On top of that, Iceland happens to sit on top of a big bubble of magma, which incidentally is the same bubble that pushes Iceland up to the CascadesVolcano Monitoring. USGS Cascades Volcano scientists listen to and watch volcanoes using a variety of equipment. Seismometers detect earthquakes, GPS receivers detect ground motion, "sniffers" detect volcanic gas, and staff innovate new equipment to solve unique activity detection needs. KawahIjen is a volcano found in eastern Java, Indonesia. At night, it comes alive with blue fire as its sulphur deposits catch light. Tourists flock to the volcano to see the blue flames. Nearly22,000 people have been evacuated or displaced and many are in need of food, water and basic healthcare. Indonesia: Mt. Merapi Volcano - Oct 2010; Indonesia: Sumatra Earthquake - Sep 2009; Askthem to consider why the extinct volcanoes tend to be close to the active volcanoes. Given what they know about the active volcanoes, have students identify the past source of the extinct volcano.To extend this activity, have students research and plot the locations of the other volcanoes in the Hawaiian-Emperor seamount chain. Whatis Lava? When a volcano erupts, the molten rock (or magma) that comes out of the Earth is called lava. Because lava is so hot (more than 1,100 degrees C, over 2,000 degrees F), it remains molten and flows across the ground until it cools and hardens into rock. Lava is the most common form of material erupted from volcanoes that form OverviewVenus has more volcanoes than any other planet in the solar system. Over 1600 major volcanoes or volcanic features are known (see map), and there are many, many more smaller volcanoes. (No one has yet counted them all, but the total number may be over 100,000 or even over 1,000,000). These volcanoes come in a variety of forms. Most are either Large Shields or Smaller Shield volcanoes MaDDrea.
