12th Workshop on Volcanic Lakes

Pampanga and Laguna, Philippines

March 9-18, 2026

IAVCEI Commission on Volcanic Lakes

Invitation

On behalf of the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI)-Commission on Volcanic Lakes (CVL) and the Department of Science and Technology – Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS), we are pleased to invite you to attend the 12th CVL Workshop.

The goal of the workshop is to bring together researchers from a wide range of disciplines such as physical volcanology, hydrology, limnology, biogeochemistry, geology, and hazard management, to share recent advances, foster collaborations, and discuss the latest approaches for the study of volcanic lakes and related environments.

CVL 12 is designed to offer both oral and poster scientific sessions and field visits to volcanic areas where crater lakes and maars exist.

General Information

Luzon and Weather

Luzon is the largest island in the Philippines, hosting the capital, Manila. March marks the beginning of the dry season, with warm and dry weather ideal for fieldwork. Average daytime temperatures range from 28–34°C.

Main Venue: Clark, Pampanga

The scientific sessions will be held in Clark, a modern economic zone approximately 80 km north of Manila (1.5-2.5 hours by car). It has excellent infrastructure, accommodations, and is close to field locations.

Airport Access

Flying into Clark International Airport (CRK) is highly recommended. It is only 15-20 minutes from the Clark Freeport Zone, avoiding Metro Manila's heavy traffic. While Manila’s Ninoy Aquino International Airport (MNL) is an option, ground travel from there can be lengthy.

Scientific Sessions

We invite ideas or proposals for up to 5 thematic symposia. The program aims to include sessions focused on:

  • Diffuse CO₂ degassing measurements and gaseous emissions from lakes
  • Geochemical and microbiological characterization of lake waters
  • Hydrogeological and geophysical modeling of lake environments
  • Active volcanism and phreatic events
  • Volcanic hazard assessment

Of particular interest is the occasional change in the color of Pinatubo Crater Lake, and we welcome contributions that explore this phenomenon.

Program Overview

Our 10-day workshop is packed with insightful scientific sessions, hands-on fieldwork, and networking opportunities. The program kicks off with two days of oral and poster sessions, followed by fieldwork at Pinatubo and the Seven Lakes of San Pablo.

Fieldwork Locations

Mount Pinatubo

Mount Pinatubo, Central Luzon

Famous for its cataclysmic 1991 eruption, Mount Pinatubo now features a stunning crater lake. It's a key site for geological studies. Field activities include water sampling, degassing measurements, and sediment studies.

San Pablo Maars

San Pablo Maars, Laguna

Known for its seven crater lakes formed by ancient maar volcanoes. These offer insights into phreatomagmatic eruptions. Opportunities for sediment core sampling, water degassing, and limnological profiling abound in this area.

Venue Information

The scientific sessions on March 9–10 will be held at one of the hotels in Clark, Pampanga.

Guests may also book their accommodations at the hotels listed below during their stay in Clark. We recommend reserving a room from your arrival in the Philippines up to March 11, as this ensures convenient access to the conference venue and nearby amenities before we depart together for the Pinatubo Crater workshop. On March 11, we will transfer to the designated Airbnb near Mt. Pinatubo for the next phase of the program.
