Hundreds of articles have been written about the largest volcanic eruption in recorded history, at Indonesia’s Mt. Tambora just over 200 years ago. But for a small group of New England-based researchers, one more Tambora story needed to be told, one related to its catastrophic effects in the Gulf of Maine that may carry lessons for intertwined human-natural systems facing climate change today.
In early September of 2010, a pattern of increased earthquake activity occurred at the Mount Merapi volcano in Indonesia. A few days later, an avalanche was observed south of the mountain, and white plumes were seen rising above the crater. A lava dome detected in March began to increase rapidly.
There are approximately 1,550 potentially active volcanoes around the world. VDAP works to reduce loss of life and property, limit economic impact and prevent volcanic crises from becoming disasters.
The world’s largest volcanic eruption to happen in the past 100 years was the June 15, 1991, eruption of Mount Pinatubo in the Philippines.
In November 1985, a lahar (volcanic mudflow) originating from Nevado del Ruiz volcano inundated the town of Armero, destroying all infrastructure in its path and killing 23,000 people. VDAP was developed in response to this tragedy. Photograph credit: USGS/VDAP

USGS scientists recount their experiences before, during and after the May 18, 1980 eruption of Mount St. Helens. Loss of their colleague David A. Johnston and 56 others in the eruption cast a pall over one of the most dramatic geologic moments in American history.

The fume source near the base of Mauna Loa (at Kīlauea's summit) is from the Halema`uma`u Overlook vent. The wind is blowing the plume trace toward the northeast, partially obscuring the view of Mauna Kea.
The eruption of Mount Pinatubo sent lahars and pyroclastic flows down the mountain, wiping out bridges and other infrastructure downstream.

On Sunday, May 18, 1980 at 8:32 a.m., the bulging north flank of Mount St. Helens slid away in a massive landslide -- the largest in recorded history. Seconds later, the uncorked volcano exploded and blasted rocks northward across forest ridges and valleys, destroying everything in its path within minutes.
