Oh, and there was a minor earthquake in Latur as well. Slight tremors were felt around 4.30 in the evening.
Earthquakes are absolutely fascinating. And they aren't all that rare. It is estimated that there are 500,000 detectable earthquakes in the world each year. 100,000 of those can be felt, and 100 of them cause damage. So there are around 150 earthquakes with a magnitude greater than 2.5 every week. Which works out to around a little over 20 everyday. That's almost one every hour.
And while we are talking about cool earthquake facts. Here are some more:
Before electronics allowed recordings of large earthquakes, scientists built large spring-pendulum seismometers in an attempt to record the long-period motion produced by such quakes. The largest one weighed about 15 tons. There is a medium-sized one three stories high in Mexico City that is still in operation.
The first "pendulum seismoscope" to measure the shaking of the ground during an earthquake was developed in 1751, and it wasn't until 1855 that faults were recognized as the source of earthquakes.
Moonquakes ("earthquakes" on the moon) do occur, but they happen less frequently and have smaller magnitudes than earthquakes on the Earth. It appears they are related to the tidal stresses associated with the varying distance between the Earth and Moon. They also occur at great depth, about halfway between the surface and the center of the moon.
Although both are sea waves, a tsunami and a tidal wave are two different unrelated phenomenona. A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth. A tsunami is a sea wave caused by an underwater earthquake or landslide (usually triggered by an earthquake) displacing the ocean water.
If you've got this far, maybe you like to track earthquakes like I do. And so you might like to check this out.first published:January 04, 2006, 18:00 ISTlast updated:January 04, 2006, 18:00 IST

There have been five earthquakes off the US coast in the Gulf of California today. The weakest was 4.4 on the Richter scale. And the strongest was 6.7 on the Richter scale.
