How global warming shakes the Earth: Seismic data show ocean waves gaining strength as the planet warms - PreventionWeb
Emerging research reveals a previously unquantified consequence of global warming: amplified seismic activity linked to intensifying ocean waves. Utilizing a network of seismic sensors, scientists have documented a measurable increase in low-frequency ground vibrations correlated with rising sea temperatures and wave energy. This phenomenon highlights the far-reaching impacts of climate change, extending beyond surface observations.
What is the deepest point on the ocean floor in Indian EEZ?
The Indian Exclusive Economic Zone (EEZ) does not contain a trench comparable to the Mariana Trench, the deepest known point globally. However, the ocean floor within the Indian Ocean reaches significant depths. Empirical data, as detailed in a recent *ScienceDirect* article, indicates depths exceeding 6,000 meters in certain regions. Globally, ocean floors can descend to over 11,000 meters.
Forces deep inside Earth helped Antarctica freeze before the Arctic
Scientists have advanced our understanding of Antarctica’s early glaciation, positing that deep Earth forces played a pivotal role. Empirical evidence suggests slow-moving waves within the Earth gradually uplifted East Antarctica, creating a high-altitude plateau conducive to ice accumulation millions of years prior to the Arctic's freeze. This elevation facilitated snow and ice survival even during warmer periods, and once established, glacial surfaces amplified cooling through increased solar reflection.
They were drilling off Oregon. What they found could shake the entire West Coast
Recent deep-sea drilling off the Oregon coast has yielded a concerning discovery: evidence suggests a major Cascadia earthquake could trigger a subsequent rupture on the San Andreas Fault. Analysis of sediment layers, recording millennia of underwater landslides, reveals historical instances of both fault systems activating in close proximity. This finding elevates concerns about a potential, cascading earthquake sequence impacting the entire West Coast. For further exploration of related oceanic impacts, see our article, "PHYS.
