cleanES_1: Example 1. Cleaned dataset

In Juanin2691/toolsEarthquakes: Tools for cleaning and ploting data from The Significant Earthquake Database

Description

Example dataset of eq_clean_data(data = Earthquakes)

Usage

cleanES_1

Format

A data frame with 5508 rows and 11 variables:

I_D

integer The unique numeric identifier of the record.

FLAG_TSUNAMI

character When a tsunami was generated by an earthquake, "Tsu" appears in the Assoc Tsu column. There should also be a "TSU" link in the Assoc column which is linked to the tsunami event database. The TSU link will display additional tsunami event information in a new browser window.

FOCAL_DEPTH

integer Valid values: 0 to 700 km The depth of the earthquake is given in kilometers.

EQ_PRIMARY

double Valid values: 0.0 to 9.9 The value in this column contains the primary earthquake magnitude. Magnitude measures the energy released at the source of the earthquake.

EQ_MAG_MW

double Valid values: 0.0 to 9.9 The Mw magnitude is based on the moment magnitude scale. Moment is a physical quantity proportional to the slip on the fault times the area of the fault surface that slips; it is related to the total energy released in the EQ.

EQ_MAG_MS

double Valid values: 0.0 to 9.9 The Ms magnitude is the surface-wave magnitude of the earthquake. The magnitude is a measure of seismic energy. The magnitude scale is logarithmic. An increase of one in magnitude represents a tenfold increase in the recorded wave amplitude.

EQ_MAG_MB

character Valid values: 0.0 to 9.9 The Mb magnitude is the compressional body wave (P-wave) magnitude. The magnitude is a measure of seismic energy. The magnitude scale is logarithmic. An increase of one in magnitude represents a tenfold increase in the recorded wave amplitude.

EQ_MAG_ML

double Valid values: 0.0 to 9.9 The ML magnitude was the original magnitude relationship defined by Richter and Gutenberg for local earthquakes in 1935.

EQ_MAG_MFA

character Valid values: 0.0 to 9.9 The Mfa magnitudes are computed from the felt area, for earthquakes that occurred before seismic instruments were in general use.

EQ_MAG_UNK

double Valid values: 0.0 to 9.9 The computational method for the earthquake magnitude was unknown and could not be determined from the published sources.

INTENSITY

integer Valid values: 1 to 12 The Modified Mercalli Intensity (Int) is given in Roman Numerals (converted to numbers in the digital database).

COUNTRY

character The Country where the Earthquake occurred

STATE

character The two-letter State or Province abbreviation where the Earthquake occurred.

LOCATION_NAME

character The Country, State, Province or City where the Earthquake occurred. This is only an approximate geographic location. Events prior to 1900 were not instrumentally located, therefore, the location given is based on the latitude and longitude of the city where the damage occurred.

LATITUDE

double Valid values: -90 to +90 Latitude: 0 to 90 (Northern Hemisphere) -90 to 0 (Southern Hemisphere)

LONGITUDE

double Valid values: -180 to +180 Longitude: 0 to 180 (Eastern Hemisphere) -180 to 0 (Western Hemisphere)
