There is always some convection current moving somewhere, and all earthquakes (except man-made induced ones) in general can be attributed to the convection movements of the lower and upper mantle. However, the 1976 Tangshan earthquake is believed to be a result of the Amur Plate/Subplate rotating and grinding against the Eurasian Plate.

Where was the worlds worst earth quake?
The Number 1 Deadliest Earthquake in World History.) The Shaanxi Earthquake.You've gotten through all the boring stuff. Now comes the big one. This earthquake started in Shaanxi, China, and devestated an area over 520 miles! More than 20 meter deep crevices were made during this earthquake.More than 97 countries were shaken by this enourmous earthquake. A staggering 830,000 people died during this massive tremor. Over 60% of some country's population were killed. The cost of this earthquake cannot be written in todays terms, because it is so large. This earthquake was only an 8 on the Richter Scale, only 1 Gigaton.Number 2.) The Tangshan Earthquake.On July 28, 1976, the "Great" Tangshan Earthquake struck Tangshan, Hebei. This shock was believed to be the largest earthquake of the 20th century. The Chinese Government said that 655,000 people were killed, but latest research has believed that the toll was not as much, only 255,000, compared to the 655,000. The earthquake only lasted 10 seconds, but the magnetude made up for the short time. Seismographs recorded this earthquake as a 8.2 in some areas, a 2.2 Gigaton earthquake. The earthquake struck very early in the morning, when people were asleep. This left very little time to react to this earthquake. Tangshan was believed to be a region with very low risk of earthquakes, so the buildings were not to be made earthquake-proof. The earthquake was 4 miles long by 5 miles wide, leaving a massive area crumbled. The total damage was nearly 10 billion yuan, or $1.3 billion.Number 3.) the Haiyuan Earthquake.240,000 people were killed on the December 16, 1920 earthquake that hit Haiyuan County, Ningxia. The Richter Scale recorded this earthquake as a 7.8, 700 Megatons, but is still being discussed. Chinese Geologists believe that the earthquake could have been a 8.5, 5.6 Gigatons, instead of a 7.8. This earthquake was felt for over 125 miles and the aftershocks lasted over 3 years. It was also called the 1920 Gansu Earthquake because Ningxia was a part of Gansu when the earthquake occurred.
What are the four steps that lead to an earthquake?
The four steps leading to an earthquake include the movement of tectonic plates and pressure developing over a long period at its boundary. Then the convection heat builds at the asthenosphere, and there is a sudden release of accumulated pressure from tectonic boundaries.
A convection current created during the day?
During the day, the Sun heats the Earth's surface, causing the air above it to also become hot and rise. As the hot air rises, it creates a convection current where it cools and eventually sinks back down as cooler air, creating a continuous circulation of air. This process helps distribute heat around the Earth and is a key mechanism in shaping weather patterns.
Why should you not go in an elevator during an earthquake?
It's safer to avoid elevators during an earthquake because they may malfunction or get stuck, trapping you inside. Additionally, if the power goes out during the earthquake, you could be left stranded in the elevator shaft. It is better to take the stairs if it is safe to do so during an earthquake.
Can shaking during an earthquake cause significant damage to buildings and infrastructure?
Yes, shaking during an earthquake can cause significant damage to buildings and infrastructure.
How many people died in the earthquake?
On July 28, 1976, a magnitude 7.8 earthquake hit the sleeping city of Tangshan, in northeastern China. The very large earthquake, striking an area where it was totally unexpected, obliterated the city of Tangshan and killed over 250,000 people - making it the deadliest earthquake of the twentieth century.
During convection hot material then moves to the side and . This circular pattern is called a convection current?
During convection, hot material rises due to its lower density, creating a convection current. As the material moves to the side, it cools down, becomes denser, and eventually sinks, completing the circular pattern of convection. This process is driven by temperature differences within the fluid.
During convection hot material do what?
During convection, hot material rises due to its lower density, creating a current that transfers heat from the hot material to cooler material. This process then causes the cooler material to sink and cycle back towards the heat source, creating a continuous convection current.

How does heat transfer during convection?
Heat transfer during convection occurs through the movement of fluids (liquids or gases). As the fluid is heated, it becomes less dense and rises, carrying heat energy with it. This movement creates a convection current, transferring heat from the hotter regions to the cooler regions.
Ask us anythingWhich best describes how air moves during convection?
During convection, air moves due to temperature differences. Warmer air molecules expand and become less dense, causing them to rise. Cooler, denser air then moves in to replace the rising warm air, creating a convection current. This cycle of warm air rising and cool air sinking is how air moves during convection.
Why do the tectonic plates collide that causes an earthquake?
The tectonic plates are sitting on molten lava. Due to convection currents the plates are moved around and can crash into each other causing earthquakes. Convection currents occur because of the core. The core of the earth is really hot. Therefore, it heats the molten rock near it and this rises. As it gets to the top it cools down and therefore sinks. This creates a circular current.
What is the kind of earthquake released during an earthquake?
Earthquake waves are called seismic waves.
Where is a danger spot during an earthquake?
the danger spot during an earthquake is at the epicenter wich is the place right above were the earthquake was originaly started.
