672 GEOLOGY OF SAMOA AND THE ERUPTIONS IN SAVAII. 



every house is gone. It is dead again inland, but is running into 

 the sea. The volcano itself is as strong as ever. Last Thursday 

 week (September 13th) Dr. Linke registered an earthquake of 

 tremendous force some 3000 miles from here. 



Dr. Linke, meteorologist and seismologist at the Apia Observa- 

 tory, writes to me from Apia (Sept. 3rd, 1906), that the Val- 

 paraiso earthquake was registered by his seismograph, but the 

 volcano on Savaii was not influenced by the Chilian disturbance. 



In a letter in the " Samoanische Zeitung " for August 18th, 

 1906, Dr. Linke states as follows : — " It appears as if, since the 

 beginning of July- when magnetic disturbances commenced — 

 there is again increased activity." 



Second Postscript (added 23rd January, 1907). — News from 

 Tonga last month (Dec, 1906) state that the volcano of Tofua is 

 again active. A new crater has formed and there are, in all, 

 three active craters. The eruption is of a very explosive character. 

 Before 1906 Tofua had been quiescent about 40 years. The 

 volcano of Mauna Loa in Hawaii, on the same line, has also 

 become active.
