Definition of lava dome in English: lava domenoun A mound of viscous lava which has been extruded from a volcanic vent. Example sentencesExamples - Rising magma continues to build a lava dome in the crater of Mount St. Helens.
- In the last several days, the roughly 1,000-foot-tall lava dome has risen by about 150 feet.
- At Mount St. Helens, a lava dome continues to grow inside the volcano's horseshoe-shaped crater.
- A cluster of seven lava domes found in the eastern part of Alpha Regio.
- Geologists said the lava dome inside the volcano is now deforming, or growing, by tens, maybe hundreds, of feet.
- About nine years ago, I visited that particular volcano, actually flew on a helicopter right to that lava dome at the center of that crater.
- Thermal and textural anomalies seen on the surface of the lava domes change markedly during the restive state prior to larger eruptions.
- Several earlier lava domes formed after May 18, 1980 had been removed by explosive eruptions.
- However, current field analyses of the flow structures suggest the outcrops are individual lava domes.
- Geological Survey crews also observed a shift in the crater floor and on part of the 1,000-foot lava dome that essentially serves as a plug for magma, he said.
- Its 2,000-foot height and nearly 2-cubic kilometer volume make it one of the largest lava domes in the world.
- Slowly rising lava domes may grow for months or for several years in the aftermath of explosive eruptions.
- The lower hills at left and at right are lava domes belonging to the Amiata complex.
- Generally, newly erupted lava domes grow in an endogenous regime of growth that represents a thermo-mechanical continuum.
- The peninsula of Methana is made of lava domes and lava flows.
- Experts watching a recent spike in volcanic activity say a lava dome in the mountain's crater is growing.
- And it all depends on what's happening under the volcano in the magma body under the lava dome, whether this system will continue to repressurize or not.
- The Pitons are the remnants of two lava domes that formed about 200-300 thousand years ago.
- Many lava domes grow by internal intrusion of lava that causes swelling and oversteepening of the dome.
- The eruption has been characterized by lava dome extrusion, dome-collapse pyroclastic flows and explosive activity.
