(A patera is a bowl-shaped volcanic crater.) The most active volcanic site on Io, which itself is the most volcanically active body in the solar system, Loki Patera is about 200 kilometers (127 miles) across.
The hot region of the patera has a surface area of 21,500 square kilometers, larger than Lake Ontario.
Where is the largest volcano crater?
Caldera lakes in contrast can be quite large and long-lasting. For instance, Lake Toba (Indonesia) formed after its eruption around 75,000 years ago. At a size of around 100 km (60 miles) by 30 km (18 miles) in extent and 505 m (1,656 ft) deep at its deepest point, Lake Toba is the largest crater lake in the world.
How deep is a volcanic crater?
The fractured rock above the magma chamber collapsed to produce a massive crater over six miles across. Centuries of rain and snow filled the caldera, creating Crater Lake. With a depth of 1949 feet (594 meters), Crater Lake is the deepest lake in the United States and the ninth-deepest lake in the world.
What is the size of Ngorongoro Crater?
The crater, which formed when a large volcano exploded and collapsed on itself two to three million years ago, is 610 metres (2,000 feet) deep and its floor covers 260 square kilometres (100 square miles). Estimates of the height of the original volcano range from 4,500 to 5,800 metres (14,800 to 19,000 feet) high.
How big was the meteor that made Crater Lake?
Barringer Meteor Crater and Its Environmental Effects. Forty-nine thousand years ago, a large 30 to 50 meter diameter iron asteroid impacted the Colorado Plateau in northern Arizona. The resulting massive explosion excavated 175 million tons of rock, forming a crater nearly a mile wide and 570 feet deep.

Which is the largest crater lake in Africa?
Ngozi Crater – the second largest crater lake in Africa. This picturesque crater-lake is situated in the south of Tanzania, roughly 38km from the city of Mbeya on the way to Lake Malawi. Geographically the crater is part of the Mporoto Ridge forest reserve with Ngozi peak at 2620m the highest point of the ridge.
Is Crater a volcano?
A volcano crater is a circular depression around a volcanic vent. This is where the lava, ash and rock erupt out of a volcano. In most situations, the volcano crater is located at the top of the volcano.
What is the opening of a volcano called?
Vent – An opening in Earth’s surface through which volcanic materials escape. Lava – Molten rock that erupts from a volcano that solidifies as it cools. Crater – Mouth of a volcano – surrounds a volcanic vent. Throat – Entrance of a volcano.

Tanzania
How old is Ngorongoro Crater?
The crater is the flagship tourism feature for the Ngorongoro Conservation Area. It is a large, unbroken, un-flooded caldera, formed when a giant volcano exploded and collapsed some three million years ago. The Ngorongoro crater sinks to a depth of 610 metres, with a base area covering 260 square kilometres.
Is Ngorongoro Crater in the Serengeti?
Interactive Map of Serengeti, Ngorongoro and Lake Manyara. The Ngorongoro Crater, once a gigantic volcano, is the largest intact caldera in the world. Today, long since having collapsed and eroded, it is an extensive highland area with the famous 600-meter-deep Ngorongoro Crater as its focal point.
Was crater lake formed by a meteor?
This is not a meteor crater – a hole made by the impact of a big rock from space – so there is no meteor to find. Rather, this is a volcanic caldera – a hole made by the collapse of a volcano. Yes, and there still is! 7,700 years ago, the volcano erupted in a cataclysmic eruption.
Will Crater Lake erupt again?
The long history of volcanic activity at Crater Lake suggests strongly that this volcanic center will erupt again. The most recent eruptions occurred on the lake floor in the western part of the caldera. Future eruptions are more likely to occur in the same area than farther east.
Is Crater Lake still active?
It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a nearly 2,148-foot (655 m)-deep caldera that was formed around 7,700 (± 150) years ago by the collapse of the volcano Mount Mazama.
What is the biggest volcano in the world 2018?
