This was the view from the Mauna Loa Strip Road in Hawai`i Volcanoes National Park at 7 a.m. this morning. Stagnant surface winds, combined with higher elevation winds from the southwest, caused the plume to rise straight up and then shear off to the northeast.

2008 - index OSEI volcano products include multichannel color composite imagery showing ash clouds (VSH), hotspots from lava flow (VIR) or both (VOL). We also create grayscale "split-window" images which use a channel differencing technique that enhances the appearance of ash clouds in imagery (DIF). This technique is oftenuseful for distinguishing ash clouds from water vapor clouds.

Photograph courtesy NASA Earth Observatory When thick magma and large amounts of gas build up under the surface, eruptions can be explosive, expelling lava, rocks and ash into the air. Less gas and more viscous magma usually mean a less dramatic eruption, often causing streams of lava to ooze from the vent. The mountain-like mounds that we associate with volcanoes are what remain after the material spewed during eruptions has collected and hardened around the vent. This can happen over a period of weeks or many millions of years. A large eruption can be extremely dangerous for people living near a volcano. Flows of searing lava, which can reach 2,000 degrees Fahrenheit (1,250 degrees Celsius) or more, can be released, burning everything in its path, including whole towns. Boulders of hardening lava can rain down on villages. Mud flows from rapidly melting snow can strip mountains and valleys bare and bury towns. Ash and toxic gases can cause lung damage and other problems, particularly for infants and the elderly. Scientists estimate that more than 260,000 people have died in the past 300 years from volcanic eruptions and their aftermath. About 1,900 volcanoes on Earth are considered active, meaning they show some level of activity and are likely to explode again. Many other volcanoes are dormant, showing no current signs of exploding but likely to become active at some point in the future. Others are considered extinct.

The Topic:
Easier -A volcano is a mountain topped with vents, holes, and craters. When the volcano erupts, lava, ash, cinders, dust, and hot gas can pour out the top. Magma (when it's deep in the ground) or lava (when it reaches the earth's surface) is very hot, liquid rock. When the lava cools down, it turns into hard rock. Ash is a gray powder that results from material being burned in the volcano. Ash can be carried in the air for many miles. Harder - Volcanoes occur along the earth's tectonic plates where molten rock is forced upward from magma reservoirs deep in the earth. The magma may be fifty to one hundred miles below the ground. As the magma rises, it gives off gases that cause an explosion in the vents of the volcano. Lava can reach temperatures of over 2000 degrees F. Molten rock, dust, and gases push through the opening in the earth's crust and form a mountain. A violent explosion can cause the top of the volcano to blow off leaving a deep crater. There are four types of volcanoes: active, intermittent, dormant, and extinct. Volcanoes can occur on land or in the water.

Recent Kilauea Status Reports, Updates, and Information Releases
Thursday, May 29, 2008 07:45 HST (Thursday, May 29, 2008 17:45 UTC)
Volcano Alert Level: WATCH
Aviation Color Code: ORANGE
This report on the status of Kilauea volcanic activity, in addition to maps, photos, and webcam images (available using the menu bar above), was prepared by the USGS Hawaiian Volcano Observatory (HVO). Information on the status of Hawai`i Volcanoes National Park can be found at or 985-6000. Information on the Hawai`i County Viewing Area can be found at or 961-8093.
Activity Summary for last 24 hours: No significant changes. Kilauea Volcano is active at two locations. At the summit, small amounts of ash and elevated amounts of sulfur dioxide continued to erupt from the Halema`uma`u vent. At the east rift eruption site, lava continued to erupt from the TEB vent area and flow through tubes to the ocean.
Last 24 hours at Kilauea summit: Molten lava probably exists at shallow depth within the new vent, but cannot yet be seen directly from the surface. The incandescence seen at night is caused by wall rock heated by the radiant molten lava below and the gas released and rising up through the vent.

70. Volcanos
Note Volcanos like Mt. St. Helens can explode. That s because there is water in the lava (remember, the lava came from under the ocean originally).
Mount Saint Helens, just north of the Columbia River. Note: Volcanos like Mt. St. Helens can explode. That's because there is water in the lava (remember, the lava came from under the ocean originally). The water is really hot, and when some of the pressure is released, it can turn to steam. That makes its volume much bigger, so the mountain can get blasted into the air. You may recall that there is a big volcano in Hawaii, which doesn't explode. There are two reasons. First, the lava in volcanos like this is a lot less viscous, so water vapor bubbles can more easily bubble up to the surface instead of pushing the lava up. Second, there is less water (0.5% by weight instead of 5%). Thanks to Prof. K. Cashman for help on this. Take a class from her if you want to learn about volcanos.
