Hawaiian volcano spewing more lava than usual
| Quote From Source: | VOLCANO, Hawaii (AP) - More lava than usual is erupting from Hawaii's Kilauea volcano into the ocean.
The Hawaiian Volcano Observatory said Saturday the lava is flowing from an outbreak that started Nov. 21 as a continuation of the volcano's 25-year eruption.
Surface flows emerge near the ocean on the southeast side of the Big Island, where people can see the lava from a viewing area a few hundred feet away.
A white plume rising from the Halemaumau vent near Kilauea's summit is carrying small amounts of ash and elevated levels of sulfur dioxide.

Sometimes these stories are really insignificant, perhaps interesting at the best. Every once in a while though, its a precursor to much bigger things.
They should take the warning labels off of everything and let stupidity sort itself out.

What is it about Kilauea that allows it to erupt continuously for decades like that? How is it different from a Tambora or Krakatoa? |

Hot spot dynamics
Because the source of heat is the nuclear core of a galactic cruiser, that crashed into Earth millions of years ago (jk) it melts basaltic rock under the sea floor, that comes to the surface like wax running down a candle.
The explosive volcanoes occur along subduction zones and the remelted rock that comes back to the surface, was mostly limestones and other rocks that produce lots of CO2 when they melt producing massive gas problems at time of eruptions. |

| Quote From Source: | First, let's review why we worry about SO2. Kilauea is currently producing up to 4,000 tonnes/day of SO2, resulting in concentrations in air greater than 5 parts per million (ppm) in downwind communities within 50 km (31 miles). Sustained concentrations greater than 0.3 ppm are considered unhealthy. During its journey through the air, the SO2 reacts with oxygen, sunlight, and water to form vog, a mixture of gas and tiny sulfuric acid aerosol droplets. This aerosol mixture appears as a dense haze that obscures Hawaiian scenery and ocean views. The acidic droplets in vog are small enough that they can be inhaled deep in the lung and can pose health problems. In addition to the effects on living creatures, the acid mist can acidify rain and burn the leaves of plants, including many agricultural crops, such as protea, roses, fruits, and vegetables.
The most abundant constituent of eruptive emissions is water, but that's nothing to worry about. We can always use more water, and Kilauea adds more than 4,000 gallons per minute in the form of water vapor to the Earth's water supply. Carbon dioxide (CO2) is the second most abundant constituent in Kilauea emissions. Current CO2 emission rates are about 10,000 tonnes/day. We already have CO2 in concentrations of 0.04 percent and more in the air that we breathe, thanks to human-generated emissions. Fortunately, plants photosynthesize some of this to make oxygen. CO2 is heavier than air and can be a problem in low-lying areas immediately downslope of a volcanic vent when its concentrations exceed 5 percent. Worldwide, human activities produce more than 100 times the amount of CO2 emitted by volcanoes. So although Al Gore is worried about CO2 he isn't blaming volcanoes.
Water, SO2, and CO2 comprise about 99 percent of Kilauea's emissions. All the other constituents together account for the remaining 1 percent and there are many of them. Hydrogen (H2), Hydrogen Chloride (HCl), Hydrogen Fluoride (HF), and Carbon Monoxide (CO) are the principal minor constituents. Of these, H2 and CO are already in the atmosphere at trace levels.

seems a bit more than a couple semi's blowing black smoke on the highway to me....