For a long time, scientists thought the Kilauea volcano was just a small satellite of its much larger neighbor, Mauna Loa, the largest active volcano in the world. But more recent findings revealed that Kilauea has its own magma plumbing system extending nearly 40 miles below the earth’s surface.
What is the most powerful volcano in the world?
Here are some of the biggest, most destructive volcanic eruptions on Earth:
- Mount Vesuvius – Pompeii, Roman Empire (now Italy) – 79.
- Laki – Iceland – 1783.
- Tambora – Indonesia – 1815.
- Krakatoa – Sunda Strait, Indonesia – 1883.
- Novarupta – Alaska Peninsula – June, 1912.
- Mount St.
- Mount Pinatubo – Luzon, Philippines – 1991.
Is Yellowstone the largest volcano?
The Island Park Caldera supereruption (2.1 million years ago), which produced the Huckleberry Ridge Tuff, was the largest, and produced 2,500 times as much ash as the 1980 Mount St. Helens eruption. The next biggest supereruption formed the Yellowstone Caldera (~ 630,000 years ago) and produced the Lava Creek Tuff.
What happens if Yellowstone blows?
If the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could spew ash for thousands of miles across the United States, damaging buildings, smothering crops, and shutting down power plants. In fact, it’s even possible that Yellowstone might never have an eruption that large again.
How many survived Pompeii?
It is estimated that from 1,500 to 2,000 people died in Pompeii during the 79 AD eruption; most scholars believe that the number of inhabitants of the city was somewhere between 6,000 to 20,000; therefore most Pompeians survived the pyroclastic clouds, possibly because, alerted from the early signs of the eruption,
Will Yellowstone erupt soon?
Yellowstone volcano is estimated to have lest erupted 640,000, 1.2 million and 2.1 million-years-ago. Any signs of imminent eruption will be preceded by earthquakes, ground uplift and unusual volcanic activity.
When was the last eruption of Crater Lake?
Crater Lake partially fills a type of volcanic depression called a caldera that formed by the collapse of a 3,700 m (12,000 ft) volcano known as Mount Mazama during an enormous eruption approximately 7,700 years ago.
What kind of volcano is Crater Lake Oregon?
Crater Lake volcano. Crater Lake in the southern Cascade Range of Oregon, USA, is one of the most beautiful calderas in the world. It formed by the collapse of a massive stratovolcano known as Mount Mazama about 6850 years ago. The caldera measures 8×10 km in diameter and is filled with a lake of up to 600 m depth.
What are the three main types of volcanoes?
There are three main types of volcano – composite or strato, shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. The eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava.
What is a volcano that is currently erupting called?
An erupting volcano is an active volcano that is having an eruption A dormant volcano is an active volcano that is not erupting, but supposed to erupt again. An extinct volcano has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.
What is the opening from which lava erupts called?
Lava erupts through an opening in Earth’s crust called a. vent. A bowl-shaped depression that forms around the vent of a volcano is a. crater. You just studied 35 terms!
What is lava shooting from a volcano called?
Lava domes are formed when erupting lava is too thick to flow and makes a steep-sided mound as the lava piles up near the volcanic vent. The eruption of Mount St. Helens in 1980 was caused in part by a lava dome shifting to allow explosive gas and steam to escape from inside the mountain.
Where is the highest volcano in the world?
Chile
What caused Ngorongoro Crater?
Ngorongoro Crater, extinct volcanic caldera in the Eastern (Great) Rift Valley, northern Tanzania. Ngorongoro is thought to have formed about 2.5 million years ago from a large active volcano whose cone collapsed inward after a major eruption, leaving the present vast, unbroken caldera as its chief remnant.
Was the Ngorongoro crater was formed by a meteor strike?
The Ngorongoro Crater was formed when a giant volcano exploded and collapsed around 3 million years ago. The cone of the volcanic caldera collapsed inwards and created what we know today as one of the most unique safari parks in Africa, and indeed the world. A one of a kind safari destination teeming with life.
