11014 20 Apr 2019 @ 1333 --- Janet Jones Thumps started - larger bubbles rising than prior to the Sept 2018 energy surge. Thumps lasted a full 10 minutes with the strongest at the start. During the start of the thumps, the bubbles were strong enough to emit a sizzling sound, but I wouldn’t classify them as a “bubble shower” — not concentrated enough.

10084 07 Sep 2018 @ 1328 07 Sep 2018 @ 1341 Janet Jones Arrived to a full pool with bubbles and no thumps. Noticed much heavier overflow as I walked up. The full pool and bubbles continued. At 1330 bubbles increased. 1332 thumps began. 1338 - pause in thumps. 1339 - restart of thumps. 1341 - thumps quit suddenly and pool dropped.
