Berita koran Jawa Pos pagi ini, bhw suara gemuruh juga terdengar di daerah Kare 
- Madiun (lereng barat G. Wilis). Suara terdengar lbh jelas pada malam hari. 
Konon suara itu terdengar juga di Sedudo - Nganjuk (lereng timur G. Wilis). 
Selain itu, baru saja sy ditelepon seorang pejebat Pemkab Tulungagung yg 
kebetulan orang geologi, bhw di Tulungagung juga mulai terdengar suara gemuruh 
yaitu di daerah Besuki - Watulimo, terdengar paling nyaring di daerah Sedayu 
Gunung. Melihat perkembangan terakhir, setelah Ponorogo dan Trenggalek, kami di 
Pemprov Jatim akan kembali berkoordinasi dg Stasiun Geofisika Tretes utk dapat 
melakukan pemantauan lapangan di Tulungagung dan kemungkinan Madiun/ Nganjuk. 
Setelah baca tulisan mas Rovicky dan tanggapan pak Danny Hilman, sy berharap 
sumbang pemikiran tentang kasus ini dari para pakar di milis iagi-net ini. 
Matur nuwun.

Pardan - Surabaya.

Wah, gunung wilis ?
Saya hanya punya pengamatan 3 hari. Mungkin perlu pengamatan yg lebih
lama. Data yg saya peroleh dari BMKG tretes hanya beberapa hari saja.
Padahal kalau baca2 di USGS swarm itu bisa dua minggu bahkan dua
bulan.
Coba nanti cari data pengamatan yg lebih lama supaya penyebarannya lebih jelas.

Thanks
