Personally, I think marine earthquakes are more terrifying. Land earthquakes usually only affect land areas, while marine earthquakes can easily cause tsunamis, which are usually very severe. Huge waves push over land, harming people on land as well as marine life.
So what exactly is an underwater earthquake? Is it as simple as a simple earthquake transferred to the seabed? Underwater earthquake Underwater earthquake An earthquake is a sudden movement that occurs when underground rocks suddenly break apart. The relative movement and interaction of lithospheric plates along their boundaries is the primary cause of underwater earthquakes. Typically, underwater earthquakes occur thousands of meters under the sea, so small earthquakeshave little impact, but large earthquakes can cause great disasters to humans, and some are more terrifying than land earthquakes!
The damage caused by earthquakes at sea is even more terrible. I believe the 2004 Indian Ocean earthquake is still fresh in everyone's memory. The magnitude of this underwater earthquake was 9.0, causing the most terrifying tsunami in modern times! This caused a large number of casualties, with the death toll exceeding 230,000, which is chilling. At that time, seismic experts believed that the strata were affected by this strong earthquake and were actively active, and that large-scale earthquakes would occur in South Asia in the coming years. As a result, on March 28, 2005, a strong earthquake with a magnitude of 8.7 occurred in Sumatra. These two trembledExtremely powerful earthquakes were caused by this “underwater earthquake”.
A brief understanding of the differences between earthquakes at sea and earthquakes on land. By comparing the two photos above, you will know that earthquakes at sea not only have a huge impact on marine life, but also endanger humans, so don't underestimate earthquakes at sea. We need to pay attention to this!
It causes severe damage to shallow water biota, as tsunamis only affect the sea surface and about 10 meters below the sea surface, but creatures in deep seas are sometimes brought to shallow waters. maritime areas and die. , a large number of fish and shrimp in shallow marine areas died on land. However, the areas near the spring were good.
