Earthquakes have become the fascination of many people today, mostly because of all the doomsday theories that have been popping lately. In a nutshell the movements of the earth’s crust cause earthquakes, although what some people aren’t aware of is that even a minor movement is enough to cause powerful earthquakes of large magnitudes. Many scientists believe that the series of earthquakes that happened in New Madrid during 1811-1812 was caused by the impact of a large meteorite to the surface of the earth. That would be like experiencing at least 8,000 quakes every day and one earthquake for every 11 seconds. Fact #4The strongest earthquake that was ever recorded so far was the 1960 earthquake in Chile. Although the exact death toll for the Valdivia earthquake has never been given a certain number, an estimated 5,700 people were killed. Today most casualties that rooted from earthquakes are caused by the destruction of man-made structures.
Fact #6A lot of people have the false belief that California is the state that is most prone to earthquakes.
Those who are living in Alaska are probably used to heavy earthquakes considering that they experience 7.0 magnitude earthquakes every year or so. Fact #7In the United States, the largest earthquake ever recorded wasn’t in California as well. Fact #10The most recent earthquake that claimed hundreds of thousands of lives was the Indian Ocean undersea earthquake of 2004.
Fact #12There are actually certain areas on Earth that don’t experience earthquakes for long periods of time. Fact #13Replica of a 1st century Chinese seismometer (Photo credit: Wikipedia)Before scientists used electronic gadgets to measure the power of an earthquake, seismologists used spring-pendulum seismometers. The Japan Meteorological Agency on Tuesday said that a minor volcanic eruption occurred at Mount Asama in central Japan, which is located approximately 100 miles northwest of Tokyo. 1. There are approximately 1,500 active volcanoes in the world, of which 110 are located in Japan. Locals at Oshima Island some 70 miles south of Japan prepare to evacuate with Mount Mihara erupting in the background in November 1986.

4. The most recent volcanic eruption which caused human casualties occurred in September at Mount Ontake in central Japan, which killed 56 people. The government estimated in 2004 that an eruption at Mount Fuji would affect over 400,000 people including those in Tokyo and cause a damage of as much as ?2.5 trillion (about $20 billion).
Japan Real Time is a newsy, concise guide to what works, what doesn’t and why in the one-time poster child for Asian development, as it struggles to keep pace with faster-growing neighbors while competing with Europe for Michelin-rated restaurants. One of the most significant features of Japanese geography is the large number of volcanoes. This is an area of high seismic and volcanic activity from New Zealand, up through Japan, across to Alaska, and down the west coasts of North and South America. With a whopping 9.5 magnitude on the MMS, the Valdivia earthquake tops the list for strongest earthquakes. The earthquake also caused a large tsunami that damaged the shores of Hawaii, Japan, Australia and New Zealand. Most deaths are caused by other natural events that were triggered by the earthquake like landslides, tsunamis or even avalanches. Contrary to popular belief, it is actually the state of Alaska that is highly vulnerable to earthquakes and it is even one of the most active areas in the world in terms of seismologic activity. In 1964, a 9.2 magnitude earthquake violently shook the grounds of Prince William Sound, Alaska. Although the earthquake was only an 8.0 magnitude on the MMS scale, it still took the lives of about 830,000 people.
In 1975-1995, there were no earthquakes recorded in Florida, North Dakota, Iowa and Wisconsin.
These spring-pendulum seismometers were huge devices used to record the motion produced by earthquakes. Just one large earthquake in a densely populated area in the United States can cause enough damage that will lead to a loss of about $200 billion.
They are scattered all over the country from Hokkaido in the north to Okinawa in the south, and some are underwater. An eruption in August 1783 killed 1,151 from mud and pyroclastic flow and flooding of a nearby river, according to the meteorological agency.

A panel of experts working under the meteorological agency on Monday said that there were volcanic eruptions in five locations in Japan just between Feb. The most lethal volcano disaster in Japan since the 18th century occurred in May 1792, when Mount Unzen in Nagasaki triggered an avalanche of debris that sent a 23-meter tsunami to the opposite shore of Ariake Sea. While it hasn’t erupted since 1707, the meteorological agency’s panel said in its report Monday that following a magnitude 6.4 earthquake on March 15, 2011, in a nearby area, the mountain has continued to show seismic activity.

You might have a different reason in mind, but whatever that is, we’re sure that the 15 facts about earthquakes that we have in store can definitely spark your interest and even perhaps change your perception about earthquakes. The United States Geographical Survey has revealed that there are about 3 million earthquakes every year. In fact, North Dakota and Florida have the least occurrences of earthquakes in the United States. In fact, an underwater volcano has been erupting in the Ogasawara island chain, located approximately 1,000 kilometers south of Tokyo. These volcanoes are a force of destruction, not only on land – the 1923 earthquake centered around Tokyo killed more than 140,000 people – but they also generate Tsunamis, such as the devastating one that hit north Japan on March 11, 2011. Strong earthquakes are usually followed by a series of aftershocks that can last for several months.
Since it begun erupting in 2013, the lava has fused with Nishinoshima island and the area of the combined island continues to grow. This massive tidal wave was caused by the strongest earthquake recorded in Japan’s history.
