Smith Volcano, also known as Mount Babuyan, is a cinder cone on Babuyan Island, the northernmost of the Babuyan group of islands on Luzon Strait, north of the main island of Luzon in the Philippines. The mountain is one of the active volcanoes in the Philippines , which last erupted in 1924.
A dormancy of about 4,000 years was broken around 2500 BC with the start of the Smith Creek eruptive period, when eruptions of large amounts of ash and yellowish-brown pumice covered thousands of square miles. [13]: 215 An eruption in 1900 BC was the largest known eruption from St. Helens during the Holocene epoch, depositing the Yn tephra.
This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the volcanic winter of 536); its effect on the climate may have been exacerbated by the 1814 eruption of Mayon in the Philippines. The significant amount of volcanic ash and gases released into the atmosphere blocked sunlight, leading to global cooling.
The historic Mount St. Helens eruption occurred 44 years ago, but it still remains an active volcano today.
Babuyan Claro Volcano, also known as Mount Pangasun, is an active volcano located on Babuyan Island, the northernmost of the Babuyan group of islands in Luzon Strait, north of the main island of Luzon in the Philippines. It is classified as one of the active volcanoes of the country with the last confirmed eruption in 1860. [2]
2018: Anak Krakatau . The volcanic island of Anak Krakatau in Indonesia saw an eruption on 22 December 2018 which caused a deadly tsunami, with waves surging up to five meters in height.
The Yn tephra is a geologically recent tephra deposit that covers portions of the U.S. state of Washington and the Canadian provinces of British Columbia and Alberta.It was created by the largest known volcanic eruption from Mount St. Helens, having taken place in possibly 1860 BCE as part of the Smith Creek eruptive period.
The volcano that produced the 1808/1809 eruption remains unknown. The addition of Zavaritskii highlights the potential of volcanoes in the Kuril Islands for disrupting Earth’s climate, the study ...
