Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE affected_region ( region_id number, storm_id number, number_city_affected number )
TABLE: CREATE TABLE region ( region_id number, region_code text, region_name text )
TABLE: CREATE TABLE storm ( storm_id number, name text, dates_active text, max_speed number, damage_millions_usd number, number_deaths number )

### Question ###
What are the region names affected by the storm with a number of deaths of least 10?

### Accurate SQL ###

SELECT T2.region_name FROM affected_region AS T1 JOIN region AS T2 ON T1.region_id = T2.region_id JOIN storm AS T3 ON T1.storm_id = T3.storm_id WHERE T3.number_deaths >= 10
