However, many type-volcanoes exhibit a range of eruption styles over time e. From the perspective of risk and impact, it is useful to distinguish between near-source and distal hazards. Near-source hazards are far more unpredictable than distal hazards. Near-source hazards include those that are airborne, such as tephra fallout, volcanic gases, and volcanic projectiles, and those that are transported laterally on or near the ground surface, such as pyroclastic density currents, lava flows, and lahars.

Pyroclastic density currents are hot volcanic flows containing mixtures of gas and micron- to meter-sized volcanic particles. They can travel at velocities exceeding km per hour.

The heat combined with the high density of material within these flows obliterates objects in their path, making them the most destructive of volcanic hazards.

Lava flows also destroy everything in their path, but usually move slowly enough to allow people to get out of the way. Lahars are mixtures of volcanic debris, sediment, and water that can travel many tens of kilometers along valleys and river channels. They may be triggered during an eruption by interaction between volcanic prod- Page 21 Share Cite Suggested Citation:"1 Introduction.

While this classification of magnitude does not capture the diversity of eruption features it is a starting point for characterization and comparison of the volumes of magma erupted in explosive eruptions. TABLE 1. Near-source hazards are acute events that operate on very short time frames, on and close to the volcano, with limited warning time.

Distal hazards include flooding and sedimentation over extended areas, airborne ash, and fallout of tephra downwind of the volcano. Lahars can be more devastating than the eruption itself.

Ballistic blocks are large projectiles that typically fall within 1—5 km from vents. The largest eruptions create distal hazards. Explosive eruptions produce plumes that are capable of dispersing ash hundreds to thousands of kilometers from the volcano.

The thickness of ash deposited depends on the intensity and duration of the eruption and the wind direction. Airborne ash and ash fall are the most severe distal hazards and are likely to affect many more people than near-source hazards.

They cause respiratory problems and roof collapse, and also affect transport networks and infrastructure needed to support emergency response. Do you know where do my friends live?

II and III. Volcanic ash can collapse weak structures, cause power outages, and is a challenge to shovel away post-eruption. Can we predict volcanic eruptions? Volcanoes give some warning of pending eruption, making it vital for scientists to closely monitor any volcanoes near large population centers.

Warning signs include small earthquakes, swelling or bulging of the volcano's sides, and increased emission of gasses from its vents. None of those signs necessarily mean an eruption is imminent, but they can help scientists evaluate the state of the volcano when magma is building. However, it's impossible to say exactly when, or even if, any given volcano will erupt. Volcanoes don't run on a timetable like a train.

Video courtesy Warren Fintz What is the largest eruption in history? The deadliest eruption in recorded history was the explosion of Mount Tabora in Indonesia. The blast was one of the most powerful ever documented and created a caldera —essentially a crater—4 miles across and more than 3, feet deep.

A superheated plume of hot ash and gas shot 28 miles into the sky, producing numerous pyroclastic flows when it collapsed. The eruption and its immediate dangers killed around 10, people. But that wasn't its only impact.

The volcanic ash and gas injected into the atmosphere obscured the sun and increased the reflectivity of Earth, cooling its surface and causing what's known as the year without a summer. Starvation and disease during this time killed some 82, more people, and the gloomy conditions are often credited as the inspiration for gothic horror tales, such as Mary Shelley's Frankenstein.

Although there have been several big eruptions in recorded history, volcanic eruptions today are no more frequent than there were a decade or even a century ago. At least a dozen volcanoes erupt on any given day.

As monitoring capacity for—and interest in—volcanic eruptions increases, coverage of the activity more frequently appears in the news and on social media.Destruction of forests and farmlands Forests were destructed by the eruption of volcanoes in Malaysia.
