the de-glaciation of the planets could impact the degree of volcanic eruptions.

Weighing the Seismic Consequences of Water
In order to make any connection between climate and earthquakes, says Lundgren, you first have to determine what kinds of tectonic processes might be related to climate phenomena. Scientists know earthquakes can be triggered or inhibited by changes in the amount of stress on a fault. The largest climate variable that could change fault stress loads is surface water in the form of rain and snow. Lundgren says several studies have supported such correlations. But there’s a catch.
“Typically, where we’ve seen these types of correlations is in microseismicity — tiny earthquakes with magnitudes less than zero, far smaller than humans can feel,” he said. “Those occur quite frequently.”
Lundgren cited work by his colleague Jean-Philippe Avouac at Caltech and others, who’ve found a correlation between the amount of microseismicity in the Himalaya and the annual monsoon season. During the summer months, large amounts of precipitation fall on the Indo-Gangetic Plain, which encompasses the northern regions of the Indian subcontinent. This increases stress loads on Earth’s crust there and decreases levels of microseismicity in the adjacent Himalaya. During the winter dry season, when there’s less water weight on Earth’s crust in the plain, Himalayan microseismicity peaks.
Fire and Ice: Glaciers and Tectonic Processes
Another climate-related phenomenon that’s believed to have connections to tectonic processes is glaciation. The retreat of a glacier can reduce stress loads on Earth’s crust underneath, impacting the movement of subsurface magma. A recent study in the journal Geology on volcanic activity in Iceland between 4,500 and 5,500 years ago, when Earth was much cooler than today, found a link between deglaciation and increased volcanic activity. Conversely, when glacial cover increased, eruptions declined.
The rapid movement of glaciers has also been shown to cause what are known as glacial earthquakes. Glacial earthquakes in Greenland peak in frequency in the summer months and have been steadily increasing over time, possibly in response to global warming.
Human Uses of Water and Induced Seismicity
In addition to climate-related impacts of water on seismicity, human management and applications of water can also affect earthquakes through a phenomenon known as induced seismicity.
For example, water stored in large dams has been linked to earthquake activity in various locations around the world, though the impact is localized in nature. In 1975, approximately eight years after Northern California’s Lake Oroville, the state’s second-largest human-built reservoir, was created behind the Oroville Dam, a series of earthquakes occurred nearby, the largest registering magnitude 5.7. Shortly after the water in the reservoir was drawn down to its lowest level since it was originally filled in order to repair intakes to the dam’s power plant and then refilled, the earthquakes occurred.
