Volcanoes release ash, gas, and magma into the air and onto the ground. Earthquakes and tsunamis — Volcanoes and earthquakes share plates and because of this a volcano can set off an earthquake by creating movement in the plates. Lava flow — lava flow endangers people, property, and vegetation. Airborne lava fragments — Erupted piece of magma mostly endangers things and people directly in the vicinity of the volcano but can cause serious damage.

Volcanic eruptions are one of Earth's most dramatic and violent agents of change. Not only can powerful explosive eruptions drastically alter land and water for tens of kilometers around a volcano, but tiny liquid droplets of sulfuric acid erupted into the stratosphere can change our planet's climate temporarily.
Eruptions often force people living near volcanoes to abandon their land and homes, sometimes forever. Those living farther away are likely to avoid complete destruction, but their cities and towns, crops, industrial plants, transportation systems, and electrical grids can still be damaged by tephraashlaharsand flooding.
Fortunately, volcanoes exhibit precursory unrest that, when detected and analyzed in time, allows eruptions to be anticipated and communities at risk to be forewarned.
The warning time preceding volcanic events typically allows sufficient time for affected communities to implement response plans and mitigation measures. Hazard response and coordination plans are multi-agency efforts that define the responsibilities and actions to take in the event of a restless or active volcano.
Scientists from the five regional volcano observatories of the USGS Volcano Hazards Program participate in developing these plans with state and local governments of at-risk areas.
If volcanic unrest or an eruption occurs, scientists from the observatories will keep state and local officials informed of potential hazards so that coordination and response plans can be updated as needed.Living on a river may seem very appealing because you have beautiful and serene water views from the comfort of your home.
And depending on the size of the river, you might be able to swim, boat. A volcanic eruption can be an awesome and destructive event.
Here are some tips on how to avoid danger and what to do if you're caught near an eruption. • As much as possible, stay away from. What Are the Dangers of Living Near a Volcano? Lava, fragments and ash clouds from volcanoes all pose dangers to nearby residents and their property.
Hot lava from effusive volcanoes can kill people and burn plants and buildings. Volcanic eruptions are one of Earth's most dramatic and violent agents of change.
Eruptions often force people living near volcanoes to abandon their land and homes, sometimes forever. Those living farther away are likely to avoid complete destruction, but their cities and towns. A volcanic hazard refers to any potentially dangerous volcanic process (e.g.
lava flows, pyroclastic flows, ash).
A volcanic risk is any potential loss or damage as a result of the volcanic hazard that might be incurred by persons, property, etc. or which negatively impacts the productive capacity/sustainability of a .
Living on Active Volcanoes—The Island of Hawai'i People on the Island of Hawai`i face many hazards that come with living on or near active volcanoes.
These include lava flows, explosive eruptions, volcanic smog, damaging earthquakes, and tsunamis (giant seawaves).
