Glaciers are formed by centuries of accumulating snowfall, which gradually compresses into solid ice. As each layer forms, it traps ambient air bubbles, dust, and critically, volcanic ash (tephra). By drilling deep into the ice sheets of Greenland and Antarctica, glaciologists extract long cylinders known as ice cores. These cores serve as vertical timelines. A distinct layer of dark tephra or a spike in sulfate acidity within a specific ice layer points directly to a historical volcanic event, allowing scientists to date eruptions with extraordinary chronological precision.

Filling in gaps with exact words from the text.

The passage states the exact opposite. Subglacial eruptions are often more hazardous because they trigger instant flash flooding and explosive steam interactions alongside standard lava flows.
