Winds lift ash from 1912 Alaskan volcanic eruption – Medford News, Weather, Sports, Breaking News
ANCHORAGE, Alaska – Volcanoes scientists issued an alert on Wednesday, warning that an ash cloud – from an eruption more than a century ago – was heading towards Kodiak Island in Alaska.
The ash comes from the powerful 1912 eruption of Novarupta, a volcano in the Alaska Peninsula that dropped volcanic ash that can still be seen today.

Strong northwesterly winds near Katmai National Park and Preserve and Valley of Ten Thousand Smokes on Wednesday lifted ash from the volcano.
âUsually at this time of year we get those northwesterly winds that can come down from the Katmai area and really erode some of the loose ash that settled in the 1912 eruption and then bring it up. at the height, “Hans Schwaiger, a US Geological Survey research geophysicist at the Alaska Volcano Observatory, told The Associated Press.
Winds were expected to carry the ash approximately 100 miles (161 kilometers) southeast toward Kodiak Island, and an aviation aircraft alert was issued for the low level event. Scientists estimated that the cloud would not exceed 7,000 feet (2,133.6 meters).
Some of these events can cause a light dusting of ash in neighboring communities.
âThis one appears not to be as ash-rich as some of the others, so there will likely be negligible ash fallout,â Schwaiger said.
The three-day eruption of Novarupta, one of the largest in the world, began on June 6, 1912 and sent ash up to 100,000 feet (30,480 meters) above the Katmai region, located about 250 miles (402 kilometers) southwest of Anchorage. The US Geological Survey estimates that 3.6 cubic miles (15 cubic kilometers) of magma erupted, about 30 times what was spewed out of Mount St. Helens in Washington state 40 years ago.
The eruption of Novarupta was the most powerful of the 20th century and ranks among the most important in recorded history.
The ashes were deposited in what is now known as the Valley of Ten Thousand Smokes, depositing about 600 feet (183 meters) of ash in places.
High winds and dry, snowless conditions will produce these ash clouds intermittently, the observatory said in a statement, adding that there was no eruption in place.
The statement said all seven volcanoes in the Katmai region, including Novarupta, remain at the lowest level of green, or normal.
Kodiak Island has a population of approximately 13,000 and is home to a large US Coast Guard base. It is only accessible by plane and ferry. The fishing industry is the predominant activity on the mountainous island.
