Hi all, I'm trying to extract earthquake tweets from Twitter with specific long/lat coordinates thand en store into csv file.. 
However, the result returns tweets NOT specific to locaiton parameters, does anyone know why? Here is my code:

csvFile = open('seattle.csv', 'a')
csvWriter = csv.writer(csvFile)

for tweet in tweepy.Cursor(api.search,q="#earthquake",count=100,
                           location= "47.6126,-122.6222, 50mi",
                           lang="en",
                           since="2017-04-03").items():
     if tweet.geo != None:
##            tweetlist.append(tweet.geo)
            print (tweet.created_at, tweet.text)
            tweettime = str(tweet.created_at)
            text = str(tweet.text.encode('utf-8'))
            x = str(tweet.geo['coordinates'][1])
            y = str(tweet.geo['coordinates'][0])

            print text

            imgurl = ""

            if "http" in text:
                splitlist = text.split("http")
                if len(splitlist) == 2:
                    if "http" in text:
                        urlhashtagsplit = splitlist[1].split(" ")

                        imgurl = "http" + urlhashtagsplit[0]
                    else:
                        imgurl = "http" + splitlist[1]
                        
                csvWriter.writerow([x,y,imgurl,text,tweettime])
