Received a delayed radiogram and responded while about fifteen miles south of Sannak Island, Alaska:

To Govt. R. C. Manning
Reported eruption probably off Pavlof see if people at Pavlof Bay and vicinity need assistance acknowledge.

To Capt. Reynolds, Unalaska.
Manning fifteen miles south of Sannak Island, your radiograms of the fifth, sixth and tenth just received ten thirty p.m. will investigate conditions at Pavlof Bay and vicinity at once, arrive there about two p.m. tomorrow.

Likely more to come...

Manning, July 11, 1914. Continuation of entries concerning the Pavlof Volcano:

12:30 Commanding officer landed at Belkofsky Village to investigate report that Pavlof Volcano had been in eruption; found that it had been active for about half a day on July 5; no damage was done at Belkofsky, and the people there had no knowledge of harm done elsewhere.
3:15 received the following radiogram from the U.S. Coast Survey vessel "Patterson", at Karpa Island; "About a ton of ashes fell on the ship and it was as dark as night. We did not investigate the damage on mainland."
6:30 off position indicated for Pavlof village water shoaling rapidly to 6 fathoms, backed out, turned and stood out of bay there being no evidence of any
volcanic disturbance and no signs of a village.

Manning, July 12, 1914. Final log entries for the Pavlof Volcano, Alaska:

Sailing up Unga Strait:

6:30 Noticed fresh volcanic ash on the east slope of Pavlof volcano but no ash on any of the surrounding country nor in the water.

Passing Cape Swedania:

10:40 No volcanic ash or other evidence of a recent volcanic disturbance was to be seen on the peninsula or any of the islands passed.

The next few hours navigated around Karpa, through Gorman and Korovin Straits and High Island.
Meridian to 4PM:

Examined the islands for traces of volcanic ash, but saw no traces.

Anchored off Sand Point:

5:10 Commanding Officer conferred with settlers and learned that a light fall of black volcanic ~~~~~ had taken place on the 5th instant for a period of one hour,
the fall occurring at Sand Point at 3:00 p.m. and at Simeonof Island at 7:00 p.m. The fall did no damage and all traces were nearly obliterated by rain fall.

According to this site, under the Eruptive History tab, the Pavlof eruption occurred on July 6, 1914, but the crew of the Manning were informed by a couple of sources that it occurred on July 5. It was in the afternoon. So even if they are going by GMT it would still be July 5, although it would have been July 6 on the other side of the International Date Line.

Haida, June 21st 1928:

Earthquake reported within radius of 100 miles at 06:30 AM. No disturbance noticed in position 58 20 N 149 40 W. HMS Durban felt disturbance badly in position 60 11 N 147 3 W.

This is the same HMS Durban we did back in Phase 1+2, but we only did 1921 to 1923 according to NavalHistory.

8AM to Noon:

Passed through water in which pieces of pumice stone, 6 to 8 inches in length, were floating. Air was filled with fine volcanic dust from recent eruption.

Noon to 4 PM:

Thick smoke latter part [of watch], with fall of volcanic dust, air heavy with sulphur fumes, and rise of 5° in temperature in wake of Katmai volcano, which is evidently still in eruption.

14:30 smoke being too thick to see further than 4 ship lengths

EDIT: Also June 27:

Kearsarge 13th Aug 1868, Caldera, Chili

2000 Indications of an Earthquake experienced during the watch. Tremulous motion to ship and agitation in the water.
Called "All hands" at 10 secured boats battery as for sea. Started fires at 10:40. Piped down at 11:20.
fan forced ?? came in at an interval of half an hour, occasioning a rise of about 20ft in the water which flooded the mole?? causing considerable damage to the shipping.

(A little more follows on the next page)

The first word is hard to make out, but is it Ten (or Two) bores?

And, it is a mole:

Definition of mole (Entry 4 of 6)
1 : a massive work formed of masonry and large stones or earth laid in the sea as a pier or breakwater
2 : the harbor formed by a mole

[Randi]

fan forced ??
Maybe Two bores, as in tidal bores?

mole ??
Probably refers to https://en.wikipedia.org/wiki/Mole_(architecture)

[Randi]

Looks like we were working on it at the same time and came to the same conclusions

0400 Several earthquake shocks were experienced during the watch.

Here's a very interesting link about the earthquake off Arica, Peru on 13 August, 1868. The U.S. Navy had two ships at Arica at the time. One was lost with all but three hands. The other was driven 500 yards above the high water mark, but lost only one person. There are so interesting photos included in the article. No mention of the Kearsarge, though.
