Historians believe that Chinese philosopher Chang Heng invented the first device to measure earthquakes in AD 132. It is described as a large urn with eight dragon heads popping out of it. Each head faced one of the eight principal directions of the compass- North,South,East,West,Northeast,Southeast,Northwest and Southwest. And a toadwith its mouth open squatted below each dragon head. When an earthquake hit, a ball would release from one or more of the eight dragons and fall into the toads mouth. By this, the direction of the approaching earthquqke could be determined. Reports indicate that Heng's device detected an earthquake 400 miles/ 644 km away. There were other devices like these to detect earthquakes but this was the best one. Devices to "measure" earthquakes were not very accurate in ancient times, in fact, there were hardly any such devices.
Currently, no successful predictions of earthquakes have been made. Earthquakes are highly unpredictable and complex phenomena, making it challenging to accurately forecast when and where they will occur. Most efforts focus on early warning systems rather than precise prediction.
Yes. Earthquakes of SOME intensity happen SOMEWHERE every day. There were 2 strong earthquakes today, one in Italy, one in Tonga. The running tally for 26 October 2016 from earthquaketrack.com:99 earthquakes today681 earthquakes in the past 7 days3,156 earthquakes in the past month41,088 earthquakes in the past year
Yes, Vietnam is located in a seismically active zone and has experienced earthquakes in the past. The country lies on the boundaries of several tectonic plates, making it prone to seismic activity. While most earthquakes in Vietnam are relatively small and not widely felt, there have been larger earthquakes in the past, particularly in the northern and central regions of the country.
Correct, earthquakes cannot be reliably predicted in terms of when they will occur, where they will happen, and how large they will be. Scientists can forecast the likelihood of earthquakes in certain areas based on historical data and ongoing monitoring, but predicting specific times and locations remains a significant challenge.
Earthquakes cannot be accurately predicted. However, scientists use techniques like monitoring fault lines, ground deformation, and historical earthquake data to assess the probability of an earthquake occurring in California. Early warning systems like ShakeAlert can provide seconds to minutes of advance notice before strong shaking from an earthquake reaches a location.
Probably the biggest problem with earthquakes is that they can't be predicted.
there are millions of earthqukes that have past
No. There is no way of predicting earthquakes and it is unlikely that a method to do so will be developed in the near future.
They can't be predicted and that is the problem. Geologists monitor active faults for signs of movement.
Yes. Earthquakes are a common occurrence in California, and some of the faults have been known to produce major earthquakes. It is inevitable that more major earthquakes will strike California in the future, but there is no way of knowing when or where they will be centered.
You can't predict earthquakes
Predicted is the past participle of predict. Predicting is the present participle.
Seismologists not meteorologists study earthquakes. Generally earthquakes can be predicted by measuring fore-quakes which often precede larger earthquakes.
Short term predictions of earthquake behaviour or even earthquake predictions in general have not occured yet. Many even question if earthquakes will ever be able to be predicted. Even the earthquakes that have supposedly been predicted correctly have controversy behind the method
Nobody knows. Several times in the past it has been predicted, but it hasn't happened yet.
Predicting earthquakes in the East is like predicting snow in the North.
Earthquakes can never be predicted because Mother Nature is a surprise to us all
