It's just a map error. They happen all the time - once they had a super thin park that ran from Pittsburgh to Texas - it was sort of fun to try to trace it all the way (I gave up, but someone persevered all the way to the end of it).<p>You can report it to google - there's a report link on the page.
That looks like somebody messed up while converting image data to vector data in their GIS.<p>Sometimes you see stuff similar to this when you have a bunch of coordinates and a few of them are corrupted - then the lines would shoot off somewhere, and sometimes you might not even notice it. BUT this doesn't look like that - hell it could be pastefuck.
Probably a bug; at least Nokia Maps has no such thing: <a href="https://www.here.com/discover?map=14.1088,120.63979,8,normal" rel="nofollow">https://www.here.com/discover?map=14.1088,120.63979,8,normal</a>
Similarly, it's always fun to find out what has appeared at Null Island recently: <a href="http://tools.wmflabs.org/geohack/geohack.php?pagename=Null_Island&params=0_N_0_E_type:isle" rel="nofollow">http://tools.wmflabs.org/geohack/geohack.php?pagename=Null_I...</a>
Mapmakers (and dictionary makers alike) often introduce small, purposeful errors so that they can track who steals their data. This could be Google's (not very subtle) attempt.
Similar situation here; this "peninsula" doesn't really exist:<p><a href="https://www.google.com.ph/maps/place/23%C2%B047'02.5%22S+35%C2%B024'23.1%22E/@-23.784016,35.40641,17z/data=!3m1!4b1!4m2!3m1!1s0x0:0x0" rel="nofollow">https://www.google.com.ph/maps/place/23%C2%B047'02.5%22S+35%...</a><p>I always assumed that google uses some kind of algorithm to detect land/sea borders, and it messed up.
It'll be a map error; last year they removed one of the Scottish islands by mistake - <a href="http://www.bbc.co.uk/news/uk-scotland-glasgow-west-23331456" rel="nofollow">http://www.bbc.co.uk/news/uk-scotland-glasgow-west-23331456</a>
Remember kids, you shouldn't use OpenStreetMap because that's crowd-sourced, and doesn't have the same rigorous attention to detail and quality standards are a Real Professional Map like Google Maps.
