Earthquakes occur every day in the world and are extremely dangerous. An earthquake is caused by a plate movement called a fault. The plate is part of the earth's outermost hard shell, consisting of the Earth's crust and the attached upper mantle, floating on the plastic like a gob. Faults are deep underground, they always move slowly, and we do not even feel it. Seismologists are studying ways to predict earthquakes in order to be safer in the earthquake by researching and studying seismic waves.
Earthquake standard reports include magnitude, date and time of occurrence, geographical coordinates of the epicenter, depth of the epicenter, geographic area, distance to the population center, location uncertainty, and several parameters included in the USGS Earthquake Report Quantity etc) and unique event ID. In spite of the traditional use of relatively slow seismic waves to detect earthquakes, scientists will gravitate in 2016 to provide an instantaneous detection of the earthquake, and the 2011 Northeast ("Fukushima") earthquake We can analyze the gravity record related to the.

On November 18, an earthquake of magnitude 7.5 occurred on the Richter scale. The epicenter was in the Senegal Channel between the Virgin Islands Puerto Rico and St. Croix. The tsunami caused by the earthquake occurred in the inland of near 150 meters (490 feet) at the bottom of the coast of Yabucoa. Hundreds of women and men rebelled against Spain on 23rd September because Puerto Rico became independent. Uprising, Lares cried, or Lares' rebellion). The rebellion was composed of a group of people led by Dr. Ramón Emerio Betans (which is not allowed to enter the island) and Segundo Luis · Belvis. The most important people in the uprising were Manuel Lohas, Matthias Brookman, Joaquin Parilla, Francisco Ramirez.
