Answer:

510

Explanation:

Recurrence interval involves the average estimated time or average spacing between events. It helps to estimate the time probability of an event taking place.

Calculating the recurrence interval we have:

[(820 - 260) + (1200 - 820) + (2100 - 1200) + (2300 - 2100)] / 4

= (560 + 380 + 900 + 200) / 4

= 2040/4 = 510

After the calculations, the recurrence interval of the earthquake that caused the disruption is 510 years.

How was the path of Hurricane Ike different than the storm of Galveston 1900
olga_2 [115]

Answer: After the hurricane, Galveston raised the elevation of many new buildings by more than 10 feet (3 meters). The city also built an extensive seawall to act as a buffer against future storms. Despite the reconstruction, the city's status as the premier shipping port was lost to Houston a few years after the disaster. Ike, however, is projected to head west on a path that will take it close to Hispaniola, Cuba, and the Florida Straits.”

nata0808 [166]

Answer:

Normal fault

Explanation:

Tensional stress occurs as a result of forces which could be wind, water etc pulling the rocks apart and forming faults. Faults are also known as a type of fracture which occurs between rocks.

Tensional stress along a fault can result in a dropped hanging-wall block relative to the footwall side(in a perpendicular position) thereby producing a normal fault.
