What is a positive effect of volcanoes?
Volcanoes can provide people with many benefits such as: volcanic rock and ash provide fertile land which results in a higher crop yield for farmers. tourists are attracted to the volcano, which increases money to the local economy. geothermal energy can be harnessed, which provides free electricity for locals.
What are the five volcanic materials?
Lava
- Chemical Composition Affects the Thickness and Shape of Lava Flows. The thickness and shape of a lava flow depends on its viscosity.
- Lava Structures. Pahoehoe.
- Volcanic Ash. Particles less than 2 mm in diameter are called volcanic ash.
- Lapilli.
- Blocks and Bombs.
- Effects of Gas on Lapilli and Bombs.
What are three products of a volcano?
The principal products of volcanic eruptions may be grouped into several broad categories according to the type of material ejected and its mode of transport from the vents to its place of deposition: ash, falls, pyroclastics flows, lava flow and gas emission.
Where lava is found?
Most are located around the Pacific Ocean in what is commonly called the Ring of Fire. A volcano is defined as an opening in the Earth’s crust through which lava, ash, and gases erupt. The term also includes the cone-shaped landform built by repeated eruptions over time.
Why do volcanoes attract tourists?
But they can also have advantages: – Volcanic ash contains many minerals which make the soil very fertile, – the earth’s crust around a volcano is so thin that it easy to win energy from the heat of the earth, – and volcanoes attract tourists.
Where are Mount Lokon and Mount Empung located?
Mount Lokon, together with Mount Empung, is a twin volcano (2.2 km or 1.4 mi apart) in the northern Sulawesi, Indonesia, roughly 10 km (6 mi) south of Manado.
How big is the crater on Lokon volcano?
Lokon, the higher of the two peaks (whose summits are only 2.2 km apart), has a flat, craterless top. The younger Empung volcano has a 400-m-wide, 150-m-deep crater that erupted last in the 18th century, but all subsequent eruptions have originated from Tompaluan, a 150 x 250 m wide double crater situated in the saddle between the two peaks.
When did the Mount Lokon volcano in Indonesia erupt?
An eruption occurred at 8:20, am the same day sending an ash plume two miles into the sky. Local residents have been evacuated from a two and a half mile exclusion zone around the volcano. An eruption occurred on 17 December 2012. Indonesia has 129 volcanoes including Mount Lokon.
How did Lokon volcano form in Tondano caldera?
Lokon formed during a period of andesitic volcanism on ring fractures resulting from the Tondano caldera ‘s early to mid-Pleistocene collapse. Recently erupted material remains andesitic in composition and consists of ash plumes and, less commonly, pyroclastic flows and lava domes.
