About
This dataset provides a collection of records for 782 earthquakes that occurred globally between 1st January 2001 and 1st January 2023. It serves as a valuable resource for seismic research, enabling in-depth analysis of earthquake phenomena, their characteristics, and impacts. The dataset includes crucial details such as magnitude, date and time, location, and various seismic measurement parameters, offering insights into significant events and their geophysical context.
Columns
- title: The name or title assigned to the earthquake event. There are 984 unique titles out of 1000 valid entries.
- magnitude: The measured magnitude of the earthquake. Values range from 6.5 to 9.1, with a mean of 6.94 and a standard deviation of 0.44.
- date_time: The precise date and time when the earthquake occurred. There are 990 unique date and time entries out of 1000 valid entries.
- cdi: The maximum reported intensity for the event range, ranging from 0 to 9. The mean CDI is 3.6 with a standard deviation of 3.33.
- mmi: The maximum estimated instrumental intensity for the event, with values from 1 to 10. The mean MMI is 6.03 and the standard deviation is 1.43.
- alert: Indicates the alert level associated with the event, which can be "green", "yellow", "orange", or "red". 55% of entries are missing this value, while "green" is the most common alert level at 35%.
- tsunami: A binary indicator, with "1" denoting events in oceanic regions potentially causing a tsunami, and "0" for non-oceanic events. 32.5% of events are marked as potentially causing a tsunami.
- sig: A numerical value representing the significance of the event, with higher numbers indicating greater significance. This value is determined by factors like magnitude, maximum MMI, felt reports, and estimated impact. Values range from 650 to 2910, with a mean of 848.
- net: The ID of the data contributor network, identifying the preferred source of information for the event. "us" is the most common network, accounting for 96% of entries.
- nst: The total number of seismic stations utilised to determine the earthquake's location. Values range from 0 to 934, with a mean of 194.
- dmin: The horizontal distance from the epicentre to the nearest seismic station. Values range from 0 to 17.7, with a mean of 1.13.
- gap: The largest azimuthal gap (in degrees) between azimuthally adjacent stations. A smaller gap generally indicates more reliable horizontal position calculation. Values range from 0 to 239, with a mean of 20.9. Gaps exceeding 180 degrees often suggest large location and depth uncertainties.
- magType: The method or algorithm used to calculate the event's preferred magnitude. "mww" is the most common type at 50%.
- depth: The depth (in kilometres) where the earthquake rupture begins. Values range from 2.7 to 671, with a mean of 74.6.
- latitude: The geographical latitude coordinate for the earthquake's location, ranging from -61.8 to 71.6.
- longitude: The geographical longitude coordinate for the earthquake's location, ranging from -180 to 180.
- location: A textual description of the specific location within the country. "Kokopo, Papua New Guinea" is the most common location, making up 3% of entries. 1% of entries are missing this information.
- continent: The continent of the country affected by the earthquake. This column has 72% missing values, with "Asia" being the most common valid entry at 14%.
- country: The affected country. This column has 35% missing values, with "Indonesia" being the most common valid entry at 14%.
