Dari hasil data seismograf tercatat gelombang LONGITUDINAL 7. 30' 30'', sedangjab gelombang Transversal 7 33'50''. Hitunglah jarak episentralnya

kelas : 10
mapel : geografi
materi : seisme
kata kunci : jarak episentral

jawaban :

laska = {(s-p) - 1' } x 1000 km

= {( 7.33'50" - 7.30'30")} - 1' x 1000 km

= {(3'20")} - 1' x 1000 km
= (2'20") x 1000 km
= 2' x 1000 = 2000
= 20"/60'x 1000 = 333
= 2000 + 333
= 2.333 km

jadi jarak episentrumnya yaitu 2.333 km

semoga manfaat

Jawab :

Laska = [(s-p) - 1' ] × 1000 km
.
.
.
=[(7.33'50"-7.30'30")]- 1' × 1000 km
.
=[(3'20")] - 1' × 1000 km
.
=(2'20") × 1000 km
.
=2' × 1000 = 2000
.
=20"/60' × 1000 = 333
.
=2000 + 333
.
=2333
