The ages of the volcanoes are systematically
younger toward
the southeast, and the bend in the chain separates the older Emperor Seamount Chain from the younger Hawaiian Ridge. The oldest dated volcano near the northern end of the Emperor Seamount Chain is 81 million years.
Are the Hawaiian chain and the Emperor seamount chain the same age explain?
(Public domain.) The ages of the volcanoes are
systematically younger toward the southeast
, and the bend in the chain separates the older Emperor Seamount Chain from the younger Hawaiian Ridge. The oldest dated volcano near the northern end of the Emperor Seamount Chain is 81 million years.
What is the age and location of the Emperor seamount chain relative to the Hawaiian Islands chain?
| Name | Colahan | Type | Seamount | Coordinates | 31°15′N 176°0′E | Age | K-Ar 38.7±0.2 million | Notes | — |
|---|
How is the age distribution pattern of the Emperor seamount and Hawaiian island chains explained by the position of the Hawaiian hotspot?
The volcanoes in the Hawaiian Island-Emperor Seamount chain
get progressively older as one heads northwestward from Hawaii
. These age relationships suggest that the Pacific Plate
When did the Hawaiian Emperor Seamount chain form?
The Hawaiian plume originates from the edge of this province and the southward migration of the plume during the formation of the Emperor chain reflects the migration of the northern edge of the LLSVP before
~47 million years ago
.
Where in the chain is the oldest volcano where is the youngest?
Hawaii
is the youngest of a long line of volcanoes called the Hawaiian-Emperor Sea Mount chain. The oldest volcano in the chain is the inactive volcano Meiji, which is 85 million years old.
What part of the Hawaiian island chain is the oldest?
The Leewards
are the oldest islands of the Hawaiian chain
What Hawaiian island has an active volcano?
The Island of Maui
has one active volcano, Haleakalā, which has erupted at least 10 times during the past 1,000 years. Kīlauea
Why is the Emperor seamount Hawaiian chain bent in the middle?
The cause for this bend has been heavily debated for decades. One explanation is
an abrupt change in the motion of the Pacific tectonic plate
, the opposite model states southward drift of the mantle plume
Why do oceans become deeper moving away from ridges?
Oceans become deeper moving away from ridges due to?
thermal contraction of hot lithosphere
.
What is the largest volcano in the world?
Mauna Loa on the Island Hawaiʻi
is the world's largest volcano. People residing on its flanks face many hazards that come with living on or near an active volcano, including lava flows, explosive eruptions, volcanic smog, damaging earthquakes, and local tsunami (giant seawaves).
Why is there a hotspot under Hawaii?
The Hawaiian Islands were
literally created from lots of volcanoes
—they're a trail of volcanic eruptions. Hot-spot volcanism can occur in the middle of tectonic plates. That's unlike traditional volcanism, which takes place at plate boundaries.
What are the 7 islands of Hawaii?
- Kauai.
- Oahu.
- Molokai.
- Lanai.
- Maui.
- Hawaii.
Which is the smallest volcano in the world?
The Cuexcomate
is known as “the smallest volcano in the world” and it is located just 15 minutes away from downtown Puebla in central Mexico.
How long does an island chain last?
While the process by which volcanic islands form is similar from chain to chain, the time that any island spends above sea level can vary widely, from
a few million years in the case of the Galapagos to over 20 million for the Canary Islands
. An island's age can determine the life and landscapes that evolve there.
How old is the youngest volcano?
| Parícutin | Age of rock 1941–1952 | Mountain type Cinder cone | Volcanic arc/belt Trans-Mexican Volcanic Belt | Last eruption 1943 to 1952 |
