Is the present day Sri Lanka the Ravana's Lanka?

Many scholars and learned people thought and propagated the idea that present day Sri Lanka (island country), very close to India, was the Lanka, described in Srimad Ramayana, and ruled by Ravana.  Is it a correct hypothesis? 

According to Srimad Ramayana, in order to search for Seeta at Lanka in Southern direction, Sri Hanuma flew 100 Yojanas over the ocean.

अञ्जलिं प्राङ्मुखः कृत्वा पवनायात्मयोओनयो |
ततो हि ववृधे गन्तुं दक्षिणो दक्षिणां दिश्म् ||      (Sundara Kanda 1 Sarga  9 sloka)

Hanuma turned towards east, saluted his father, the Lord of Wind and increased his body to go towards southern direction.



योजनानां शतं श्रीमांस्तीर्त्वाप्युत्तमविक्रमः |
अनिःस्वसन् कपिस्तत्र न ग्लानिमधिगच्छति ||     (Sundara Kanda 2 Sarga  3 sloka)



The glorious Hanuma with the best courage, even though crossing a hundred yojanas, was without a sigh and did not obtain any tiredness.



-----------------
A Yojana (Sanskrit : योजन ) is a Vedic measure of distance that was used in ancient India. It is equivalent to about 13 km (8 mi) for terrestrial use and 6400 km for cosmological distances as per modern measures of distance, although the exact value is disputed among scholars (between 8 and 13 km (5 and 8 mi)).  Some even put it as 26 Kms, depending on various calculations.  We can adopt 13 Kms to be on safe side.

------------------

Sri Lanka is at a distance of 24 kilometers (approx.) from Rameshwaram.  And, it is in the South-East direction from India but not in the Southern Direction.

Now, let us carefully study which words exactly  the Sage Valmiki used in describing Sri Hanuma's journey over the ocean. 


The Sage Valmiki used the words दक्षिणां दिश्म् (Southern direction) and योजनानां शतं( a Hundred yojanas).  If we calculate the the distance Sri Hanuma covered in terms of Kilometres, it will work out to 1,300 Kms (13 Kms x 100 Yojanas).  And, Sri Hunuma travelled 1,300 Kms in the Southern direction but not in the South-East direction.



Hence, in my opinion, Sri Hanuma travelled to and searched in a different Lanka, but not in the present day Sri Lanka.  Either original Lanka might have been got drowned in the sea or it might have got drifted to some other place, as there is no other Island at that distance.

Perhaps, the present day Madagascar, which is very close to present day African Continent, might be the Ravana's Lanka.
