Description

This function creates an interactive leaflet map with the earthquake locations.

Usage

eq_map(data, annot_col = "DATE")

Arguments

data	A data frame or tibble with spatial coordinates (LONGITUDE, LATITUDE) and the earthquake magnitude (EQ_PRIMARY).
annot_col	A column contained in data whose information will be displayed in the pop-up window.

Value

An interactive leaflet map with the earthquake locations. The marker size is proportional to the earthquake magnitude (EQ_PRIMARY). When clicking on a marker, a pop-up window will open.

Examples

# date pop-up as in figure 1 of module 3
file <- system.file("extdata", "earthquakes.tsv.gz", package = "NOAAeq")
library(magrittr)
readr::read_delim(file = file, delim = "\t") %>%
  eq_clean_data() %>%
  dplyr::filter(COUNTRY == "MEXICO" & lubridate::year(DATE) >= 2000) %>%
  eq_map(annot_col = "DATE")
