the epicentre is just above the focus of an eq
The focus is where the greatest destruction occurs due to the shockwaves being most powerful here.
Therefore when you know where the focus is, above it (i.e. the ground) is the epicentre

Seismologists use two main devices to measure an earthquake: a seismograph and a seismoscope. The seismograph is an instrument that measures seismic waves caused by an earthquake. The seismograph has three main devices, the Richter Magnitude Scale, the Modified Mercalli Intensity Scale, and the Moment-Magnitude Scale. The seismoscope is an instrument that measures the occurrence or the time of an occurrence of an earthquake ("Inventors"). Unlike other measuring devices, the seismoscope is a simple device without any technological background. The seismoscope is the oldest and most accurate instrument for measuring direction.
I have this question on a science lab now. Indonesia was located closest to the original earthquake's epicenter and without a warning system in place, the population of citizens and tourists did not have time to reach safety.
To determine the epicenter of a hypothetical earthquake, you need specific information about the earthquake, such as the locations of seismic stations that detected the tremors and the time it took for the seismic waves to reach those stations. By analyzing the data from at least three different seismic stations, geologists can triangulate the epicenter's location. Without specific details or coordinates, it's not possible to identify the epicenter accurately.
The seismograph for a larger earthquake would show stronger and more prolonged seismic waves compared to a smaller earthquake. The amplitude and duration of the seismic waves recorded by the seismograph would be greater for the larger earthquake.
No. Without a 3rd peice of data from another station, there will always be 2 different possible locations of the epicenter. You must have 3 seismographs to collect the data.
To locate the epicenter you use the speed of waves that travel from the epicenter to the seismic sensor locations. With two sensors you are able to narrow the location to two places (when on a surface using intersecting hyperbolas). With a third sensor you have the location on a surface and below ground. This third sensor is why they call it tri - angulation but the angles are hard to find without HS trigonometry and other mathematics.
Without earthquakes, there would be a greater population and less damage. Also, earthquakes kill so many people.

To determine the epicenter of an earthquake among the locations you provided, one would need specific seismic data indicating the origin of the quake. The epicenter is defined as the point on the Earth's surface directly above where the earthquake originates, which can vary greatly depending on the geological conditions and tectonic activity of the region. Without additional context or seismic information, it's impossible to identify the epicenter among the listed cities.
That is impossible to tell. Smaller earthquakes occur more frequently, to the extent that the majority of earthquakes are too small to event be felt. Without a sophisticated seismic network, many earthquakes will not even be detected.
No. Like all earthquakes, it struck without warning.
No, earthquakes can occur at any time of the year without following a specific seasonal pattern. Earthquakes are caused by the movement of tectonic plates beneath the Earth's surface, which can happen at any time.
