Epicenter
To completely describe where an earthquake started, you would need the coordinates of the earthquake's epicenter, the depth at which it originated within the Earth, and the fault line or tectonic plate boundary where the earthquake occurred. This information helps to pinpoint the exact location and provide insight into the geological context of the earthquake's origin.
The focus of an earthquake, also known as the hypocenter, is the actual location within the Earth’s crust where the earthquake originates. The epicenter is the point on the Earth's surface directly above the focus. The relationship between the focus and the epicenter helps scientists determine the exact location of the earthquake's origin.
At least three seismograph stations are needed to triangulate the exact location of an earthquake's epicenter. By comparing the arrival times of the seismic waves at different stations, scientists can pinpoint the epicenter where these intersect. More stations can provide a more accurate and precise location.
Scientists use instruments called seismometers to detect and record seismic waves emitted by earthquakes. By analyzing the timing and intensity of these waves at different monitoring stations, scientists can triangulate the epicenter of the earthquake and determine its exact location.
This is known as the focus or hypocentre of an earthquake.
The "epicenter" is the point on the surface above the "hypocenter" or "focus" of the earthquake underground.

The location for the magnitude 9.0 earthquake in Japan on March 11, 2011 was 129 kilometers (80 miles) off the east coast of the Oshika Peninsula, Tōhoku, near Sendai at a depth of 32 kilometers (20 miles).

Floods, large or small, happen on a daily basis somewhere in the world. You need to specify a location for an exact date for that location.
The January 12 Haitian earthquake occurred at a longitude of 72 degrees West. According to the US Geological Survey the exact co-ordinates were 18.457°N, 72.533°W.

Japan probably has one or more earthquakes every day. The most significant earthquake in Japan was the magnitude 9.0 Tōhoku earthquake on March 11, 2011 that occurred in the depths of the Pacific Ocean near the northeast coast of Honshu, Japan, about 130 kilometers (80 miles) east of the city of Sendai. Exact location: 38.297°N, 142.372°E
