Taal Volcano

At a glance

Dates: From 2020.

What came beforeAI-assisted

Taal Volcano formed through multiple eruption cycles over hundreds of thousands of years. The caldera itself developed from prehistoric eruptions occurring between less than 670,000 and less than 6,000 years ago, with earlier cone structures like Batulao, Macolod, and Sungay marking the pre-caldera Taal system.

By the 16th century, Spanish colonizers documented the volcano's activity and established settlements around Taal Lake despite its hazards. The volcano had already demonstrated its dangerous nature through 39 confirmed historical eruptions before the January 2020 event.

What happened

Taal Volcano, also known as Taal Caldera, is a large caldera filled by Taal Lake in the Philippines. Located in the province of Batangas about 50 kilometers (31 mi) south of Manila, the volcano is the second most active volcano in the country, with 39 confirmed historical eruptions, concentrated on Volcano Island, near the middle of Taal Lake. The caldera was formed by prehistoric eruptions between less than 670,000 and less than 6,000 years ago. The cones Batulao, Macolod,
