Day_111 : Earthquake Information (1)

Introduce you two earthquake information websites. 1) The Earthquake Track 2) J-RISQ

1) The Earthquake Track

The Earthquake Track is useful to overview the earthquake occurrence situation in the world (Figure 1). As you can see in the below figure, every day’s earthquake occurrence situation such as how many times the earthquake occurred, what is the biggest earthquake of the day, and the earthquake locations on the map can be seen. Also, we can access to the detailed information of the quakes.

Figure 2 shows J-RISQ provided by the National Research Institute for Earth Science and Disaster Prevention (NIED).

Figure 2  J-RISQ website

As you can see the Figure 2, this site does not only provide earthquake (hazard) information but also affected population estimation (exposure). In addition, the site gives us historical information of the affected area. You can also refer prediction data on the map such as earthquake distribution of 2% probability of exceedance in 50 years and distribution of return period of 50,000-year.
