long- and short-term behaviour. As this becomes better understood, more effective land-management policies, emergency procedures and mitigation techniques can be drawn up and implemented to reduce the vulnerability of exposed communities.

Volcanic hazards and their mitigation

Geological Society, London, Engineering Geology Special Publications, 1998
Abstract Over the past century, a range of volcanic hazards, particularly pyroclastic flows and debris flows, have claimed over 60000 lives, and between 1980 and 1990 alone, have detrimentally affected the day-to-day lives of over 600 000 people.

Volcanoes and volcanic hazards

2001
In Canada, potentially active volcanoes are found only in British Columbia and the Yukon Territory, where they represent cinder cones, shield volcanoes, and stratovolcanoes. Magma composition controls how a volcano erupts. Low-viscosity magmas (basalt) erupt effusively and represent a low-level hazard.

Vesuvius: volcanic hazard and civil defense

Rendiconti Lincei, 2012
The volcano Vesuvius presents a most serious hazard in terms of human and property risk considering that there are at least 600,000 people exposed on its slopes, according to the figures given by the Italian Civil Defense Authority (DPC), on which the present Risk Zones delimitation is based. The DPC has divided the territory around Vesuvius into three
