Iraya Vulkan
Updated: 16. Nov. 2025 23:53 GMT -
stratovolcano
Nördlich von Luzon (Philippinen), 20.47°N / 122.01°E 
Summit height: 1009 m / 3,310 ft
Aktueller Status: normal / ruhend (1 von 5)
Iraya is an active stratovolcano on Batan Island, 200 km north of Luzon, Philippines. It is the northernmost active volcano in the Philippines. Its last eruption probably happened in 1454 AD, but little details are known about this eruption.
It seems that Iraya volcano's eruptions were exclusively explosive, forming many pyroclastic flows. There are no lava flows.
In 1998, an earthquake swarm occurred beneath the volcano.

Beschreibung
The morphologically young Iraya volcano is the most prominent feature of the 20-km-long Batan island. It has a 1.5-km-wide summit crater largely filled by a younger cone that forms the present-day summit. 2 older volcanoes form the rest of Batan Island:Mahatao volcano is the oldest and was active until the late Miocene (ca. 5 million years ago), and forms the center of Batan Island. Matarem volcano in the south was active until about 2 million years ago (early Pleistocene).
Iraya belongs to the Babuyan Segment, the least evolved of 4 segments of the Luzon volcanic arc. It has developed on the western part of the Philippine plate, where the South China oceanic and Eurasian plates are being subducted along the Manila Trench.
There are three volcanoes on Batan Island. Iraya volcano is located in the north of the island and has been active since Late Pleistocene.

Anmerkung:
Unsere Liste von Vulkanausbrüchen orientiert sich eng an der Datenbank des Global Volcanism Project (GVP) des Smithsonian Instituts, der international anerkanntesten globalen Datenquelle für Vulkanausbrüche. Sie schließt aber auch bedeutende Eruptionsepisoden oder damit zusammenhängende Vulkanereignisse ein. Unter "Vulkanausbrüchen" versteht man in der Regel meist Serien einzelner Eruptionsepisoden, die zeitlich aufeinander folgen oder sich (bei mehreren beteiligten Ausbruchspunkten an einem Vulkan) auch überlappen können und unter Umständen viele Jahre, Jahrzehnte oder noch länger andauern können. So ist z.B. die aktuelle Tätigkeit des Stromboli als ein einziger Ausbruch verstanden, der seit 1934 anhält.
