Here’s a map of earthquake location and magnitude (>=5.5) from 1965-2016. The data may be found on Kaggle.

WGS84_proj <- "+proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0"
NE_proj <- "+proj=natearth +lon_0=170"
quakes <- read_csv(here::here("data", "kaggle_earthquakes_database.csv"),
  skip = 3, col_types = cols(Date = col_date(format = "%d/%m/%Y")))
quakes_sf <- quakes |> 
  st_as_sf(coords = c("Longitude", "Latitude"),
    crs = WGS84_proj)
quakes_sf_trans <- st_transform(quakes_sf, NE_proj)
