A volcanic tremor lasting 10 hours and 30 minutes was observed at Taal volcano on Saturday, indicating sustained magmatic or hydrothermal activity beneath the surface. Such prolonged tremors are often associated with the movement of magma, volcanic gases, or fluids, which can cause increased pressure within the volcano’s system. This could lead to further unrest,…
New activity/unrest was reported for 2 volcanoes from October 2 – 8, 2024. During the same period, ongoing activity was reported for 20 volcanoes.
